Vaccinations

Laura • 2 beautiful boys. East Yorkshire England 💚
I'm confused! Seein all these posts on here About women being ANTI-VACCINATIONS I understand everyone is different, but seriously?!? 
1) if they wasn't effective they wouldn't be given 
2) if they was dangerous they wouldn't be given
3) it's something that's been done for years and benefits the child 
4) don't change how they've always vaccinated a child
What's your views ? 
My first got vaccinated, done when they was ment to get done I didn't change a thing. My second that's de anytime I will also be doing the same. I'd never ever risk my child's health avoiding vaccinations. In my OPINION I think it's selfish and stupid if you don't vaccinate your child. 
FOR EVERYONE GETTING OFFENDED : this post isn't ment to be judgemental, THATS WHY I ASKED FOR VIEWS ON WHY YOU WOULDNT VACCINATE :S! If it was judgemental I wouldn't ask for others views
