The new head of the Center for Disease Control (CDC) said Sunday that the U.S. has to "go faster" than the Biden administration's current goal of 100 million coronavirus vaccinations in 100 days. Dr. Rochelle Walensky acknowledged that the administration faces certain constraints in its "race" against the virus. Biden's nominee for Surgeon General, Dr. Vivek Murthy, echoed the sentiment that the administration's vaccination goal is on the low side. So far, no other strains have appeared, but some believe that it is only a matter of time. "The more virus that is out there, the more virus that is replicating, the more likely that we are going to have mutations and variants."
