Skepticism, Science & Pseudoscience

From 1958 to 1962, the United States had an average of 503,282 cases and 432 deaths each year ... In large cities, epidemics often occurred every two to five years. When the measles vaccine came on the market in 1963, measles began a steady decline worldwide. By 1995, measles deaths had fallen 95 percent worldwide and 99 percent in Latin America. In the United States, the incidence of measles hit an all-time low in 1998, with 89 cases and no deaths reported. There have been several epidemics in the United States since 1963: from 1970 to 1972, 1976 to 1978, and 1989 to 1991. The epidemic of 1989-1991 claimed 120 deaths out of a total of 55,000 cases reported. Over half of the deaths occurred in young children ... http://science.education.nih.gov/supplements/nih1/diseases/activities/activity5_measles-database.htm

It looks like the US incidence rate for rubeola has fallen by a factor of about 4000 in the last 50 or 60 years and by a factor of nearly 500 in the last 40 years. The US incidence rate for rubella has similarly fallen by a factor of 2500 or more in the last 40 years
