Reinfection and post-vaccination infection by SARS-CoV-2 in nursing professionals: a prospective cohort study, Recife, 2020-2023

This finding of a reduced occurrence of infections among individuals vaccinated with at least one dose and with a history of prior SARS-CoV-2 infection reinforces the evidence base for hybrid immunity. However, despite the number of infections and reinfections among these professionals, further research is needed to systematize information on primary and recurrent infection cases in this population group, in order to enhance understanding of the phenomenon and improve surveillance processes, as well as prevention, control, and care measures targeting this professional category.
