ROCHESTER, N.Y. (WHEC)— A study is underway to uncover the benefits of something you've asked us about.- mixing different vaccines.
Oxford University researchers are doing a clinical trial that looks at four vaccines: Pfizer, Moderna, AstraZeneca, and Novavax. If successful, researchers say mixing and matching could be a way of working around supply shortages and speeding up vaccination programs.
"Vaccine supply may not be as regular, you may get a big delivery of one vaccine and then a few months later a big delivery of another vaccine," Professor Matthew Snape said. "You're not going to be able to control the supply in the first and second doses as well, perhaps as some other countries. so these mixed schedules might well be the key to getting two doses into as many people in the world as possible."
Right now, only Moderna and Pfizer are being used in the United States, as Johnson and Johnson is also approved but remains on hold.
AstraZeneca could get FDA emergency approval in the coming weeks.
