A new study from the Cleveland Clinic shows that the more Covid vaccines one gets, the higher the risk of Covid. This is a statistical analysis, not a human trial, but an interesting one.
The study says, “The higher the number of vaccines previously received, the higher the risk of contracting COVID-19.” Further, the study found that “the current bivalent vaccines were about 30% effective overall in protecting against infection with SARS-CoV-2, when the Omicron BA.4/BA.5 lineages were the predominant circulating strains.”
This was a study of over 51,000 adults. The researchers concede that this is not the only study to indicate that risk of infection may actually go up with more vaccinations. They say that they could not infer anything about the vaccine preventing severe Covid because in a study of 51,000 people, “there were too few severe illnesses for the study to be able to determine if the vaccine decreased severity of illness.”
