Coronavirus relief negotiations hit another wall, talk of merging aid with government funding worries experts – ABC News

Coronavirus relief negotiations hit another wall, talk of merging aid with government funding worries experts – ABC News

August 14, 2020

Coronavirus relief talks hit a wall once again Wednesday, as negotiators appeared completely unable to find common ground and lawmakers poised to leave Washington for the month-long August recess.

After five days with no outreach, Treasury Secretary Steven Mnuchin called House Speaker Nancy Pelosi on Wednesday to discuss a way forward, but the speaker, in a joint statement with Senate Democratic Leader Chuck Schumer, made clear that the conversation failed to break the intractable logjam.

"Democrats have compromised. Repeatedly, we have made clear to the Administration that we are willing to come down $1 trillion if they will come up $1 trillion. However, it is clear that the Administration still does not grasp the magnitude of the problems that American families are facing," the two top Democratic negotiators said.

The statement came after Mnuchin appeared on Fox Business pushing Democrats to accept a $1 trillion piecemeal package, something Pelosi and Schumer have refused, saying the size and scale of the pandemic crisis calls for sweeping legislation.

"My view on a negotiation is you agree on the things that you can agree on, pass legislation that's good for the American public, and then come back always for another bill," said Mnuchin, who, along with White House Chief of Staff Mark Meadows, has been negotiating with Democratic lawmakers.

White House Chief of Staff Mark Meadows and Secretary of the Treasury Steven Mnuchin speak to members of the press after a meeting at the office of Speaker of the House Rep. Nancy Pelosi at the U.S. Capitol, Aug. 7, 2020 in Washington, DC.

Senate Majority Leader Mitch McConnell, who so far has not been present at the table with negotiators, continued to try to pin the blame for the impasse on Schumer and Pelosi.

"These two individuals are letting the wish lists of wealthy coastal elites stand between every working family in America and the additional help they deserve," McConnell, R-Ky. , said Wednesday.

Mnuchin and Democratic negotiators left the door open to future talks on Wednesday, but the two sides have hardly budged after weeks of negotiations. The broken state of the pivotal talks was shocking to even the most seasoned observers.

"It didn't enter my mind that they wouldn't get a deal," said longtime budget expert Maya MacGuineas, president of the nonpartisan Committee for a Responsible Federal Budget. "This really may be signs of complete dysfunction. It's truly scary that our lawmakers are not able to compromise in order to get something done for the American people. This situation is both more dire and the chance of them coming together is much less, and those two things combined make those observers like me worry about the ability of our lawmakers to find common ground."

With a compromise out of view and lawmakers poised to recess for the month, the path forward for any rescue bill became more fraught as any coronavirus relief aid could possibly be merged with a short-term government funding bill, called a continuing resolution or CR. And any intransigence then -- in a worst-case scenario -- might ultimately lead to a government shutdown.

"That's what it looks like," Senate Appropriations Committee Chairman Richard Shelby said last Thursday of merging coronavirus aid with a CR, adding that passing the 12 regular annual government spending bills by the end of the fiscal year, Sept. 30, was probably not likely. "I think that's the road we're headed down -- a CR. We've been on that track for about a month or so. Unless the Democrats agree, like we have the last two years to all vote together against extraneous things other than appropriations, we're not going to have a markup. We'd just waste everybody's time. So I think we're headed for a CR. I wouldn't say it's inevitable. It's getting close, though."

Former long-time Senate budget director and appropriations staffer William Hoagland told ABC News that he thinks McConnell has always wanted it this way.

"I truly believe, with some collaboration from some current Senate staff, that McConnell has always wanted to move the COVID package to one vote in September tied to a CR," Hoagland, now a Bipartisan Policy Center senior vice president, told ABC News. "Politically, he did not want to force a vote in the Senate and lose maybe half of his caucus. He also did not want to have vulnerable GOP senators this fall take some tough votes he might not be able to control. So, despite what I understand was some statements about getting back to negotiating, with (White House Chief of Staff) Meadows on vacation this week and as you said, Schumer leaving, along with conventions upcoming, no question we are off until after Labor Day on any action.

Asked for a reaction, an aide to McConnell pointed ABC News to the Republican leader's remarks on Wednesday calling on Democrats to set aside what he referred to a "liberal wish list" and get back to the negotiating table.

One senior Senate GOP aide told ABC News that there is a possibility of a CR that would fund the government until sometime into November or potentially through mid-December, but that any final decisions had not yet been made.

To MacGuineas and Hoagland, the choice of a continuing resolution is risky.

"A CR is already a symbol of failure," MacGuineas said. "To combine that with a second failure of not passing an emergency bill that is well thought out and incredibly transparent, to have two failures smooshed into one big bill is basically a massive sign of dysfunction in all of the areas where we should be governing."

Hoagland said, "Without a resolution to a fifth stimulus package, I see no way that many of the same issues in July and early August won't reemerge on a must-do CR bill."

With jobless Americans still numbering in the multi-millions, a moratorium on evictions and utilities' shutoffs having expired and the small business loan program closed -- all due to inaction in Congress -- it remains to be seen where the political blame might land ahead of crucial elections in the fall.

Kyle Kondik, managing editor of Larry Sabato's Crystal Ball who analyzes elections for the UVA Center for Politics, sounded the alarm for Republicans, warning that that the party in power is usually the one that gets the blame if people perceive the state of the country to be in disarray on Election Day.

"To me the stakes are politically higher for Republicans to intervene in the economy. If things get really bad in the fall, they are more likely to face consequences than Democrats are," Kondik told ABC News.

House Speaker Nancy Pelosi speaks, flanked by Senate Minority Leader Chuck Schumer after meeting with the White House Chief of Staff and the US Treasury Secretary on coronavirus relief at the US Capitol in Washington, Aug. 7, 2020.

"In terms of Democrats getting blamed for a new aid package not getting passed, I just don't think it works that way. The public is so focused on the president and the party in power; therefore, they're responsible for inaction," said Kondik. "If I were a Republican, I would be trying to figure out what the federal government can do to best stave off economic calamity, and I would try to pass legislation to that effect."

But trying to put pandemic aid on a measure that keeps the federal government funded, likely an exceedingly complicated feat heading into late August and September -- when hurricanes and wildfires could also present more fiscal hurdles -- risks a shutdown, something Hoagland warned was possible.

"While I find it unfathomable that we could even be thinking about a government shutdown on top of everything else one month out from an election, that still is a risk," said Hoagland. "I always think that a shutdown is a pox on both parties. If this were to occur this time around, however, I think the administration and Senate GOP would take most of the blame."

MacGuineas thought the chances of a shutdown were almost nil.

"At some point, the grown-ups have to come out. We can't shut ourselves down when we have a virus that has basically already shut down our economy," MacGuineas said. "There are still some lines we won't cross."

Experts worry that a COVID-19 vaccine won’t help if not enough people are willing to get one – USA TODAY

Experts worry that a COVID-19 vaccine won’t help if not enough people are willing to get one – USA TODAY

August 14, 2020

Dr. Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security, said he's worried that any problems with Russia's newly approved COVID-19 vaccine will undermine public confidence in any vaccine for the virus. (Aug. 11) AP Domestic

While companies race to produce a safe, effective vaccine for the novel coronavirus, a crucial question remains: Will enough people take it to make a difference?

Early statistics are grim.

Only about one-third of Americans say they'd be very likely to get a vaccine to prevent COVID-19, according to a poll released last month virtually unchanged since the spring.

More people said they would get it if the vaccine were free, and others said they would sign on if there was a second wave of infections a sign that while many Americans are hesitant about a vaccine, their opinions aren't set in stone.

But convincingthem that getting a vaccine is a good idea will take effort and money. And so far, no federal dollars have been set asidefor vaccine education.

Peter Pitts oversaw the Food and Drug Administration's public outreach programs during the George W. Bush administration. Back then, as now, there was no budget.

"It was all bully pulpit stuff, and that only goes so far," said Pitts, now president and co-founder of the Center for Medicine in the Public Interest, a New York-basednonpartisan think tank.

Nowwe're in a global crisis, and funding and attention is urgent, he said. "As far as I can tell, there's no strategy on the federal or state or local levels to educate the public relative the value of a COVID vaccine specifically, or to vaccines just in general."

Two decades ago, the Human Genome Project a $3 billion effort to map every gene set aside 3% to 5% of its budget for public communication, said Emily Brunson, a medical anthropologist at Texas State University. She'd like to see the same thing done with COVID-19 vaccine development.

She and other advocates fear that if the work doesn't start soon, it'll be too late. A vaccine is likely to receive federal approval as soon as later this year.

Not everyone is hesitant for the same reasons.

People of color often have been treated poorly by the medical establishment, so they have good reason to be distrustful, said Dr. Bisola Ojikutu, an infectious disease specialist at Brigham and Women's and Massachusetts General hospitals in Boston.

Ojikutu said she's confident in the vaccine development process because of her own knowledge of the system and some of the people involved. But others will need to be convinced. "I'm concerned whether or not communities of color are going to take it," she said.

Latinos, for instance, may be afraid of authority because of the administration's aggressive immigration policies. They also often hold essential jobs with inflexible hours, which may make it challenging for them to get a vaccineeven if they want one.

Different strategies will be needed to address different causes of vaccine hesitancy, said Monica Schoch-Spana, who with Brunson co-chaired a Working Group on Readying Populations for COVID-19 Vaccinesthat recently produced a white paper.

People concerned about safety will need reassurance; people of color will need to be engaged in a process that builds trust; and people worried about government overreach will need to be heard, said Schoch-Spana, a senior scholar with the Johns Hopkins Center for Health Security.

More research will also be needed to fully appreciate this hesitation, said Lois Privor-Dumm, a senior research associate with theJohns Hopkins Bloomberg School of Public Health and anexpert in vaccine introduction.

"Understanding and respecting what people believe and what is important to them is really crucial," she said.

Then there are those who won't like any vaccine, regardless of how it was developed or what officials say.

Pitts, the former FDA official, said such anti-vaxxers shouldn't be allowed to control the public discussion around vaccines. "They are a threat to themselves, their families, their neighbors and their communities," he said.

The administration made a mistake emphasizing speed when it announced federal funding for vaccine development, vaccine advocates said. Calling the project "Operation Warp Speed" suggested to many people that it would prioritize speed over safety.

"This issue of speed is not sitting well within Black communities," Ojikutu said, suggesting the title"Operation Safe Recovery" instead.

"Everyone wants a resolution to this devastating pandemic," Ojikutu said."But in communities that have heightened mistrust towards systems, you have to focus in on how you will protect them, not on how you will develop something quickly. The piece of this that is so critical is safety."

In recent weeks, the National Institutes of Health's Dr. Anthony Fauci and other leaders of the government's vaccine development effort have repeatedly said safety is their top priority.

But first impressions linger.

"My concern is that there's be a great deal of pressure on whoever developed and tested the vaccine to get it out as quickly as possible," said Jeffrey Freed, a 59-year-old information technology consultant from Charlotte, North Carolina. "If it takes four years to do it right, then that's what we have to do."

Freed said he's not opposed to vaccines, he just wants to be convinced the science behind one is solid. Once he is and his doctor gives him the all-clear, Freed said he'll be more than willing to get a shot.

Living alone and working from home for months has left him as ready as everyone else for the coronavirus outbreak to end. "I want out," he said.

President Donald Trump and Operation Warp Speed may also have created unrealistic expectations, said Sandra Crouse Quinn, a professor and chair of the department of family science at the University of Maryland.

Unless trials go perfectly, Quinn doesn't believe a vaccine will be ready before the end of the year, as the president has promised, and even if there is one, it won't reach the average citizen for months. But by creating this expectation, Trump may be setting people up for disappointment and potentially disillusionment in the process.

"Operation Warp Speed is raising doubts about safety and cutting corners," she said.

Who delivers a pro-vaccine message will be important, Ojikutu said. If African Americans don't see people who look like them talking about getting vaccinated, they'll be far less likely to take that step themselves, she said.

She suggests enlisting Black community leaders, faith leaders and health care providers "people who have a vested interest in caring for people" in efforts to inform the public about COVID-19 vaccines.

It's not a matter of rebuilding Black confidence in vaccines, she said, because there's so little to begin with. But done right,a COVID-19 vaccination campaign could help build public faith in other vaccines.

It would be great to have Black doctors recommending vaccines, but only 2% of all doctors in the U.S. are African-American, said Dr. LaTasha Perkins, a family physician and assistant professor at Georgetown University School of Medicine.

Still, role models are essential, as is Black participation in clinical trials that will determine whether a vaccine is safe and effective.

"If you can show that the vaccine works for us, works in us and that we were part of the process, that will build trust," Perkins said.

One way to remove people's hesitancy about vaccines is to make it easy to get them, said Privor-Dumm, at Johns Hopkins. Vaccines should be low-cost or free, and given out at convenient times and locations, she said.

Someone who has to miss work to get a shot or even two, as most of the vaccines under development will require will be much more hesitant about a vaccine than someone who can get one for free, close to home at a time that works, she said.

It's also crucial to counter misinformation with accurate data about an eventual COVID-19 vaccine. There are so many myths right now "it's mind-boggling," said Theresa Horner, chair of the public health department at St. Francis University in Loretto, Pennsylvania.

"Information that can help alleviate that and provide honest answers and truths, it will certainly serve the United States well in trying to eradicate this (virus)," she said.

The bottom line is that the pandemic can't end without a vaccine that the majority of Americans are willing to take, said Dr. Lindsey Baden, director of infectious disease clinical research at theBrigham and Women's Hospital in Boston.

"If we have a successful vaccine and (only)half the people take it, we've failed."

Wednesday evening, small-cap biotech company CytoDyn announced it had asked the U.S. Food and Drug Administration to grant the companys drug, Leronlimab, an emergency-use authorization to treat mild to moderate Covid-19 cases.

The request was made after the Vancouver, Wash.-based company announced promising data from a Phase 2 Leronlimab drug trial.

Thats good news. But following the ins and outs of therapy development can be difficult in any environment. Investors typically arent doctors. Covid-19 doesnt make it any easier. Investors these days are tracking many antiviral drugssome of which were designed for other virusesas well as several vaccine candidates.

Vaccines, of course, prevent people from contracting the virus. Antivirals treat the disease. Both are important to defeating Covid.

Leronlimab is an antiviral medication that was originally developed for HIV treatment. Its a humanized IgG4 monoclonal antibody that inhibits the ability for a virus to enter a cell. CytoDyn (ticker: CYDY) started testing Leronlimb on Covid-19 patients earlier in 2020.

What the company said Wednesday is that patients given shots of Leronlimb improved more than patients given placebos. The results were statistically significant.

CytoDyn is a $2.1 billion development-stage biotech without sales. Gilead Sciences (GILD) is an $85 billion biotech generating more than $22 billion in annual sales. Gileads Remdesivir is another antiviral medication that showed promise in clinical trials. The FDA granted Remdesivir emergency-use authorization to treat severe cases in May. Antiviral therapies are also in the works at Eli Lilly (LLY), GlaxoSmithKline (GSK), and Vir Biotechnology (VIR).

Regeneron Pharmaceuticals (REGN) is developing a cocktail of antibodies for Covid-19 treatment. Earlier this week, Canaccord Genuity analyst John Newman wrote that Phase 3 data for the cocktail could be ready later this year.

Later this year is also the time frame for data from important Phase 3 vaccine trials. Phase 3 is typically the last phase of clinical testing and is designed to demonstrate efficacy.

Russia made headlines earlier in the week announcing their vaccine was ready. But, in U.S. terms, their vaccine has just exited Phase 1 and 2 trials.

GlaxoSmithKline, Pfizer (PFE), Oxford University, Moderna (MRNA) and Novavax (NVAX) all have vaccine candidates in Phase 3 testing. It has been a while since those entities updated investors, but enrollment should be wrapped up soon. Each of those companiesand the universityis recruiting about 30,000 patients in the final trial.

Covid-19 health-care stocks have had a wild 2020. CytoDyn stock actually dropped 8.5% following the conference call. The stock is down 15% for the week, despite positive data. Still, shares have gained more than 300% year to date, far better than the comparable gains of the S&P 500 and Dow Jones Industrial Average over the same span.

The stocks mentioned above are up 465% year to date on average. Novavax is up the most at more than 3,200%. Glaxo is the weakest of the bunch, falling 12.3% year to date.

Corrections & Amplifications

CytoDyn is based in Vancouver, Wash. An earlier version of this article incorrectly said it was a Canadian company.

Andrew Lloyd Webber gets experimental COVID-19 vaccine: ‘Ill do anything’ for theater – Asbury Park Press

Andrew Lloyd Webber gets experimental COVID-19 vaccine: ‘Ill do anything’ for theater – Asbury Park Press

He is not throwing away his shot.

One day after announcing that he would be taking part in a COVID-19 vaccine trial, legendary composer Andrew Lloyd Webber said that he had received the experimentalimmunization.

"Just completed the Oxford Covid-19 vaccine trial. Ill do anything to get theatres large and small open again and actors and musicians back to work," he wrote on social media on Thursday.

In this Jan. 28, 2018 photo, Andrew Lloyd Webber arrives at the 60th annual Grammy Awards at Madison Square Garden in New York. A new permanent exhibit opening Tuesday, June 11, 2019, offers visitors an Instagram-ready chance to put on costumes and sing some of Broadway's most famous show tunes, but also a taste of what's going on backstage, from controlling fog to switching on lights. While it's billed as "The Ultimate Broadway Experience," the truth is it's more a Lloyd Webber experience, featuring only props, music and characters from the theater icon's work: "The Phantom of the Opera," "Joseph and the Technicolor Dreamcoat," "Evita," "Sunset Boulevard," and "Cats."(Photo: Evan Agostini/Invision/AP)

The post accompanied a photo of himself sitting in a chair next to a medical professional who is preparing to give him the shot. Lloyd Webber is wearing a black T-shirt emblazoned with "Save Our Stages," the same hashtag he ended his post with.

On Facebook he tagged the National Independent Venue Association, which works at "securing financial support to preserve the national ecosystem of independent venues and promoters," according to its mission statement. The group reposted Lloyd Webber'smessage and added a thank you note.

On Wednesday, Lloyd Webber announced that he was taking part in thetrial.

"I am excited that tomorrow I am going to be vaccinated for the Oxford Covid 19 trial. Ill do anything to prove that theatres can re-open safely," he tweeted.

Lloyd Webber, composer of "The Phantom of the Opera," "Cats,""Evita," "School of Rock" and other musicals produced both in the West End and on Broadway, has been vocal about the reopening of London's theaters.

A few weeks ago, after "Phantom of the Opera"producer Cameron Mackintosh said that the pandemic has caused the London and UK touring productions of the show to permanently shut down, Lloyd Webber responded: As far as Im concernedPhantomwill reopen as soon as is possible.

In the United States, Broadway shows have been shut down since March 12, and are officially closed at least through the new year, though most expect the shutdown to last longer than that.

Lloyd Webber also has been busy engaging with fans on social media and bringing experiences to at-home audiences with his "Composer in Isolation" video series and the introduction of "The Shows Must Go On," which made professional recordings of musicalsavailable on YouTube for a weekend at a time.

How close are we to a safe, effective COVID-19 vaccine? – The Hub at Johns Hopkins

How close are we to a safe, effective COVID-19 vaccine? – The Hub at Johns Hopkins

August 14, 2020

ByHub staff report

The COVID-19 vaccine is on track to become the fastest-developed vaccine in history, but that doesn't mean critical steps are being skipped.

Ruth Karron, who leads the Center for Immunization Research at the Johns Hopkins Bloomberg School of Public Health, is one of the top vaccine experts in the world, serving on vaccine committees for the U.S. Centers for Disease Control and Prevention, the World Health Organization, and the U.S. Food and Drug Administration.

She recently spoke with Josh Sharfstein, professor and vice dean for public health practice and community engagement at the Bloomberg School, about where things stand in the development of a COVID-19 vaccine and how that process will unfold in the months ahead. This conversation is excerpted from the July 31 episode of the Public Health on Call podcast.

There are some very encouraging developments. We have a few vaccines now that will go into Phase 3 clinical trials, also known as efficacy trials. That means that those vaccines have passed certain goalposts in terms of initial evaluations of safety and immune response such that they can be evaluated in larger trials.

We know that these vaccines are promising, but we don't yet know if they are going to work. That's what the purpose of an efficacy trial isas well as to provide a broader assessment of safety of the vaccine in a large number of people.

They involve large numbers of people: In these particular trials for COVID vaccines, there are going to be about 30,000 people enrolled per trial. Individuals are given a vaccine, and then they are followed both to make sure that the side effects from the vaccine are acceptable and to see whether they develop a SARS-CoV-2 infection along with some symptoms.

These are placebo-controlled trials, meaning that some individuals will get a COVID vaccine and some will get a placebo. Then the rates of disease will be compared in the people who got placebo and the people who got the vaccine to determine the efficacy of the vaccine.

The FDA recently issued guidance to vaccine manufacturers about the development of COVID vaccines stating that a vaccine would need to be at least 50% effective. This means that an individual who was vaccinated would be 50% less likely to get COVID diseaseor whatever the particular endpoint is that's measured in the trialthan individuals that weren't vaccinated.

This is a reasonable goal for a number of reasons. Typically, the more severe a disease is, the better chance a vaccine has of preventing that disease. So a vaccine that's 50% effective against mild COVID diseasewhich might be the endpoint that's measured in a clinical trial, or any evidence of COVID infection with any symptom, which is how a lot of trials are designedmight be more effective against severe disease.

When you have a disease that's as prevalent as COVIDand if we think about what the U.S. has experienced in the past several months in terms of severe disease and deatheven if we were only able to cut those numbers in half, that would be a major achievement.

Time will tellthe short answer is that we don't yet know. We haven't yet had the opportunity to follow individuals for very longthe very first people who got the very first vaccine were immunized in March and it's only July. So we don't know very much about the durability of the immune response in people.

Our hope would be [that protection would last] at least a year or more, and then people might need boosters.

It's also possible that a vaccine might not entirely protect against mild disease. So you might actually experience mild disease and then have a boost in your immune response and not suffer severe disease. From a public health perspective, that would be completely acceptable. If we turned a severe disease not into "no disease" but into mild disease, that would be a real victory.

Every person who is enrolled in the trial will complete information about the kinds of acute symptoms that you might expect following an infection. People will need to provide information about swelling, redness, tenderness around the injection site, fever, and any other symptoms they might experience in the three to seven days following vaccination.

More long term, people will be looking to make sure that when COVID disease is experienced, there's not any evidence of more severe disease with vaccination, which is known as disease enhancement.

There was a lot of discussion as these vaccines were being developed of a concern about disease enhancement. This is based on some animal modelsnot with SARS-CoV-2, but with other coronaviruses. We haven't seen any evidence of enhanced disease thus far and there are a number of scientific reasons why we don't think it should occur with these vaccines. But, of course, it's something we would still watch for very carefully just as with any other safety signal.

There are a couple of things to mention about that, and one is that individuals with these trials will be followed for a year or longer. It may be that a vaccine is either approved for emergency use or licensed before all of that long-term follow up is completed. Nevertheless, companies will be obligated to complete that follow up and report those results back to the FDA.

Director of the Center for Immunization Research

It's important to enroll older adults in these studies. All of these large efficacy trials will be stratified so there will be some younger adults and some older adults enrolled.

In addition, it's very likelyand this would not just happen with COVID vaccines, but whenever the FDA licenses vaccinesthat there is an obligation for post-licensure assessments. If a COVID vaccine is licensed, the companies will work with the FDA to determine exactly what kind of post-licensure safety assessments will need to be done.

I think it will be important to enroll older adults across an age span. A 65-year-old is not the same as an 85-year-old. Also, a healthy older adult is not the same as a frail older adult who might be living in a care facility.

We'll need some information about diverse elderly populations in order to think about how to allocate vaccines. There may also be other alternatives for older adults if they don't respond well to vaccines. There's a lot of work going on on development of monoclonal antibodies as an alternative for groups that don't respond well to vaccines such as elderly, frail adults.

It's critically important that we have racial and ethnic diversity.

We know that COVID causes increased rates of severe disease in Latinx and Black populations and in Native American populations. We will certainly want to be able to offer these COVID vaccines to these high-risk populations and encourage their use. But we need to know how well these vaccines work in these populationsif different vaccines work differentlyso that we can offer the most effective vaccines.

It's really important to engage those communities in a number of ways. One way is to engage local leaders early in the process. Lay leaders and leaders of faith communities can have focus groups to find out what their concerns are and how those can be allayed.

I think a very important issue that has been raised by some people who might potentially volunteer for some of these trials has to do with eventual access. People want to have some sense that if they participate in a trial, not only might they have access to the vaccine at the end of that trial, but their families and their communities would, too. Ensuring access among these high risk and vulnerable communities is really critical.

That's absolutely the case. It's great that you brought up the "without charge" piece, too, because a vaccine that's made available but costs something to the individual may not be used. Particularly for people who don't have health insurance or people who are undocumented. It has to be broadly and freely available.

I've done some work in this areaparticularly with Ruth Faden and Carleigh Krubiner in the Berman Institute of Bioethicsspecifically related to ensuring that pregnant women are considered and included in vaccine development and implementation for vaccines against epidemic and pandemic diseases.

When thinking about trials, there needs to be a justification for excluding pregnant women from trials rather than a justification for including them. The justification often isand certainly is the case with these early COVID vaccinesthat we don't know enough yet about the vaccine or the vaccine platform or the safety of the vaccine to do a study in pregnant people.

With the mRNA vaccine, for example, [the type of vaccine being considered for COVID-19] we don't currently have a licensed mRNA vaccine. It's a new platform and we're just learning about the safety of that platform so it wouldn't have been appropriate to include pregnant women in the early stage trials.

But these 30,000-person studies are going to be really big studies. They will certainly enroll people of child-bearing potential. And even though there's what we call an exclusion criterionwomen are not supposed to be pregnant at the time they are enrolled, and usually women of child-bearing potential will take a pregnancy test prior to enrollment and immunizationwe know from previous experience that it's quite likely that some women will become pregnant in the months immediately following immunization. It happens quite frequently. So, it's important for companies and the government to anticipate that this will be the case and to think about how they will systematically collect data from women who do become pregnant during these trials.

It's not that the data needs to be interpreted cautiouslybecause pregnant women aren't being formally randomized and we don't have that kind of trial designbut there are things that could be learned and it's important to think now about how to collect those data. It's also important to think about how pregnant women could be directly included in both trials and deployment later down the road.

Yes. I think we need to learn a bit more about the epidemiology in children. Fortunately, children don't seem to suffer from acute COVID disease at the rates that adults do. But we need to learn more about that and we also need to learn from our trials in adults before we make decisions about how and whether children will be included in vaccine trials.

The best vaccine in the world won't work if it isn't used. Use has two parts to it: One is availability and access, and the other part is acceptance.

We need to think about what kind of infrastructure we should be planning now for what we're going to need to deliver this vaccine. We'll set priorities; certainly not everyone is going to get a vaccine all at once. But certainly, over time we will expect that all adults will receive the vaccine and perhaps children. So we'll need to have systems in place that can deliver the vaccine. At the same time, we need to make sure that the vaccine is acceptable. We need to communicate the importance of vaccination to the public and address their concerns so that we can not only be able to deliver vaccines, but have those be accepted by the public.

Yes. If you think back to the fact that in January, we barely knew what this virus was, and here we are, seven months later, embarking on efficacy trials, it's really a remarkable accomplishment. We have a lot to do yet, but in the time that we're assessing the efficacy of these vaccines and making sure that they can be delivered to the public, people really need to stay safe and do all the things we've been encouraging them to do all along.

But we are well on our way to developing vaccines not only for people in the U.S., but for people all over the world.

IT IS August 2021, and the moment the world has been waiting for has finally arrived. After many false dawns, a vaccine against covid-19 has passed all the tests and is ready to be rolled out.

It has been an arduous journey, but at last vaccine manufacturers around the world are cranking out thousands of doses a day. The end of the pandemic is on the horizon.

But this isnt the end. It isnt even the beginning of the end. There are more than 7.5 billion people in need

Vaxart Positioned to Further Advance Oral COVID-19 Vaccine; Analyst Says Buy – Yahoo Finance

In the race to develop a COVID-19 vaccine, the contenders arent about to cross the finish line just yet. As the deadly virus resurfaces in several countries, the world is anxiously waiting to see which name will be the first to bring the coveted solution to market. Already underway for months now, its still anyones game in this battle of the ages.

Who is emerging as a likely winner? If you ask 5-star analyst Vernon Bernardino, of H.C. Wainwright, of the 165-plus vaccine candidates (38 in clinical-stage testing) in development, Vaxarts (VXRT) chances are looking pretty good.

Based on the companys Q2 2020 corporate update, it has reached multiple milestones that position it at the front of the pack. That being said, the analyst cites one accomplishment in particular as deserving of a major shoutout.

Bernardino believes its selection to take part in a non-human primate (NHP) challenge study organized and funded by Operation Warp Speed (OWS) is the most notable of these milestones. Highlighting the candidates broad potential in the battle against the virus, the analyst argues the Street might just be underestimating the role it could play.

Expounding on this, the H.C. Wainwright analyst stated, ...our positive view of Vaxarts oral COVID-19 vaccine program advancing was bolstered by its selection for OWS participation, as this, in our opinion, represents recognition by BARDA that oral vaccines tested by Vaxart for other infectious diseases, such as influenza, norovirus and respiratory syncytial virus (RSV), point to an oral vaccine as a potentially important approach to vaccinating what is likely to be more than 100 million people in the U.S., and perhaps billions of people globally, most of which have no existing immunity to SARS-CoV-2.

The implications of the OWS selection go even further. NHPs are a rare resource for conducting preclinical studies, with only seven primate research centers able to perform NHP studies. In addition, the number of subjects is limited and the waiting lists are long.

Story continues

Given that the task of conducting the NHP challenge study has been assigned to the U.S. National Institutes of Health (NIH), its unclear what the timeline for completion and release of results will be.

Nonetheless, Bernardino remains confident in VXRTs prospects. ...in line with the pace of progression of competitor COVID-19 vaccine candidates, we expect the NHP study with Vaxarts vaccine to be given high priority and be conducted quickly. We look for results in late Q3 2020 to be a positive catalyst, he explained.

Accordingly, Bernardino keeps a Buy rating on the stock. The positive assessment also warrants a substantial increase to the price target, which moves from $7 to $17. This target suggests shares could jump 87% in the year ahead. (To watch Bernardinos track record, click here)

VXRT has kept a relatively low profile, as only one other analyst has thrown an opinion into the mix. The additional bullish call means that the stock gets a Moderate Buy consensus rating. At $19.50, the average price target is more aggressive than Bernardinos and implies 114.5% upside potential. (See Vaxart stock analysis on TipRanks)

YERUSHALAYIM -

Thursday, August 13, 2020 at 10:24 am | ""

Three coronavirus patients treated at Hadassah Hospital in Yerushalayim with an experimental passive vaccine treatment by administering Immunoglobulin G (IgG) have fully recovered, giving hope for other patients, the hospital said Thursday.

The three were treated as part of a clinical study, jointly conducted by Hadassah Hospital and the public biomedical company Kamada.

For three months, despite the initial opposition of the former director general of the Health Ministry, Hadassah has been collecting plasma donations from coronavirus patients, Hadassah head Prof. Zeev Rotstein said, with the aim of producing a treatment for severely ill patients.

Specifically, the plasma was collected with the help of the chareidi chessed organization Yad Avraham and the chareidi community, Hadassah hospital noted. Patients who tested negative for the coronavirus twice and showed high levels of antibodies in their blood were asked to donate plasma.

Those who develop any virus, including the coronavirus, develop special antivirus proteins or antibodies in their plasma, which can help sick patients cope with the disease.

The plasmas, collected from the recoverees, were processed by the Kamada company at Kibbutz Beit Kama in the Negev for an IgG-based antibody treatment for patients in severe condition, patients who suffer from pneumonia due to the virus.

Kamada produced what it calls its anti-SARS-CoV-2 plasma-derived immunoglobulin (IgG) product.

The first three patients who recovered as part of the clinical study demonstrated a rapid clinical benefit and have been discharged home from the hospital.

Hadassah administered the worlds first passive vaccine to a seriously ill patient, a young woman with underlying illnesses whose CT results showed completely white lungs, and all known treatment methods have not affected her condition.

Several hours after receiving the treatment, the patients condition appears to have stabilized, giving room for cautious optimism.

Kamada updated in its reports that the virus neutralization test showed encouraging neutralization activity of the product and that the company plans to further test the antibody product as a potential preventative treatment for COVID-19 on healthy volunteers at risk.

Prof. Rotstein said that the vaccine, which could also be called a medicine, is being targeted toward COVID-19 patients whose situation is worsening and need a booster to fight the disease. However, it may also be used prophylactically in cases where a high-risk patient contracts coronavirus and the hospital wants to stop the diseases progression.

It is evident that the Hadassah team is very satisfied with the clinical research, said Dr. Assa Kessler, a doctor in the hospitals coronavirus unit. She said the plasma is being distributed to COVID-19 patients who develop pneumonia and for now, we are very encouraged by the results.

Rotstein said that these preliminary results should raise hope in Israel and around the world.

COVID-19 vaccine may be less effective in obese people, experts warn – ABC News

COVID-19 vaccine may be less effective in obese people, experts warn – ABC News

August 14, 2020

As the world waits for a COVID-19 vaccine, concerns are already rising that it may not work in obese patients, arguably one of the groups that needs it most.

More than 1 in 3 Americans is obese, and the Centers for Disease Control and Prevention has said that obese people are among the groups more likely to get sick and die of COVID-19.

"We know from other vaccines that have been tested in obese populations that these individuals don't respond as well to these vaccines," said Dr. Matthew B. Laurens, a lead investigator at the University of Maryland School of Medicine for one of the United States' most advanced coronavirus vaccine trials by Moderna Therapeutics.

Research has long shown that vaccines against viruses like influenza and hepatitis B, as well as other disease-causing organisms like tetanus and rabies, are not as effective in obese adults compared to their thinner peers.

Evidence of this phenomenon goes as far back as 1985, when hundreds of hospital employees in North Carolina were vaccinated against hepatitis B and then studied to see how their immune systems responded. Researchers found that the vaccine was twice as likely to fail -- meaning it did not provide adequate protection against hepatitis B -- in employees with a higher body mass index compared to their colleagues with lower BMIs.

In 2017, researchers at the University of North Carolina, Chapel Hill reported similar findings in patients getting their yearly flu shot. In their study of over 1,000 participants, they found that obese adults were twice as likely to develop influenza or an influenza-like illness -- despite having been vaccinated against the virus -- compared to non-obese adults.

With 42.4% of the American population being classified as obese, and research identifying obesity as a major risk factor for COVID-19 infection and severe complications from the disease, this is giving some experts reason for pause.

A woman receives a COVID-19 vaccination from nurse Jose Muniz as she takes part in a vaccine study at Research Centers of America on Aug. 7, 2020, in Hollywood, Fla.

"We recognize that while we're developing a vaccine for COVID-19, it might not work in all populations, including those who are obese. So that's a concern," said Laurens.

It's not entirely clear to experts why vaccines don't seem to work as well in obese patients, but there are a number of theories.

One thought is that the typical one-inch needle routinely used for immunizations is not long enough for use in obese adults. This is because the fat layer under the skin may be thick enough that the needle can't reach the underlying shoulder muscle, where the vaccine liquid needs to be deposited to have its best shot at working.

Another theory is that obese adults, because of their increased body mass, may actually need a bigger dose -- or even a booster dose -- of the vaccine to properly ready their immune system to fight off the virus.

A third theory has to do with how obese patients' immune systems work.

According to Dr. Leonard Friedland, the vice president and director of Scientific Affairs and Public Health for GlaxoSmithKline Vaccines, "Obesity triggers a chronic inflammatory state in humans." This constant, low-level inflammation could be what's blocking some vaccines from working as well as they do in thinner patients.

"It's a real issue," said Friedland.

But could the coronavirus vaccine be different and provide equal protection for both the obese and the non-obese?

"We don't know. I think you could say it's possible. The new technology is different," said Laurens, referring to the novel mRNA technology being used in the coronavirus vaccine trial he's currently spearheading.

An undated stock photo depicts a doctor administering a vaccination to an overweight patient.

For now, perhaps the only way to know for sure whether the vaccine will work in the obese is to include them in large phase 3 trials -- the last step before authorization from the Food and Drug Administration.

"It's important to enroll obese people, because they are likely to have associated chronic illnesses, and you really get to see if the vaccine helps those highly at-risk people," said Dr. Arthur L. Caplan, the Drs. William F. and Virginia Connolly Mitty professor of bioethics at the New York University Langone Medical Center.

Historically, obese people have been largely excluded from vaccine trials, because of these chronic illnesses, like diabetes and high blood pressure.

Coronavirus vaccine developers, however, are now attempting to combat this disparity by actively enrolling obese patients in their clinical trials.

"We think it's important to develop a vaccine that is going to work for everyone," said Laurens. "That's why we're trying to be as inclusive as possible in the phase 3 studies -- so that we can learn more about how to protect particularly the vulnerable populations, including the obese."
