Coved Pandemic Vaccine Booster Shots - The Fda Authorizes a Second Boost Shot

The fda authorized a second booster shot, on top of the ones given every year. The move makes boosters available to adults age 50 and older and anyone 12 elder who is imuno compromised. Some experts are not convinced that a second booster will significantly improve immunity. It may top up anti bodies for a few months, but at a certain point, with additional shots, we may see diminishing returns.
