COVID-19 Booster Dose Evidence: Reduced Mortality Within 6 Months - 0 views

pharmacybiz on 15 Dec 23A new study has revealed that the risk of death from COVID-19 decreases significantly after vaccination, but this protection diminishes after six months, providing evidence for continued booster doses. Researchers from the UK Health Security Agency (UKHSA), who analysed more than 10 million cases of COVID-19 in adults in England between May 2020 and February 2022, found a clear association between vaccination and reduced mortality. But they also highlighted a crucial timeframe - within six months of the last vaccine dose - when Case Fatality Risk (CFR) - the proportion of cases that resulted in death - was consistently at its lowest across all age groups. After this, the protective benefit of the vaccine began to wane and CFR increased.
