Predictably enough, the anti-vaccination lobby has been turning its attention to H1N1 vaccinations of late in articles such as this one and the rather more hysterical “ZOMG!  Genocide!” blather I mentioned before.  With that in mind, I’d thoroughly recommend this article on the Lay Scientist blog: a mature, non-hysterical examination of the strongest plausible worry that ought (in a reasonably well-put-together world) head off the critics at the pass.  There is a risk from vaccinations – that’s because we’re injecting people with biologically active stuff, duh – but there’s a risk in not being vaccinated, too.
