US: CDC expands measles vaccine guidance for all international travel

The CDC has updated its measles vaccination guidelines, now recommending immunization for all international travelers, regardless of destination, the Independent reported. The agency advises two doses of the vaccine for everyone aged one and older, and a dose for infants aged 6–11 months who are traveling abroad.

The change follows rising measles cases in the U.S., including outbreaks linked to international flights. Health experts say the shift reflects growing transmission risks during travel, not just in countries with known outbreaks. Over 1,000 U.S. cases have been reported this year, highlighting the need for stronger preventive measures.
