Vaccine uptake pre- and post-COVID-19 in American adults: a retrospective observational study using the Behavioral Risk Factor Surveillance System

Despite free access to the COVID-19 vaccine, healthcare coverage significantly influenced its uptake. Increases in RZV and FLU vaccination among the insured, in contrast to minimal changes or decreases among the uninsured, highlight the critical role of healthcare access. While RZV and FLU uptake improved post-pandemic, PnV uptake remained stable. We found no evidence that COVID-19 vaccine safety affected RZV, FLU, and PnV vaccination rates.
