In a significant shift, U.S. health officials have revised their recommendations regarding measles vaccinations for international travelers. The new guidance from the Centers for Disease Control and Prevention (CDC) now advises all Americans, regardless of their destination, to ensure they are vaccinated against the measles virus. This update reflects growing concerns about measles exposure not only in countries facing outbreaks but also during air travel.
Previously, the CDC emphasized the necessity of receiving the measles-mumps-rubella (MMR) vaccine primarily for travelers heading to regions experiencing outbreaks. However, as of last week, the CDC has expanded its recommendations, urging all travelers to get vaccinated before embarking on any international journey. This change underscores the increasing risks associated with measles transmission during transit.
Ashley Darcy-Mahoney, a researcher at George Washington University’s nursing school, highlighted the significance of this updated guidance. She pointed out that a recent outbreak in Colorado was linked to an international flight that landed in Denver, indicating that exposure can occur regardless of the traveler's destination. “We’re seeing a shift from localized outbreaks to transmission in transit,” Darcy-Mahoney explained, noting that the CDC's response aims to address this evolving situation.
The CDC’s travel notice now advises that all Americans aged 1 and older should receive two doses of the MMR vaccine. Additionally, infants aged between 6 months and 11 months who are traveling are recommended to get an early dose. This proactive approach aims to bolster immunity and protect against potential measles outbreaks as the number of reported cases in the U.S. has exceeded 1,000 this year.
