New COVID boosters that will be available by week's end are receiving some scrutiny due to clinical trials being performed on mice and not humans.
The boosters made by Pfizer-BioNTech and Moderna were approved by the Food and Drug Administration (FDA) on Monday. On Tuesday, a panel of advisers to the Centers for Disease Control and Prevention (CDC) voted 13-1 in favor of its broad use for individuals 6 months and older due to fears of increased respiratory illnesses nationwide this fall and winter.
The new vaccines will be available at national pharmacies including CVS and Walgreens, and at local pharmacies, doctors' offices and public health departments based on location.
These updated boosters will be the first released to the public without any humans involved in the clinical trials, raising questions from some about the efficacy.
