“Be patient and hop online now and don’t forget those neighbors friends and family that don’t have internet access, help them make their appointments so that everyone can get their boosters,” Dr. Nancy Mimm, Professor of Popular Health at Harrisburg University, said.

Dr. Mimm says it is important to remember it is safe if the booster vaccine is different than the first COVID-19 vaccine(s) the individual received.
