check out penn and teller's take on vaccinations in this
video via bad astronomy. heh. there's currently a pretty strong backlash against the well meaning but dangerously misinformed anti-vaccination movement. friends of ours tell of people who take their kids across the country to go to chicken pox parties specifically to infect their kids and get lifelong immunity the "natural" way. true story. this makes me think the most serious backlash is yet to come. namely when these kids become rebellious teenagers and realize their parents intentionally gave them horrible diseases when their peers got vaccinated. and didn't catch mumps, measles, chicken pox, polio, etc. nor autism neither.
