COVID-19 variants and the evolving science
Feb. 24, 2021
People may be curious, confused or critical of what seem to be changing messages related to the COVID-19 pandemic.
"As we learn new science, we use that science to modify our recommendations," says Dr. Poland. "It's not that scientists are flip-flopping. It is that new data allows us to begin expanding those recommendations."
For instance, COVID-19 cases and deaths in the U.S. are currently declining. But, Dr. Poland says, there are new data predicting the possibility of another surge of COVID-19 infections in March because of U.K. variant transmission.
In this Mayo Clinic Q&A podcast Dr. Poland talks about several issues, including the U.K. variant, vaccine development and the public’s COVID-19 fatigue.
