Not sure if you follow the weekly webcasts from FLCCC, but on their August 18th, 2021 webcast, Dr. Keith Berkowitz points out that he's seeing vaccinated patients with high antibody counts (>2500) that are coming in with new COVID infections. I think he brings up a good question, namely does the immune response to the mRNA vaccines and the antibody measurements resulting from that provide any meaningful information with regard to efficacy.
