The antibodies triggered by COVID-19 vaccines are interfering with people’s immune systems as newer virus variants emerge, Dr. Harvey Risch said.
The two most widely-used vaccines in the United States, produced by Pfizer and Moderna, both work by sending messenger RNA into muscle cells, where they produce a piece of the spike protein from the virus that causes COVID-19. The spike protein triggers the production of antibodies, which are believed to help prevent infection by SARS-CoV-2, which causes COVID-19, and fight illness if one still gets infected.
But the vaccines are based on the spike protein from the original virus variant, which was displaced early in the pandemic. Since then, a series of newer strains have become dominant around the world, with the latest being BA.5….
