The FDA could soon move to approve the mixing and matching of COVID-19 vaccines, especially good news for those seeking a different booster shot. Dr. Lisa Morici with the Tulane School of Medicine says, “What we’re hearing is that they may allow individuals to mix and match, meaning if you got the messenger RNA vaccine you might have an option to get the Johnson & Johnson should you desire to do that.”
Dr. Morici says that studies are showing that the mixing of vaccines shots has actually had a positive impact on producing higher antibody responses. She says the mixing of vaccine boosters has shown no indication of being harmful. “We’re not seeing any worsening of the side effects or any unexpected events from mixing and matching the vaccines,” according to Morici.
Morici says data from overseas indicates a positive response to the mix-and-match approach. “Studies out of Europe had shown us that the Astra-Zenica vaccine, which is an adenovirus-based vaccine when individuals were immunized with that vaccine and then boosted with one of the mRNA vaccines they mounted much higher antibody responses,” said Morici.
The FDA is also expected to give emergency use authorization to booster shots manufactured by Johnson & Johnson and Moderna.
