Outbreak MMR Vaccination Recommendation
November 13, 2017

During the current mumps outbreak in Hawaii, in addition to routine vaccination recommendations, adolescents (aged 10-19 years) and adults (born in 1957 or later) should receive an additional MMR vaccine dose now.

The outbreak dose of MMR vaccine is recommended, regardless of:

  • Previous age-appropriate vaccination; or
  • Documentation of positive mumps IgG titer – a positive titer does NOT reliably indicate immunity to mumps disease; therefore, do NOT obtain titers prior to vaccination

The outbreak dose should be separated from administration of a previous mumps-containing vaccine by a minimum interval of 4 weeks.

A person should receive no more than 3 total doses of mumps-containing vaccine.

Yellow Fever in Brazil 
March 20, 2017

Since December 2016 there has been an ongoing outbreak of yellow fever in several states in Brazil. In response to the outbreak, the Centers for Disease Control and Prevention (CDC) has issued a travel alert (Level 2, Practice Enhanced Precautions) for certain areas of the country.

It is recommended that anyone 9 months or older that are traveling to these areas should be vaccinated against yellow fever. People who have not been vaccinated should not travel to areas with ongoing outbreaks. Booster doses of yellow fever vaccine are no longer recommended by CDC for most travelers, however, booster doses may be given to travelers who received their last dose of yellow fever vaccine at least 10 years ago and who will be traveling to high-risk settings. Travelers should consult with a yellow fever vaccine provider to determine if they should be vaccinated.

For updated information on the outbreak, including identification of affected areas in Brazil and CDC recommendations, visit CDC’s Travelers’ Health page – Yellow Fever in Brazil.
