KNOXVILLE, Tenn. (WVLT) - Tennessee is steadily working towards full vaccination status. Over four million vaccines have been administered statewide and over 35 percent of Tennesseans have received at least one dose, according to the State Health Department.

Should COVID-19 booster shots be needed in the coming months or years, will you have to get the same type as your original vaccine? That could be the case, WHSV reports.

WHSV spoke to University of Virginia Infectious Disease Doctor Bill Petri about the matter and he said it could all come down to testing and studies.

“The short answer is probably yes, because the studies are going to be done boosting Pfizer with Pfizer or boosting Moderna with Moderna or J&J with J&J so the companies are going to do the studies and they are just going to boost their own vaccine,” Dr. Petri said to WHSV.

Dr. Petri added that the reasoning behind getting the same type of vaccine is due to how vaccine studies are completed.

“The phase three clinical trials, if they stayed true, if you got dose one Pfizer dose two is Pfizer but there is no immunologic reason that has to be. I think we would be fine a year from now getting boosted with either of the three vaccines,” Dr. Petri said.
