Quick takeaways

  • An observational study from Austria suggests that annual booster campaigns may not reduce the risk of COVID-19 death in individuals who have recovered from COVID-19.
  • The study found that while boosters had a small and temporary effect on preventing individuals from testing positive for COVID-19, they did not offer protection against severe disease or death for people who have already had COVID-19.
