I know that other medications also can have side effects. The vaccine was made in a very short time, compared to other vaccines in the past, and it was just physically impossible to test its long-term effects on a human body, because just not enough time has passed yet. Don't get me wrong, I'm not calling everyone for not using the vaccine, do whatever thing if you will, but this is just an explanation why there are people who are skeptical about the vaccination and refuse to use it.
I already don't believe EVERYTHING I see on the internet, do you? That's stupid, should be obvious to anyone.
