Sorry to go back, but here's an Australian medical professional's view on vaccinations. Measles is becoming much more prevalent than it should, especially in an age where we have the capacity to stop it.

From the article - "In the Philippines, the number of people who believe that vaccination can protect them has fallen precipitously from 82 per cent in 2015 to 22 per cent in 2018. The result has been a tremendous surge in measles cases with almost 13,000 cases and 200 deaths recorded at the beginning of 2019. Roughly more than 2 million children remain unvaccinated largely because of an unwillingness of parents to embrace vaccination."
That's a huge fall in belief in vaccination. I'd be interested to know why.
Personally I think it's irresponsible not to vaccinate for common diseases, unless your doctor thinks there is a specific reason why your child shouldn't be vaccinated.
I would be really uneasy about sending my kids to a school with a high proportion of unvaccinated kids.
Also, there are now whole industries springing up around anti-vaxxing. To consciously go and try to make money out of spreading, at best, dodgy science to scare people into not vaccinating kids is ridiculous, and is a real public health concern.
