A study done by Cleveland Clinic using "robust data" from 51,977 subjects shows that the more shots you take to prevent COVID, the higher your chance of getting it.
Using the predominant BA.4/BA.5 strains in Ohio at the time, the researchers also found that the current bivalent vaccines were only about 30% effective. "Furthermore, the data reveals the greater number of mRNA doses, the greater the incidence of SARS-CoV-2 infection. Unfortunately, this isn't a great look," Trial Site News reporters said.
While they reminded readers the study still has to be peer-reviewed and therefore "not be cited as evidence," they added that the large sample size and the fact it was conducted in an actual health care setting helps rank it high in strength as a trusted source.
