Article Synopsis
- There’s confusion in the scientific community about what constitutes a COVID-19 vaccination impact study due to unclear definitions and terminology.
- This narrative review evaluates 18 studies from 48 countries (32 high-income and 16 low/middle-income) to analyze common characteristics, methodologies, and insights on vaccine impact.
- The review finds that while all studies focus on vaccination impact, they vary significantly in objectives, definitions, methodologies, and outcome variables, which reflects diverse data sources and analytical approaches.
Background: A vaccination campaign targeted adults in response to the pandemic in the City of Rio de Janeiro.
Objective: We aimed to evaluate the seroprevalence of SARS-CoV-2 antibodies and identify factors associated with seropositivity on vaccinated and unvaccinated residents.
Methods: We performed a seroepidemiologic survey in all residents of Paquetá Island, a neighborhood of Rio de Janeiro city, during the COVID-19 vaccine roll-out.
