It's not just antibodies though. Vaccines also trigger you to get memory cells, which have a longer life span. So even if your antibody levels go down after ~6 months, and you might get infected again, your immune system will have a faster and more precise reaction, preventing a more severe course of covid.
- fy20 5y agoThis is what a lot of people do not understand. Antibodies are basically the front line soldiers fighting the virus, but there's no point keeping them deployed even after the war is over. Memory cells circulate in the blood stream for much longer - sometimes decades for other pathogens - and if they identify their target antigen, will quickly trigger an immune response and produce new antibodies. Having a high number of antibodies correlates with a strong immune response and lower rates of incidence, but that doesn't mean having a high number of antibodies is needed for that. It's really too early to say exactly how long term immune response works with this virus, as the only studies that have been completed so far are small samples sets or short time frames.
