Remember, due to a law from the 1980s there is virtually no way to sue the vaccine manufacturer if you or your child has a serious adverse reaction to a vaccine. You have to hope you get some compensation from the national vaccine board. http://www.hrsa.gov/vaccinecompensation/
So what incentive remains for a for-profit Big Pharma company to make vaccines safer?
Surveys suggest vaccinated kids are suffering higher rates of many medical conditions than unvaccinated kids. Now that California and a few other states have laws forcing nearly all school-age kids to be vaccinated Big Pharma will be frantic to get a similar national law. If they fail, in a few years there will be statistics comparing the health of kids in various states. //www.curezone.org/forums/am.asp?i=2266432
Are vaccines being used to influence population rates? Stressed out parents of sickly kids are not as likely to have as many kids and those sickly kids are not as likely to have as many children as their healthy peers.
