Funky maybe one of the docs on here would be better placed to explain in detail but in layman’s from what I’ve read - the vax boosts the immune system which in turn reduces viral load, this in turn makes it less likely that those in a highly vaccinated group would be infected enough to contract the virus, or if they did they would be asymptomatic, therefore slowing transmission and thus creating herd immunity. Which is why it’s so important to stop signing into Facebook and get the fucking vaccine. If people would prioritise general health over clubbing then we’d all be clubbing quicker together.
