Based on past experience with seasonal colds and flu, public health experts are warning of a possible surge of COVID-19 cases this winter.

That’s, in part, because cold weather forces people indoors where airborne transmission thrives, and the now-dominant BA.5 Omicron variant is known to be highly contagious. So this month the United States endorsed new combination booster shots of both the Moderna and Pfizer-BioNTech vaccine formulations. They’re expected to provide increased and longer-lasting protection against the original COVID strain — and critically — against the newer variants.

To discuss:

  • Peter Chin-Hong is a professor of medicine and an infectious disease specialist at the University of California, San Francisco.
  • Kate Tulenko is the founder and CEO of Corvus Health.
  • Melanie Yazzie is an assistant professor of American Indian Studies at the University of Minnesota. 
  • William Haseltine is chair and president of Access Health International, and author of the new book — “A Family Guide to Long Covid: Questions & Answers”.
