Sept.14 (UPI) — Immunity from the Moderna COVID-19 vaccine lasts at least six months, and there is no indication that fully vaccinated people will need a booster shot, a small study published Tuesday by Science found. The vaccine also appears to produce long-lasting protection against the coronavirus in people of all ages, including those 70 and older who are at higher risk for serious illness, the data showed. « The immune memory was stable, and that was impressive, » co-author Shane Crotty said in a press release. « That’s a good indicator of the durability » of both the Moderna and Pfizer-BioNTech vaccines, which are made using similar formulations, said Crotty, a professor of vaccine research at the La Jolla Institute. The findings are based on an analysis of 35 people enrolled in early clinical trials of the vaccine, who received a low-dose version that is equivalent to one-quarter of the 100-microgram dose now given, the researchers said. « We wanted to see if a quarter of the dose is able to induce any immune response, » study co-author Jose Mateus Triviño said in a press release.
