As an emergency physician, Dr. Eugenia South was in the first group of people to receive a COVID-19 vaccine. She received her second dose last week — even before President Joe Biden.
Yet South said she’s in no rush to throw away her face mask.
“I honestly don’t think I’ll ever go without a mask at work again,” said South, faculty director of the Urban Health Lab at the University of Pennsylvania in Philadelphia. “I don’t think I’ll ever feel safe doing that.”
And although COVID-19 vaccines are highly effective, South plans to continue wearing her mask outside the hospital as well.
Health experts say there are good reasons to follow her example.
“Masks and social distancing will need to continue into the foreseeable future — until we have some level of herd immunity,” said Dr. Preeti Malani, chief health officer at the University of Michigan. “Masks and distancing are here to stay.”
Malani and other health experts explained five reasons Americans should hold on to their masks:
1. No vaccine is 100% effective.
Large clinical trials found that two doses of the Moderna and Pfizer-BioNTech vaccines prevented 95% of illnesses caused by the coronavirus. While those results are impressive, 1 in 20 people are left unprotected, said Dr. Tom Frieden, a former director of the Centers for Disease Control and Prevention.
Malani notes that vaccines were tested in controlled clinical trials at top medical centers, under optimal conditions.
