The Pfizer-BioNTech and Moderna COVID vaccines contain snippets of viral genetic material called mRNA. Once injected, it can’t create a whole virus, but it does tell cells to build one isolated piece, the infamous spike protein found on the surface of SARS-CoV-2. When the human immune system detects that protein, it starts to produce antibodies and...
The FDA authorization was based on clinical trials of earlier versions of bivalent boosters (made with components of previous SARS-CoV-2 variants), mouse studies of the current bivalent boosters and real-world experience with the COVID mRNA vaccines. Clinical trials of these newest formulations are still being conducted, so their data did not figur...
