Measles: Two US outbreaks are attributable to low vaccination rates

Measles outbreaks on the east and west coasts of the United States have been attributed to low vaccination rates and imported cases. More than 200 cases have been reported, including several hospitalizations but no deaths.

Most cases occurred in persons who were not vaccinated against measles, mumps and rubella (MMR vaccine) or who did not receive the two recommended doses at the age of 10 months. 12-18 months and 4-6 years. Most states allow parents to rely on religious reasons to avoid the required vaccinations for day care or school attendance, but 18 states allow parents to opt out for philosophical reasons.
