The antibodies triggered by COVID-19 vaccines are interfering with people’s immune systems as newer virus variants emerge, according to Dr. Harvey Risch.
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 SARS-CoV-2, the virus that causes COVID-19. The spike protein triggers the production of antibodies, which are believed to help prevent infection and fight illness if one still gets infected.
