negative efficacy

Landmark study at the Cleveland Clinic that reluctantly admits the following: " [t]he risk of COVID-19 also increased with time since the most recent prior COVID-19 episode and with the number of vaccine doses previously received." In a study that like many others claims efficacy in the first months after vaccination dose, it ends up showing a far more alarming and important trend -- more shots lead to more positive test results over time-- for future issues with the vaccination program.
