I have done a little bit of research on the SF vaccine and its effect on kids- we got that letter asking if we wanted to include DS in the study of the vaccine on kids, and so before I consented to it, I did some research.

Bearing in mind that I am pro-vaccine in general, the news was predominantly positive. There were very, very few reports of any negative side effects of the vaccine in kids (or adults for that matter), and my general impression is that it is no more or no less dangerous than any vaccine- ie- it carries some risk, but that risk needs to be weighed against the risk of the illness. Because SF seems particularly nasty to youngsters, I will definately be getting DS vaccinated (as well as ourselves). In my research, the articles I read about how many otherwise healthy children in the States have died from SF freaked me right out.

We haven't had it done yet, so I can't speak from personal experience, but for whatever my research is worth, we're going ahead!
