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.
