The team is set to study the duration of protective immunity among 800-1,200 nursing home residents following vaccination or when administered a booster shot, when federally recommended to do so, given emerging COVID-19 variants, 보도 자료에 따르면. Researchers plan to share interim data with the CDC as it becomes available.
“Given rising case counts of the Delta variant, we need to know as soon as possible who needs a vaccine booster shot and when they need it,” Stefan Gravenstein, co-lead investigator on the project and a professor of geriatric medicine at Brown University, 에 말했다 성명서. “This information on how specific immunity to SARS-CoV-2 infection declines with aging, disease and in long-term care residents is critically important for developing a booster strategy based on real-time data in this population.”
Gravenstein and a team of researchers’ recent preliminary findings noted a rise in breakthrough infections and outbreaks among nursing homes while reporting an over 85% decline in neutralizing antibody levels six months following vaccination with the Pfizer jab, regardless of prior infection, among nursing home residents and healthcare workers.
“Based on the rapid spread of the delta variant and reports of vaccine breakthrough in NH [nursing homes] and among younger community populations, boosting NH residents may be warranted,” a pre-print posted Aug. 20 읽다.
사무용 겉옷, Gravenstein said results thus far back the CDC’s recent recommendation for booster shots, planned to rollout in the coming weeks, pending FDA review. 하나, 건강 공무원 have advised the 백악관 that regulators need more time to review necessary 데이터 before approving a 코로나 바이러스 감염증 -19 : 코로나 19 booster shot plan.
The guidance from the Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (질병 통제 예방 센터) is that both agencies have so far only accumulated enough data to suggest that some individuals who received the Pfizer vaccine should get a booster shot.
