There is no indication that vaccination changes that. You still get it and and if i had to guess, lung antibodies will likely help as much for heart problems as they do for upper respiratory symptoms.

Your guesses are worthless (as are mine), unless you have some expertise. The last thing we need is more BS on the Internet about Coronavirus.
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.
