OK, I'm going to get flamed for this by a bunch of knee-jerk vaccination good people, but WTF.
First strawman argument: which did not find convincing support for the idea that MMR shots caused autism . OK, so a load of people latch onto autism as a reason against vaccination, but its not the only concern. A lot of people are more concerned about lower-level negative immune system responses, such as increased allergy rates. Note that allergy rates have risen roughly in line with increasing hygiene and health-care in general (eg., hay fever was virtually unknown before the mid-1800s). Hygiene and health-care - vaccines included - affect the immune system, and its quite plausible that there is a balance point (between killing all but the healthiest or luckiest and weakened immune or damaged systems) which may have been passed.
I'm old enough to remember measle parties, clearly people in the 50s and 60s (in the West anyway) were not very worried about it. It was something your kids got, and the sooner the better. Why is measles becoming more serious? Natural immunity to measles (ie., getting the real thing) likely results in greater protection passed to the kids from the mother (can't give exact details but the wife is a biologist who's been involved in immune research in the past).
Then there's the multiple vaccination issue. The ability to survive an infection is a neccessary survival trait and would be selected for. The ability to survive multiple simultaneous infections much less so. Anyone see an issue here?
I'm not anti-vaccination per-se. I am against the knee-jerk vaccinate against everything policy that governments and pharma push. MMR. How many people get bad affects from Rubella - none, only the foetus, so test girls before puberty and vaccinate those who are antibody-negative. Similarly for boys and Mumps. And I have a particular downer on the majority unthinking reactions that seem common on Slashdot whenever this topic comes up.
