Front-line health care workers across the country are receiving the first COVID-19 vaccinations. With the recent approval of a second COVID-19 vaccine for use here in the U.S., more COVID-19 vaccine doses are expected to be available this week.

A Centers for Disease Control and Prevention panel has recommended allocating COVID-19 vaccines for the next phase. Phase 1b includes those who are 75 and older as well as front-line essential workers, including police, firefighters, teachers and grocery store workers. These vaccinations would begin when phase 1a, health care workers and long term care residents, is completed.

On the Mayo Clinic Q&A podcast, Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group, gives an update on vaccine approvals and the rollout phases.
