Centers for Disease Control and Prevention (CDC) Director Dr. Rochelle Walensky told reporters during a July 27 teleconference that her biggest concern is that the CCP virus may be “just a few mutations” away from being able to evade vaccines.
“The largest concern that I think we in public health and science are worried about is that virus and the potential mutations. We have a very transmissible virus, which has the potential to evade our vaccines in terms of how it protects us from severe disease and death,” Walensky said.
