You know what? **** it. I have an idea. How about everyone who chooses to not vaccinate (and I'm not talking about flu vaccines even) go all live together on an island for a year. See how much you guys like it when you don't have a layer of herd immunity to slow down preventable illnesses. Or failing that visit a country where people line up for days for even the chance to get a vaccine. Go on. Put your amazing immune system to the test. I dare you!
I'm not saying you're wrong because the evidence is clear that people are easily susceptible to the mentioned diseases. But my mother never immunised me and I lived in India on and off as a kid until I was 6. I never got sick from any disease while plenty of other kids I knew, including ones I was around at school when they got sick, were immunised (here I'm specifically referring to measles and whooping cough). The only thing I've ever had was chicken pox at the age of 7 and it really wasn't that bad. Growing up in a hippy area, I know quite a few families that didn't immunise their kids and being 'Hindus' most of us traveled to and lived in India without any health issues. On the other hand, I know a few people who've gone over there and to Indonesia having been immunised against malaria and they still got malaria.
But I do consider myself lucky more than anything, and grateful to have a mum that kept me healthy and strong even if she was anti-vax.
