Science, the study collected data of 780,225 veterans from the Veterans Health Administration between Feb. 1 and Oct. 1.Nearly 500,000 of them had been inoculated while just shy of 300,000 had not.Researchers found each of the vaccines initially offered high levels of protection against infection.
In March, Moderna’s protection measured at 89%, Pfizers registered at 87% and J&J came in at 86%.But six months later, Moderna’s jab had dropped to just 58% effective, Pfizer was 45% and J&J fell to a mere 13%.Experts have long stressed the vaccines wouldn’t prevent all cases, which was demonstrated again by this study.
