Examining the bias in observational studies and the findings of a new Austrian study on the effectiveness of boosters in individuals who have recovered from COVID-19. Discussion on the Effectiveness of Booster Vaccinations and COVID-19 Death Rates: critique of a study from Austria that examines the impact of booster vaccinations on testing positive for COVID-19 and argues against boosters for temporary reduction in cases. Lack of Effectiveness of Booster Shots in Individuals with Previous COVID-19 Infection: study showing no reduction in COVID-19 deaths from booster shots in individuals with prior COVID-19 infection, highlighting durable natural immunity and critiquing US policy and FDA approval of boosters.
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.

Boosters don't work in people who have already had COVID-19
A new observational study from Austria focused on individuals who had recovered from COVID-19 and found that boosters did not reduce the risk of COVID-19 death in this group. This study challenges the efficacy of annual booster campaigns and suggests that they may not provide any significant benefit without better data.
Transient effect on testing positive but no impact on COVID-19 deaths
The same study also indicated a small and temporary effect of boosters on preventing individuals from testing positive for COVID-19. However, the authors emphasized that testing positive does not necessarily equate to being sick. Importantly, the study found no reduction in COVID-19 death rates among those who received the booster, indicating that boosters may not offer protection against severe disease or death for people who have already had COVID-19.
