>Even if I drop dead, I couldn't give less of a shit
Then the vaccines shouldn't scare you, because they are safer than the virus.
>otherwise I believe a healthy immune system should be able to ward off this disease and provide a longer lasting immunity.
You're wrong.
>Has Germany started booster campaigns yet?
Yes. But only for a very limited amount of people. Very old and at risk. The majority of people will not need to take them.
Listen, I don't want to argue with you about vaccines because I'm such a big fan of them or because I enjoy this argument. I think you're a guy who has a very rough time undeservedly so. But I also think you're making your life more difficult than it needs to be. This is such an example.
Just very pragmatically speaking, vaxxed status will make your life easier and less of a hassle with tests and such. Being unvaxxed will not provide you any benefits whatsoever.
In terms of health it is also not a smart decision to wait. Even if you're 99% going to be fine with covid, you're going to be 99,9% fine with the vaccines already available to you. There is no reason to postpone this.
