The vaccines don’t train the immune system correctly. Usually when you are infected you get a fever and the immune system has to go trough a certain process. With vaccines you get the antibodies for the virus, but this makes the immune system react in a unnatural way.

You wind up with the same thing: Antibodies. And way safer than getting the actual disease. It isn't "unnatural", it just isn't from getting the disease.

I'm gonna trust the health professionals here.
