While the idea of “viral mutation” may sound concerning, it’s important to understand that many of these mutations are minor, and don’t have an overall impact on how fast a virus spreads or potentially how severe a viral infection might be. WebHIV is a particularly notorious foe for both the natural immune system and for immune reactions spurred by vaccines in part because Env mutates so rapidly, slipping away from immune recognition before the body can effectively rid itself of the infection. city foods menu
