Yeah but the WHO just saidthislast year that herd immunity cannot be achieved by getting sick and building an immunity to the virus.
T-cell immunity is a thing, especially when it comes to a Coronavirus. Of course you can be re-infected with the coof, in fact you will be re-infected. Likely millions of people caught it in the first wave and have caught it again since. But as they've already been exposed the second, third and fourth infections will be either a mild cold to showing no symptoms.
The best explanation as to why a third to a half of the people who catch the coof are asymptomatic is likely because of underlying T-cell immunity. This is maybe due to having been exposed to other Coronaviruses or because Covid has been floating around for a lot longer than we think it has.
On the one hand the WHO is arguing for mass vaccination to build herd immunity not because of the short term antibody production, which will last a few weeks/months, but because it will trigger T-cell immunity. On the other they're arguing that catching the virus itself doesn't do that? Fuck off with this nonsense.
At this point in time we have no idea if mRNA vaccines give long term immunity. The best case scenario is that the vaccines won't prevent infections but will reduce the severity of symptoms when you do catch the bug. Immunologists know this but it seems to be too hard for politicians and journalists to wrap their heads around the concept.
BTW the worse case scenario is that the vaccines don't trigger a good T-cell response and they'll prove to be essentially useless.
