Anti-vaccine people are everywhere.
People probably don't understand what ugly diseases were eradicated by vaccines in the amount of time since the first vaccine was created. This is not because they don't know it theoretically, but they know nothing about those diseases.
Here any new born child receives since birth few very important vaccines and I think that this is a good thinng. Imagine some people are nowadays against these as well, after decades of practising them...
Side note, the second shot of the Pfizer vaccine made me unable to stay on my feet and i was for a whole day powerless and dizzy.
It was such a strong reaction i never imagined before, but when i finally caught the virus my body was ready to fight it and that day of feeling bad was totally worthy.
I think people refusing the vaccine are like the scientists who proved years ago that from a train going faster than 30 km per hour the air comes out of it and the humans inside die. Luckily there were some insane pople practically proving wrong the scientists of the time and we have now high speed trains.
