I remember a doctor telling me that the missionaries and doctors who go into villages in the third world provide potable water, wash the people, their food, clothes, eating utensils, burn and replace their bedding, teach hygiene, boost the nutrition of these poor people,
AND then, at long last, line these poor people up and give them vaccines.
AND the vaccines get all of the credit.
In the very last smallpox epidemic in Yugoslavia in 1972, vaccinations were given, BUT quarantine was strictly observed. So which public health measure was most effective?
Vaccination never works alone. Vaccination relies on other variables to be successful, but vaccination alone always gets the credit, because doctors invented it.
"Vaccines are like a box of chocolates. You never know what you're gonna get - acute hemorrhagic edema of infancy, allergies, diabetes, eczema, petit/gran mal seizures, ADEM, AFP, ASIA, CFS, GBS, JPA, JRA, LGS, LKS, MS, POF, POTS, RA, SJS, SLE, SPD, TPI, Henoch-Schonlein purpua, fibromyalgia, Retts Syndrome, encephalitis, Hughes Syndrome, neurological damage, coma, or death."
