For someone not well versed in virology, can you please explain what that means?
How do you get infected with significant levels of cellular immunity? And does that mean the infection is less severe?
- nradov 5y agoThere are multiple components to the immune system. For some viruses like measles, prior infection or vaccination usually triggers production of sterilizing antibodies which block subsequent infections in most patients. That isn't really the case for COVID-19. However the immune system also contains memory cells which can ramp up defenses more quickly during reinfections. The targets for those defenses are mostly the same across all SARS-CoV-2 variants. I have oversimplified this explanation to keep the comment short. If you'd like to really understand what's going on I recommend this panel discussion by a group of leading physicians; it's long but worth a listen. https://youtu.be/GklHGYY8vN8 https://youtu.be/GklHGYY8vN8
