It's pretty hard to argue against vaccines when they've virtually eradicated a bunch of terrible diseases. Pretty much all those horror stories you hear about them from people is because they heard something on the internet that turned out being fake. The fact there's a measles outbreak in Western Canada this year after it was virtually non-existent for decades should be a pretty good indication of how ridiculous it is to ignore such an easy, painless medical practice because you're more afraid of something that's likely a crock of shit somebody fabricated over a serious illness that's entirely preventable. Isn't that a little strange and screwed up that people are more inclined to believe rumours over hard facts? 

Seriously. Vaccinate your damn kids. If they get brutally ill because you'd rather trust some sensationalist garbage over solid medical advice and practices that have been safely used for decades, you're a selfish idiot who should have never bred because you clearly aren't a responsible human being.
