I find the anti vaccine rhetoric on the web incredibly depressing and worrying. :(
By not vaccinating your kids, you don't just put them at risk, you decrease the 'herd immunity' which protects the population at large. There were measles outbreaks in South Wales a little while back (including deaths) precisely because the level of immunisation is falling. Why, oh why, are people trusting random bloggers on the web over the extensive research done by epidemiologist? It's like a weird mix of extreme paranoia and extreme gullibility.
Let's take MMR. There's new research showing that if you get measles it effectively wipes out two years of immune memory - in a toddler, that means they are pretty much immunologically naive again and that can be lethal.
If you track deaths from ALL infectious disease causes, they track pretty much along with the rise and fall of measles prevelance - yet the anti vaxxidiots are bleating on about measles being mild these days and no cause for concern. They are wrong. Very, very wrong - and it is killing people.
The web is a great tool for knowledge, but there's an awful lot of misinformation out there, and much of it is downright dangerous.
Whooping cough is out there in the community - it is at best a really horrible thing to catch and at worst lethal. Please, please vaccinate your kids and yourself
