Be careful when you advocate mandatory medical procedures. It can be very dangerous. In 1945 there were about 10 vaccinations recommended for children before age 6. Today, when you count all the booster shots, it's about 200. The benefits of flu vaccines is very questionable (they didn't even include the most prevalent strain in this year's vaccine), and with the pace of medical research it will only grow. There is a long list of FDA-approved drugs that have been withdrawn once it was discovered how dangerous they were in the general population. Perhaps worst of all is the total immunity from liability afforded to all the pharmaceutical companies for approved vaccines. They are not even held accountable if something goes wrong.
I am not anti-vax. Most vaccines are important, and I think it's good that most schools require children to get the important vaccines before they are allowed into the schools. But it can certainly go too far, and the Gardasil requirement mandated by Rick Perry for Texan 12 and 13 year-old girls is a perfect example (note the executive order was NOT approved by the legislature, and Perry received large donations from Merk, the company with the patent for Gardasil).
I have to agree with Rand that there should be ways for individuals and parents to opt out, especially for the less critical vaccines.
