Abstract

Live-attenuated virus vaccines, such as yellow fever vaccine, exhibit non-specific immunomodulatory effects, prompting exploration of their potential impact on COVID-19 pandemic. In this retrospective study, we didn’t observe an association between prior yellow fever vaccination with SARS-CoV-2 infection incidence. In the multivariate model, no association was found with COVID-19 prognosis.
