A Disease runs through cycles, it appears for say 50 years then goes away,then it may return. Just look at any of the large killers in the past. Many of the disease go away when people start living a more sanitary life. That is why i say plumbers and garbage collectors have done more to extend the life span of humans than doctors have.
The funny thing is when the polio vaccine came around the children that got the vaccine and still got sick were told they had aseptic meningitis, not polio. So the rate of aseptic meningitis rose in some states by up to 400% on the east coast. See the vaccine worked, the MD's just renamed the illness and the rate of polio decreased.
The money scam is not as much on the physicians side as it is on the Pharm side. The pharm companies make billions from vaccines every year, they just pimp the product through a bunch of guys that do what they are told. Why should the MD's question it anyhow, it is a great source of patient flow. Kind of like a pimp and whore relationship, the whore just does what she is told (guidelines) or she gets beat up (license revocation).
