CDC warns COVID-19 may be a few mutations away from evading vaccines

COVID-19 may be “just a few mutations” away from being able to evade vaccines, CDC Director Dr. Rochelle Walensky warned Tuesday.

Walensky said the current vaccines are effective against severe cases of the coronavirus, including those caused by its known variants, but its continuing spread could allow the disease to mutate beyond the immunizations’ protection. “The largest concern that I think we in public health and sciences are worried about is that virus and potential mutations … [have] the potential to evade our vaccine in terms of how it protects us from severe disease and death,” Walensky said at a press briefing.
