Employees of Cleveland Clinic in employment on the day the bivalent COVID-19 vaccine first became available to employees, were included. The cumulative incidence of COVID-19 was examined over the following weeks. Protection provided by vaccination (analyzed as a time-dependent covariate) was evaluated using Cox proportional hazards regression. The analysis was adjusted for the pandemic phase when the last prior COVID-19 episode occurred, and the number of prior vaccine doses received.
Conclusion
Might as well get a placebo. The 4th booster is garbage, and worse than placebo. Boosted are at higher risk of infection and transmission

“Association of increase risk of COVID-19 with higher numbers of prior vaccine doses in our study of 51,011 employees was unexpected”
Wrong conclusion, a placebo would had been more safe.
