You tell me. I'm not a Dr., but if there's a potential for one in 100,000 child deaths from a vaccine, don't we owe it to those children to develop a test that would identify incompatible antigens(?) or whatever it is that causes the body to react in a lethal way to the vaccine?
Or are you stating that you do not believe any of these vaccines ever cause a reaction as bad or worse than the disease they immunize against? Don't give us this BS that "you can't prove it", when recorded medical cases never refer to or investigate vaccines as a potential cause.
It is proven already by the drug companies themselves and the National Vaccine Compensation Program...the vaccine inserts say that taking them can cause viral shedding in some cases where a vaccinated person could be the ORIGIN of an outbreak...it also says that vaccines can cause narcolepsy, encephalitis, etc...just like all prescription drugs...and the fact the drug companies are EXEMPT from law suits means that their inserts are not just legal CYA jargon...
