Data shows people who only received one dose of the Moderna or the Pfizer vaccine have a higher likelihood of contracting the delta variant of the coronavirus.

Dr. Timothy Friel, chairman of the Department of Medicine and an infectious disease specialist at Lehigh Valley Health Network, said even those who didn’t get their second shot in the recommended window should still get it. 

“That second dose really is the powerhouse that activates the cellular side and that’s what preserves the memory that our immune system has, such that if we’re ever exposed in the future to coronavirus, or a similarly structured virus, that our immune system will have some memory and be able to react,” Friel said.

People who still need to get a second dose can go to a local pharmacy or to to make an appointment.
