Measles and measles vaccination in isolated Amerindian tribes. II. The 1978/79 Xingu epidemic.
Vaccine induced measles antibody titers in the Upper Xingu Indians remained at satisfactory levels without evidence of decline over a period of six years without re-exposure. However, in another area, a vaccination program which used a reduced dose of vaccine was only 63% effective. When measles virus was introduced to the latter area a protracted epidemic ensued with 23% of the population becoming ill and six deaths. The deaths occurred exclusively under 13 months or over 40 years of age.
