"For the rest of you, listen up. This is NOT a science problem, it is a crime problem. The criminals are doctors and public health officials who know full well what is going on and refuse to take any effective action to control it.
Adult, mercury preserved, vaccine is a zillion times cheaper than pediatric mercury free vaccine. The criminal quacks in charge continue their genocide by chanting "MERCURY IS PERFECTLY SAFE IN VACCINES!!!!" Since medicine is a liberal art instead of a legitimate technical field, you don't get what would happen in chemistry or engineering or physics where some people would do the appropriate calculation (which the EPA did, and published), show it to others, and everyone would be convinced the amount in the vaccine schedule (admittedly as of 1999, surreptitiously now) necessarily causes brain damage to a lot of children.
Since doctors can only really take the word of other more important doctors and officials for the most part, a lot of them do believe mercury is safe even in wildly toxic amounts when a DOCTOR administers it and doesn't mean to hurt anyone. Yes, this is a psychotically insane belief. Yes, psychosis is induced by going to medical school. BTW, Naturopaths actually have classes in being psychotic. This is a necessary consequence of letting medicine be a liberal art (as opposed to letting liberal arts majors who are willing to buckle down and learn technical stuff attend medical school, which would be fine).
The consequence of all this is that many physicians use the adult, preserved vaccines for children. In almost all cases, the adult and pediatric vaccines are the same as far as antigen, adjuvant, etc. Pertussis is the one exception. The adult vaccine (a booster) is not potent enough to cause immunity when used as the initial vaccine or first booster in children.
So a large number of children do not have immunity to pertussis, despite being vaccinated. That's why the epidemics are back. It has nothing to do with people not getting vaccinated. It has to do with negligently genocidal doctors using the wrong vaccine to save a few bucks because their overtly genocidal superiors told them it was OK."
Word of wisdom from me...
"... It has to do with negligently genocidal doctors using the wrong vaccine to save a few bucks because their overtly genocidal superiors told them it was OK." It has to do with vaccines period."
There is NO RIGHT vaccine. Never was. EVER. ANY vaccine is wrong. PERIOD. Get it yet?
Riddle me this: If vaccines work, why do people always say they don't want their vaccinated children around un-vaccinated children? ~ Truth Teller
