New COVID-19 vaccine study challenges stereotypes of who is getting the shots – The Boston Globe
April 14, 2022
Overall, the researchers found that stark disparities in vaccine and booster coverage persist in the state, leaving thousands vulnerable to severe illness as increasingly more transmissible forms of the virus circulate.
Despite a lull in COVID-19 infection rates, MA is in a precarious position, they wrote.
In the study, which was posted online Monday but not yet published in a peer-reviewed journal, the team analyzed state data on residents vaccinated and boosted by ZIP code through March 1. They also examined census-tract population estimates and ZIP-code-level socioeconomic and demographic data, including education level, household income, and profession.
When the researchers took education and age into account, they found that many communities with large concentrations of Black and Latino residents and essential workers had higher levels of vaccination than similar communities with many white residents and fewer essential workers.
For example, consider the towns of Randolph and Dartmouth. Both are south of Boston and have residents with similar age distributions and college graduation rates of roughly 27 percent. In Randolph, where Black and Latino residents make up about 53 percent of the population, 81 percent of the town had been vaccinated. Yet in Dartmouth, where 8 percent of residents are Black or Latino, just 60 percent of the community had been vaccinated.
This is not to say that race doesnt matter, said Jacob Bor, an assistant professor in epidemiology and global health at Boston Universitys School of Public Health and lead author of the study.
Race, ethnicity, age, and education levels overlap, he said. The team found that communities of color and those with a lot of essential workers are, on average, younger and have lower levels of education and lower incomes, which can affect peoples access to the shots.
These differences in income and education among Black, Latino, and Indigenous populations are a product of longstanding patterns of differential access to education, wealth, and opportunity, Bor said.
Income, the team found, was also a strong predictor of vaccination coverage. A $10,000 increase in a ZIP codes median household income was associated with higher vaccination and booster rates. From the lowest to the highest income levels, booster coverage increased from under 30 percent to over 60 percent.
Our analysis shows that education and income are better explanations for the patterns than race or ethnicity itself, said Dr. Jonathan Levy, who chairs the department of environmental health at BUs School of Public Health, and is senior author of the research.
But despite high, relatively equitable coverage for the original vaccine schedule in adults, researchers found large inequities in rates among children, and very large inequities for booster shots in all age groups.
In ZIP codes with the highest share of college-educated residents, about 70 percent of children have been vaccinated. Conversely, less than 40 percent of children have been vaccinated in the 10 percent of ZIP codes with the lowest percent of college educated residents, including those with the highest percentages of Black, Latino, and Indigenous populations.
We must redouble our ongoing efforts to overcome barriers related to poverty and education like collaborating with community partners who offer vaccination outside of health care venues, after hours, and on weekends, and provide clear and accurate information from trusted sources, said Dr. Bisola Ojikutu, Bostons Commissioner of Public Health, and a coauthor of the study.
The only way to address this inequity, she said, is through persistence.
Disparities were also pronounced when looking at who has received at least one booster shot, and controlling for education and age levels did not change that picture as it did for the primary vaccine series. The share of residents 65 and older who have received a booster was just over 50 percent in ZIP codes with the lowest share of college graduates and highest share of Black, Latino, or Indigenous people, the researchers found. Yet booster coverage was over 70 percent in more-educated ZIP codes and those with larger White populations.
A better understanding of the causes of the disparities should help policy makers address them, experts said.
This report highlights that people with complicated lives, and a lot of folks stereotyped as being hesitant, actually had high vaccination rates. And it really points to this being an access issue and we have to be better, said Atyia Martin, executive director for Next Leadership Development, a nonprofit that focuses on building resilience in Black communities.
While vaccines have been widely offered in local pharmacies and doctors offices, Martin and others said many lower-income essential workers often lack the transportation or time off, particularly if they suffer side effects after getting vaccinated.
We have to have strategies that are more sophisticated and account for peoples real lives and what theyre dealing with, Martin said. And we have to let the data be the guide for the decisions we are making.
The researchers suggested that strategies used successfully during the initial vaccine rollout, such as establishing more convenient places and times for essential workers to get the shots, should be widely extended for boosters. They also said Massachusetts should especially target this push in lower-educated communities, regardless of racial composition.
Brennan Klein, a post-doctoral researcher at Northeastern University who has studied COVID and racial biases, said the researchers careful statistical approach . . . offers [state policy leaders] a nice road map for how to direct vaccination efforts moving forward.
Nadia Abuelezam, an associate professor who specializes in biostatistics and health inequities at the Connell School of Nursing at Boston College, said the study offers very specific geographic information down to the ZIP code level for fine tuning public messages in future vaccination initiatives.
It allows us to think about where people live, work, and play, and how that influences their health, she said.
Michael Curry, chief executive of the League of Community Health Centers, was struck by the strong correlation the researchers found between education level and vaccination status. And he said that policy leaders, as well as health providers need to use that finding to guide ongoing and future vaccination efforts.
We have got to stop relying on people having a college degree or high school diploma to get what they need to make decisions on their health, he said.
We need employers to be in lockstep with providers and health plans, in constantly providing health information and wellness counseling that can prevent the high rates of morbidity and mortality in this pandemic, he said.
And, Curry added, that approach would be effective for other health initiatives, such as cancer screenings or diabetes care.
But the researchers expressed concern that the lessons from the pandemic, and the disparities revealed by their work, are not being heeded even now.
Rates of new vaccinations and boosters have slowed as Massachusetts has exited the winter surge and as officials now project a return to normal, said Bor, the studys lead author. Without new efforts to expand coverage, these inequities are likely to persist.
The upshot, he said, is that there are going to be a lot of people in poorer, lower-education ZIP codes regardless of racial composition who are going to suffer in future COVID waves because of low vaccination and booster rates.
