Sorry but both the CDC and the FDA are under the thumb of Biden commissars. They are not credible in the opinion of many physicians and free thinking scientists.
I know ivermectin plus the vitamins works! It has worked extremely well for me and 8 of my friends. Another friend did not believe it and he ended up on a vent 30 days in fall 2020. He still is not quite recovered. He is lucky to be alive. BTW many of my other acquaintances are sicker than dogs right now. You guessed it. All of them have had at least one or more COVID vaccinations. It is quite disturbing. Some gave gotten the crud two or three times since their kast vax. Usually lasts about a week.
They did this BEFORE Biden
