One in a series. I feel kinda badly about quoting so much from one (peer-reviewed) article.
http://www.journals.uchicago.edu/doi/full/10.1086/377712?cookieSet=1 Journal of Infectious Diseases, 2004
Measles vaccination is one of the most cost‐effective health interventions ever developed. Without the vaccine, 5 million children would die each year from measles-assuming an estimated case‐fatality rate of 2%-3%. Without measles vaccination, the costs of caring for those with measles in the United States would be $2.2 billion annually, and the indirect costs would be an additional $1.6 billion [235]. Each dollar spent on measles vaccine saves $12-$17 in direct and indirect costs.

Other quotes:
Measles is transmitted by the respiratory route and is highly infectious. Infectivity is greatest in the 3 days before the onset of rash, and 75%-90% of susceptible household contacts develop the disease.

http://www.journals.uchicago.edu/doi/full/10.1086/377712?cookieSet=1 Measles case‐fatality rates have declined in association with economic development and associated decreased crowding, older age at infection, improved nutrition, and treatment for secondary pneumonia.
BUT
During the past 13 years in the United States, the case‐fatality rate has averaged 3 per 1000 reported measles cases. (It was down to 1 per 1000.)
In developing countries: Measles remains a leading cause of death and disability‐adjusted life‐years lost.
