As continuing research guides medical recommendations, it seems that there are COVID-19 updates released daily. These recommendations cover a range of topics, including whether COVID-19 booster vaccinations are necessary to whether COVID-19 vaccines can be mixed and matched.

"The fact that recommendations are changing is not evidence people don't know what they're doing," says Dr. Gregory Poland, head of Mayo Clinic's Vaccine Research Group. "It's evidence that they do know what they're doing and are paying close attention to new data that's coming along. Then they're adjusting recommendations based on the latest data."

Dr. Poland continues to urge people to get the latest COVID-19 news from credible sources.

In this Mayo Clinic Q&A podcast, Dr. Poland walks through the recent recommendations, corrects misperceptions and answers a number of listener questions.

Watch: Dr. Greg Poland discusses the latest COVID-19 recommendations and answers listener questions.
