I got Whooping Cough recently at age 43, what fun. Apparently vaccine immunity for WC wears off after a few decades. It was as ill as I have ever been and I was pretty much out of action for 3 months. There has been an increase of WC cases recently in the SW of England, where I live. I could rant at anti -vaccine campaigners, but what would be the point? I am more concerned that the people who are unsure have access to a clear statement of the pro-vaccine position.
So can I suggest that anyone who is unsure about vaccination reads "Deadly Choices" on the pro-vaccine front even if they read nothing else?
I just had my early summer ruined. But babies get killed by this kind of thing. I totally get why people find vaccines icky and unsettling, there are hard wired ways we intuitively think about our bodies that foster that kind of reaction. So just read this book if you're on the fence OK? It would be nice if lots of other 40-somethings don't irritate everyone else with their wheezing and self-pity
