Nearly all Pennsylvanians had COVID-19 antibodies through vaccination or a previous infection through last year, according to a new nationwide study.
The CDC recently released the results of its 2022 COVID-19 antibody study of more than 143,000 blood donors. The study reviewed data from October 2022 through December 2022. It measured the population’s COVID-19 seroprevalence, or the number of Americans with antibodies against the virus due to infection or vaccination.
Public health officials cautioned that more research is needed to understand the degree COVID-19 antibodies correlate with protection against the virus.
“Current protection (is) likely influenced by both cumulative number of vaccine doses, number of times infected, and timing of most recent vaccination or infection, and how closely the circulating variant matches the vaccine or prior infection,” CDC advisors noted during a meeting last month.
