The study of the measles incidence rates and the vaccination rates in the USA showed that there was a clear pattern of increasing immunisation rates followed by declining incidence rates. The opposite pattern was also true (decreasing immunisation rates increased the number of cases). Detailed figures were available in the article.

The measles incidence (cases/100,000 population) relating to the pre-school vaccination rates varied from 13.2 (40 to 49% pre-school vaccination rate) to 0.001 (70 to 79% pre-school vaccination rate).

The proportion of measles cases with meningitis was 0.1%.

The proportion of patients with meningitis who had permanent disabilities was 25%.

The proportion of patients with meningitis with slight permanent disabilities was 20%.

The life expectancy at age 2 was 74.1 years.

The life expectancy for children with slight disabilities was 74.1 years.

The life expectancy for children with moderate disabilities was 64 years.

The life expectancy for children with severe disabilities was 4 years.

The proportion of cases that died was 0.3%.

The utility rate was 0.1 for the slight disability state, 0.6 for the moderate disability state, 0.9 for the severe disability state, and 1 for death.

The proportion of measles cases occurring in people aged 18 years or older was 27%.

The proportion of preventable measles cases was 32% (long-run average).
