COVID-19 vaccine 2nd dose and booster drive to be held in Edwards – WJTV

January 4, 2022

JACKSON, Miss. (WJTV) - Governor Tate Reeves (R-Miss.) talked to WJTV 12 News in a one-on-one interview ahead of the 2022 Legislative session. The topics included COVID-19, teacher pay raises, and medical marijuana.

A medical marijuana plan is likely to be put into law during the regular session, with or without the governors blessing. Reeves recently said he will try to persuade some Republicans to stand with him if he vetoes a bill.

Woman arrested for illegally injecting teen with COVID-19 vaccine – New York Post

January 4, 2022

A Long Island woman was arrested for illegally injecting a 17-year-old boy with a COVID-19 vaccine at her home without the teens parental consent, police said Saturday.

Laura Russo, 54, who is not a doctor or authorized to administer vaccines, was busted for the New Years Eve incident at her Sea Cliff residence, according to Nassau County police.

The authorities were notified after the teen left Russos home and told his mother about the jab, according to cops.

Russo was charged with unauthorized practice of a profession and released on a desk appearance ticket.

She is due to appear in court on Jan. 21, police said.

What is Covaxin, the COVID vaccine not approved in the US? – fox4kc.com

January 4, 2022

Dr. Anthony Fauci last week addressed Covaxin, a COVID-19 vaccine made in India that has not been approved in the U.S. but is finding its way into the social media feeds of the American public.

We have enough vaccines, the best vaccines available, in the United States, Fauci, the chief medical advisor to President Joe Biden, said in response to a question about Covaxin during his Thursday interview with Adrienne Bankert on NewsNations Morning in America.

When asked about the Covaxin approval timeline, Fauci indicated the interest was surprising.

Im puzzled by that question, he said about Covaxin. We have more vaccines than we need right now. We just need the people to get vaccinated with the vaccines that we have. The mRNA vaccines are vaccines that are desired by everyone else in the world. So we have what we need; we need to use it.

So why the interest in Covaxin? How does it compare to the vaccines currently available in the United States?

Covaxin is different from the Pfizer-BioNTech and Moderna vaccines in how they are made. Pfizer and Moderna are mRNA vaccines, a relatively new approach that teaches our cells how to make a protein that triggers an immune response inside our bodies, according to the CDC.

Covaxin takes a more traditional approach. Its made by using a disabled form of the COVID-19 virus to stimulate the immune system. This is similar to Johnson & Johnsons approach to the vaccine.

Covaxin was developed and manufactured in India by Bharat Biotech, a partner of the publicly traded company Ocugen. It was developed with funding from the National Institutes of Health and requires two shots taken 28 days apart.

Covaxin was awarded an emergency-use listing by the World Health Organization in November, which further validates the vaccine.India also announced Monday that it will be the only shot available to children aged 15 to 18 when inoculations begin for that age group next week.

The interest in Covaxin in the U.S. is also being driven by investors whose investment in Ocugen would likely skyrocket if the vaccine was approved by the U.S. Food & Drug Administration.

The question about Covaxin asked in the NewsNation interview was one of dozens submitted through a loosely coordinated campaign to ask Fauci about the Indian vaccine.

Any type of support for Covaxin is amplified by its supporters, including one on Thursday by professional tennis legend Jimmy Connors.

The Indian Council for Medical Research, which helped develop Covaxin, says the vaccines approach is like a Bruce Lee assault because it targets three potentially fatal areas at the same time.

It was created with an adjuvant developed by the NIH, technology that has been lauded by Fauci.

I am pleased that a novel vaccine adjuvant developed in the United States with NIAID support is part of an efficacious COVID-19 vaccine available to people in India, Faucisaid.

But theres little data to support that its better than the Pfizer and Moderna vaccines. COVID-19 infections are decreasing in India. However, the country has reported a swift rise in omicron cases.

Research compiled by The Economist shows that both Pfizer and Moderna did better at preventing infection and hospitalizations than Covaxin against the delta variant.

Covaxin does have one advantage: It doesnt require the ultra-cold storage of the American vaccines, which is expensive. That makes Covaxin more attractive to poorer, developing countries.

Health expert Jammi N Rao told Quartz India in early December that to date, there is no reliable evidence that they necessarily offer wide-ranging protection against new variants that result from multiple points of genetic mutation.

I can only speculate that it comes not from hard science but from a desire to project Covaxin as better than any other vaccine because it is an indigenously developed vaccine, Rao told Quartz. It is therefore understandable why many people would want this theory to be true, but it is not the way of science to promote a theory because it is convenient.

Fauci mistakenly said on Morning In America that Covaxins manufacturer, Bharat, had not applied for FDA approval. But his office followed up later that day with this statement: Bharat Biotech, the company that has developed Covaxin, has applied to the FDA for an emergency use authorization (EUA) for their vaccine. The FDA is currently evaluating the data and no decision has been made.

The FDA looks at the data and if the data are in order and give you a good scientific rationale to approve it, the FDA will approve it, Fauci also said in the Morning in America interview. There are no interventions that are not being approved for reasons other than theyve either not been submitted for approval or the data are not strong enough to warrant approval.

Fauci also said he did not think the United States needed another vaccine. Instead, he said, it needed to get more people vaccinated with the vaccines currently approved.

Its not alternative. Its another vaccine, Fauci said of Covaxin in his appearance on Morning in America. We dont need another vaccine.

When asked about its FDA application, a spokesperson for Ocugen gave NewsNation the following statement:

COVAXIN demonstrated its broad-spectrum safety and efficacy in a large, multicenter, phase 3 clinical trial of more than 25,000 people, where it was proven to be 93.4% effective at preventing severe COVID-19 disease, reducing hospitalizations, and 77.8% effective against the overall disease. In a pediatric, immunobridging trial involving children, aged 2-18 years, the vaccine was shown to generate a neutralizing antibody response against the whole SARS-CoV-2 virus and antibody responses against 3 different viral proteins S1, NP, RBD equivalent to what was seen in the phase 3 adult efficacy trial. There were also no severe adverse events reported, such as hospitalizations, pericarditis, myocarditis or blood clots, demonstrating a compelling safety profile. Ocugen submitted a pediatric Emergency Use Authorization (EUA) based on these data to the FDA on Nov. 5, 2021, so that parents and healthcare providers in the U.S. can have a safe and effective vaccine option for their children in the effort to end the coronavirus pandemic.

More than 200 Marines separated for refusing COVID-19 vaccine – ConchoValleyHomepage.com

January 1, 2022

(The Hill) More than 200 Marines have been removed for refusing to comply with the Pentagons COVID-19 vaccine mandate.

Capt.Andrew Wood, a Marine Corps spokesperson, said in an emailed statement that 206 Marines have been separated to date for not getting vaccinated.

The new numbers come as the military ramps up discipline for service members who refuse to get vaccinated.

Earlier this month, the Marines announcedthat 103 service membershad been separated for refusing to comply. Last week, that number rose to 169.

The fiscal 2022 National Defense Authorization Act, whichPresident Bidensigned into law on Monday, stipulates that service members who are discharged for not complying with the mandate receive at least a general discharge.

Defense SecretaryLloyd Austinmandated vaccinations for the military in late August, but each service is responsible for enforcing its own deadlines. The deadline for active-duty Marines to be vaccinated was Nov. 28, and the deadline for reservists to comply was Tuesday.

Overall, 95 percent of themore than 182,000 active-duty Marines are at least partially vaccinated, while 94 percent are fully vaccinated, Wood said in the statement. These numbers are on par with the vaccination rate from earlier this month.

However, the vaccination rate for reservists increased, with at least 86 percent of reservists at least partially vaccinated and 83 percent fully inoculated.

The Marine Corps is still tracking 1,007 approved administrative or medical exemptions, Wood added.

However, the number of requests for religious accommodations has risen to 3,247. Of these, the service has not approved any of the 3,115 requests that it has processed.

Overall, more than 1.9 million service members have either been partially or fully vaccinated, according to data available from theDepartment of Defense.

Sinovac COVID-19 shot with Pfizer booster less effective against Omicron – study – Reuters

January 1, 2022

Dec 31 (Reuters) - Sinovac's two-dose COVID-19 vaccine followed by a booster Pfizer-BioNTech shot showed a lower immune response against the Omicron variant compared with other strains, according to a study by researchers.

The study, which has not been peer-reviewed yet, was conducted by researchers from Yale University, the Dominican Republic's Ministry of Health and other institutions.

The Sinovac (SVA.O) two-dose regimen along with the Pfizer (PFE.N) shot produced an antibody response similar to a two-dose mRNA vaccine, according to the study. Antibody levels against Omicron were 6.3-fold lower when compared with the ancestral variant and 2.7-fold lower when compared with Delta.

Register

Akiko Iwasaki, one of the authors of the study, said on Twitter that CoronaVac recipients may need two additional booster doses to achieve protective levels needed against Omicron.

The two-dose Sinovac vaccine alone did not show any detectable neutralization against Omicron, according to the study that analysed plasma samples from 101 participants in the Dominican Republic.

A study from Hong Kong last week said that even three doses of the Sinovac vaccine did not produce enough antibody response against Omicron and that it had to be boosted by a Pfizer-BioNTech shot to achieve "protective levels." read more

Sinovac's CoronaVac and state-owned Sinopharm's BBIBP-CorV vaccine are the two most-used vaccines in China and the leading COVID-19 shots exported by the country. Hong Kong has been using the Sinovac and Pfizer-BioNTech vaccines.

As COVID-19 hospitalizations among kids increase, low flu vaccination rates add another layer of concern – The Philadelphia Inquirer

January 1, 2022

A low rate of flu vaccinations among children this year threatens to exacerbate overcrowding problems at hospitals already contending with a surge in COVID-19 cases.

Just over a third of Philadelphia children ages 6 months to 17 years have received their flu vaccines so far, compared to close to half in December last year and more than half in December 2019. About a quarter of the citys children ages 5 to 11 have been vaccinated for COVID-19.

Statewide, half of children have received the flu vaccine as of Dec. 4, the Centers for Disease Control and Prevention reported, compared to more than 55% at this time in 2020 and 2019. In New Jersey, about 54% of children have been vaccinated, slightly below the vaccination rates the past two years. The CDC has not released adult flu vaccination rates by state for this flu season.

While the flu is less serious than COVID-19, it can lead to severe illness and even death in the elderly and in children, particularly those 5 and younger. It killed almost 200 children in 2019. Children with asthma, pulmonary, and neurological conditions are also susceptible to serious flu infections. Eleven Pennsylvanvians have died of the flu this season, the state health department has reported. New Jersey reports only pediatric flu deaths, with none so far this season.

For most healthy teens and adults, even a routine case of the flu can be debilitating.

True influenza is a miserable illness, said Cheryl Bettigole, Philadelphias health commissioner. Shaking chills, a fever of 104 degrees, in bed for days. ... We dont want this.

Flu infections typically begin surging in December and continue through March. Each year, flu infects tens of millions, and annual U.S. deaths from 2010 to 2019 ranged from 12,000 to 52,000. Influenza vaccines are widely available at doctors offices, pharmacies, and city health clinics.

In Pennsylvania so far, 17,335 influenza cases have been confirmed, with cases highest in the southeast and northeast parts of the state. New Jersey reported 6,079 cases so far, the highest influenza activity reported for this time of the year since the 2017/2018 season.

READ MORE: Dont forget the flu. Its still on the rise.

Hospitals, including pediatric facilities, are concerned about an influx of flu patients this year as they grapple with COVID-19 hospitalizations, local health officials said. Childrens Hospital of Philadelphia has had 10 to 25 COVID-19 inpatients a day in December, said Ron Keren, CHOPs chief medical officer, compared to five to 10 daily last month. COVID-19 hospitalizations among those 17 and younger have increased 2% from the week ending Dec. 28 compared to the week before. In New Jersey, those hospitalizations are up 67% over the same time period. Meanwhile, infections from the highly transmissible omicron variant are taking hospital staff out of the workplace.

If we superimpose on that a big wave of influenza hospitalization it could create a real problem for us, Keren said.

In Philadelphia, more than 65,600 people have received flu vaccines this season, tens of thousands fewer than at the same time over the past two years.

In a reversal of the citys pattern for COVID-19 vaccine administration, rates of flu vaccination among Black and Latino populations are higher than among white Philadelphians. That could be because providers have offered flu vaccines alongside COVID-19 vaccines, Bettigole said, and in recent months most of the citys COVID-19 shots have gone to people of color.

Health officials said they didnt believe the lower rates indicated that the anti-vaccine sentiment leading a significant minority of Americans to refuse COVID-19 inoculation is spreading to other kinds of vaccines. Routine vaccinations for children, the Philadelphia Department of Public Health reported, are roughly similar this year to pre-pandemic levels.

As far as Ive been able to tell, it seems to be people are just so overwhelmed with everything else, Bettigole said. I think its just that people are ... not getting motivated to do this thing they know they need to do.

Last year, COVID-19 restrictions on travel and socializing meant flu season was virtually nonexistent. That experience, though, may have made people less aware of influenzas annual cost. As of late November, the most current data available from the CDC, flu vaccines administered by pharmacies and doctors offices nationally were down 7% compared to 2019. The decline was even greater compared to 2020. Like children, vaccination rates among those with children are much reduced this year, too.

My initial thoughts from just talking to a few people, without having flu last year, I think theyre just simply not as aware of the threat the influenza poses, said Andrew Pekosz, a virologist at the Johns Hopkins Bloomberg School of Public Health.

READ MORE: Penn expert raises questions about this years flu shots but says to get one anyway

The flu vaccine doses this year are less effective against one of the four types of influenza it is designed to prevent, and that strain, H3N2, appears to be the dominant one, the CDC reported. That flu strain is associated with more severe infections, Pekosz said. But that doesnt mean it isnt worth getting vaccinated. As with COVID-19 vaccines, even if the shot doesnt stop infections, it does protect people against more serious illness.

Even when its not completely matched, it has been shown to reduce severe disease in a way thats very similar to what were talking about now with delta variant and the omicron variant, Pekosz said. Its clear that it reduces severe disease, gives your immune system a little bit of a head start.

Winning by a nose in the fight against COVID-19 | TheHill – The Hill

January 1, 2022

We are still in the early days of the age of omicron, and there is much that we do not know about this variant of COVID-19. But we do know that it is more transmissible than other variants and that it arose in a part of the world where only a small percentage of the population wasvaccinated.

In the film Contagion, for which Larry Brilliant and W. Ian Lipkin were scientific advisers, Centers for Disease Control and Prevention (CDC) scientist Ally Hextall, played by actor Jennifer Ehle, injects herself with an experimental vaccine against the pandemic virus MEV-1. In a later scene, CDC Director Ellis Cheever, played by Laurence Fishburne, gives a child the intranasal vaccine that ultimately ends thepandemic.

We recommended the filmmakers use an intranasal vaccine because it would be easy to manufacture worldwide, distribute and deliver. In addition to reducing barriers to access, it would also be more effective at preventing infection by providing what is called mucosal immunity, an immune blockade in the nose, where the virus first enters the body.

However, despite the many advantages of intranasal vaccines, only eight of 137 vaccines listed in clinical trials by the World Health Organization (WHO) areintranasal. All the COVID-19 vaccines approved for use by the WHO, including those that have received emergency use authorization by the United States Food and Drug Administration, require intramuscular injection. Clinical trials confirm that these vaccines reduce the risk of severe disease in those who take them. What they have not done, however, is dramatically reduce virus transmission and infection. For that, we would benefit from intranasal vaccines.

The vast majority of antibodies elicited by intramuscular vaccines are the types (IgM or IgG) that circulate in blood and tissues. A small minority are the type (IgA) that are distributed at the mucosal surfaces of the nose, eyes and mouth, where we are most vulnerable to respiratory viruses such as SARS-CoV-2. This limitation has become even more apparent with the emergence of the omicron variant that has led to large outbreaks of infection in both fully vaccinated and boosted individuals.

In contrast, while intranasal vaccines also elicit antibodies and T cells that circulate throughout the body, they are most efficient at inducing the production of the antibodies that can bind to viruses before they invade mucosal surfaces such asthe lining of the nose, which has the highest concentration of ACE2, the receptor for the spike protein of SARS-CoV-2.

There are encouraging results inmonkeys and rodentsthat have received intranasal vaccines containing the portion of the SARS-CoV-2 virus that binds to the ACE2 receptor. Vaccinated animals develop IgA as well as IgM and IgG antibodies to SARS-CoV-2. When inoculated with infectious SARS-CoV-2, they not only are protected from disease but also have low or undetectable levels of virus in their nasal passages.

The holy grail ofherd immunity the percentage of the population that would need to be immune to the virus through infection or vaccination is areceding target. The already challenging estimate was thought early in the pandemic to be near 70 percent coverage. After the first variants, the estimate increased to near 80 percent. And with the more transmissible omicron variant, it is now estimated that, if it could be reached at all, it would require more than9 out of every 10 to be vaccinated.

The most important factor in the emergence of variants is unvaccinated people within whom SARS-CoV-2 reproduces and evolves to even greater fitness for growth in humans. Global vaccination is the only way for us to starve the virus of the opportunity for creating additional new variants.

The major impediments to global vaccination are hesitancy, production and delivery. A study in the United Kingdom of more than 15,000 adults reported aninjection phobiain approximately 10 percent of vaccine hesitant individuals and found that injection fears were highest in younger, Black and Asian individuals.

A shift to less invasive intranasal vaccines should result in improved compliance. Intranasal vaccines will still require regulated, rigorous manufacturing processes; nonetheless, they will not need highly trained vaccinators or the level of sterility required with injectable vaccines. Furthermore, none of the intranasal vaccines in development are as perishable as the RNA vaccines.In short, intranasal vaccines should be less expensive to manufacture, transport and administer.

What are the downsides? We have limited experience with intranasal vaccines, and our vaccine manufacturing facilities are designed to produce injectable vaccines. The only intranasal vaccines in common use are against influenza viruses, which have adapted to grow in the colder environment of the nose (34 degrees centigrade) rather than the lungs (37 degrees centigrade), where they can cause severe disease. There is a hypothetical increase in risk for facial muscle weakness, better known as Bell's palsy. Although not life-threatening,it could be disfiguring. However, the only intranasal vaccine found to cause this problem was an inactivated influenza vaccine that included an immune system stimulant.That vaccine was discontinued in Europe and was never used in the United States. Furthermore, risk would be mitigated by following the same rigorous safety and efficacy testing applied to the injectable Pfizer-BioNTech, Moderna and Johnson & Johnson vaccines.

We do not propose that the world abandon the injectable vaccines that have already saved millions of lives. Indeed, the ideal vaccine cocktail may include injectable and intranasal components. Nonetheless, as the pandemic enters year three without signs of abatement, it's time to think about new strategies for containing the contagion.
