Waning effectiveness of the third dose of the BNT162b2 mRNA COVID-19 vaccine
Abstract
In this retrospective study, authors show that relative protection against SARS-CoV-2 infection wanes from 53.4% one month after vaccination to 16.5% three months after vaccination, suggesting that there is a significant waning of mRNA vaccine effectiveness against infection with the Omicron variant.
