Can the current crop of vaccines get us to herd immunity even if variants become widespread? A Harvard immunologist says yes.

A Harvard epidemiologist said the forces of seasonality, slowly rising immunity, and shifting personal behavior will likely create a viral variant landscape with regional spikes in the months to come rather than a uniform national wave.

With new coronavirus variants on the U.S. pandemic scene, experts say brace yourself for another surge — and mask up.

Harvard Medical School Professor Dan Barouch said the “complicated pandemic” means more work lies ahead.

Despite worries that a new coronavirus variant may be able to evade vaccines just being distributed, a Harvard public health expert expressed confidence in the same technology that produced the vaccines in record time.
