Sorry I cant follow. I was arguing for quite the opposite, just assuming something will help wont make it so. We know there is heart damage as well as long covid even in low and asymptomatic cases. Sure you can bet that the vaccines will help there as well, but how confident are you in that? Because as far as i know nobody promised anything of the sorts. It is a leaky vaccine, you still get sick, you just get lung antibodies so you dont end up on intensive care.

Are you really willing to risk both on the grounds that it might or might not help? I would say if you dont know, you assume that its not a magic shield and adapt your behavior accordingly. Which means so you dont catch it.
