In 2014, Dr. Anthony Fauci was asked if someone who recently contracted the flu needed to get a flu vaccine, and he replied, "She doesn't need it because the most potent vaccination is getting infected yourself." Fauci, the CDC, and the World Health Organization have repeatedly cast doubt on the strength of naturally acquired immunity to Covid-19, but at least 20 studies have revealed evidence that it is potent and durable, even to the variants. Genetic facts showing this were published in a molecular biology journal during the very first week of the C-19 pandemic. Those facts also show that naturally acquired immunity to C-19 is much longer lasting than immunity to the flu. However, the vast bulk of media outlets have not reported these facts, and U.S. government agencies have virtually ignored them except on a website that stores copies of academic papers.
