The director of the U.S. Centers for Disease Control and Prevention, Rochelle Walensky, MD, MPH, said last week during a media briefing that the large numbers of people walking around unvaccinated against COVID-19 not only make it more likely that hospitalizations and deaths will continue to rise but also more likely a variant will arise that even vaccinations are unable to stop.
The bad case scenario described by Dr. Walensky could be “just a few mutations away” from where the world finds itself now with the Delta variant.
