This report in The Freethinker details the importance of a robust vaccination programme for the health and wellbeing of citizens across the globe. This is science (bitches – ooh, Dawkins, so rude) and this is how it helps progress.
Or, this is backward church anti-vax thinking, and this is how it hinders progress.
It is no surprise that something like this has happened. In fact, I believe we had a measles outbreak earlier this year in the UK (esp. Wales) due to a lack of vaccination in certain demographics.
