French study shows COVID vaccine efficacy 94% against severe outcomes

In late December 2019, France began administering vaccinations against coronavirus disease 2019 (COVID-19) to its population. At the end of 2021, 77% of the entire population were fully vaccinated, and 91% of those 18 years or older. During these times, France experienced three epidemic waves caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants Alpha, Delta, and Omicron. Vaccination administration was stratified among the different population groups due to limited availability, begging with those at most risk of severe COVID-19-related complications and those who work in healthcare. Moderna, Pfizer/BioNTech, AstraZeneca, and Janssen were the four Covid-19 vaccine brands utilized. With the exception of the Janssen vaccine, which only required one dosage, a vaccination program was initially considered complete following two doses. A complete vaccination cycle had become a prerequisite for obtaining a French health permit, which became effective in June and was first necessary to enter events and places with large crowds. In August, the health pass was expanded to include admission to all museums, bars, restaurants, railways, and other public venues.
