UNIVERSITY CITY - As states across the region expand COVID vaccine eligibility, questions regarding the vaccine remain.
One of the biggest questions on people’s minds is just how long do the vaccines last."Six months is kind of like the floor here.
That is the minimum," Doctor John Wherry, Director of the Institute of Immunology at University of Pennsylvania Perelman School of Medicine, said. "Six months is about the longest data we have from a reasonable sized number of people we can draw conclusions."What happens after that?
Are people still protected?"Extrapolating from what we know at six months, it’s like we are going to have immunity for easily a year, maybe two or three or longer.
