Mix and match? New tests investigate switching vaccines for booster shots

NIH and NIAID test combinations of vaccinations and boosters

LINCOLN, Neb. (KLKN) – The National Institutes of Health, through the National Institute of Allergies and Infectious Diseases are testing out different combinations of vaccine to see if they might do a better job when it comes time to boost your COVID-19 immunity.

Bryan Health pulmonologist Kevin Reichmuth explains the thinking here. “Maybe it’s a different platform, either one of the existing ones, or something yet to be approved. That would provide even a better improvement or boost in the immune system, because you’re stimulating it in a slightly different way.”

For instance, if your full vaccination was Pfizer, you may get a booster shot from Moderna, or vice versa. Of course, this is all experimental just now, and the test is only about boosters. There isn’t any talk of switching up vaccines halfway through the vaccination process. Not here, at least. Some places, like Canada, have decided that’s safe to do.

“They’re kind of taking a leap a little faster with regards to the mixing and matching before all of the data is in”, says Reichmuth. “I think we’ll have to just see. They may not be the only country that’s going to take that leap of faith.”

That may be the case very soon, as the United Kingdom has tried that idea out for themselves. Their findings are expected to be released sometime this summer.
