To be fair, I'm pretty sure your vaccine schedule over there has less shots in it than ours. But I don't know how all these people get away with not vaccinating. As a poor person you know you have to do everything the government "recommends", or they take your kids away.

Anyways as to reasons why some people might not vaccinate, lots of people have seen their family members suffer severe reactions to vaccines. Sometimes they even die. In my family multiple people have had these reactions so there was a chance my daughter would too. My two year old is fully vaccinated, but I was so afraid she would have severe side effects (they are common in my family and some of us have had to skip some vaccines or go without entirely).

I got all my shots as a kid and nothing that terrible happened to me though so I took the chance, because I've seen people get CPS called on them for not following the schedule. In many states they can charge you with child neglect. My mom went through a huge to-do trying to get my sister on a delayed schedule after she had increasingly bad reactions every time she got shots. Eventually she had a severe reaction to one of the five vaccines she got at 15 months (there's no way to tell which one) and she may have sustained permanent brain damage from the swelling and seizures. She seems OK developmentally (she's 3) but she was definitely much smarter and more capable before. She was speaking in full sentences before the shot and it took about 8 months for her to get back to that point after. She's still deathly afraid of doctors and hospitals, and she has only been to the doctor twice since then. Now we've moved to a new state and we get to go on the adventure of finding a doctor who won't call the authorities on us for not wanting to turn my sister into a vegetable. This whole "shun the crazy anti-vaxxers!" thing is making it really hard for those people who have legitimate medical reasons not to vaccinate, because they're being shunned and mocked too.
