Table 1.
Estimated vaccine effectiveness for all nationally available COVID-19 vaccines in Mexico compared to unvaccinated adults (≥18 years) from December 24, 2020, until September 27, 2021. Effectiveness was estimated against laboratory-confirmed SARS-CoV-2 infection, COVID-19-related hospitalization and death. Partial and fully vaccinated status were considered for individuals with ≥14 days from vaccination until outcome.
