Right that’s weird, because I haven’t caught covid since November 2020 and am not vaccinated, however I know of about 20 fully vaccinated people that have caught it and probably passed it on in the last couple of months. I’ve probably done more socialising than them too, been to work, pubs, bars, gigs, football matches, the lot. Could it possibly be that natural immunity also makes you less likely to catch it do you think?
and @Wizard
so a vid I posted in here the other day spoke about the differences in immunity
IIRC, the natural infection produces something called IA antibodies (maybe IG). These antibodies are stored in the mucus in your throat/trachea, and attack the virus when it enters those areas. It also produces antibodies that are stored in the lungs.
The vaccine produces two other types of antibodies but not the ones that live in the mucus. They are the ones that live in the lungs. So that's why even with the vaccines you can still get infected, as it can get into your system more easily, but are unlikely to get badly ill.
You can still get re-infected with natural immunity, but it makes it less likely.
If you have both natural immunity and the vaccine, you've basically got double the amount of protection as all these antibodies are there.
The antibodies are of course different to the T cells, which will be created by both vaccination and natural immunity and stay in your system for a long long time and make it very unlikely you'd get seriously ill unless you are in some way compromised.
