COVID-19 cases are falling in the U.S. because 245 million doses of one of the available COVID-19 vaccines have been administered, according to Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group. "But at the same time, there are still people who need more information about the safety and the value of getting a COVID-19 vaccine," says Dr. Poland.

While still hopeful, Dr. Poland says he's concerned herd immunity won't be reached in the U.S. through vaccination. And that will mean more tragic deaths due to COVID-19 infection.

"My guess is, because we're such an interconnected global community until everybody's safe, none of us are safe. And we're going to likely see continued circulation of the virus, and that virus will seek out whoever is not immune," says Dr. Poland.

In this Mayo Clinic Q&A podcast, Dr. Poland also addresses when we will need COVID-19 vaccine boosters will be needed and the latest on masking guidelines from the Center for Disease Control and Prevention. Plus, he will provide an update on COVID-19 treatments and how to handle those who want to visit a newborn baby.
