The CDC​ is now backing an additional measles vaccine​ shot for some travelers within the United States in response to record outbreaks.

Measles infections after vaccination are rare, and there are no documented cases of healthy, fully vaccinated people dying from the virus.

HHS Secretary Robert F. Kennedy Jr. now says vaccination is best the prevention as more than 650 people in the U.S. are infected with the disease.

The Cleveland Clinic notes that there is no cure for measles, and measles just has to "run its course." However, the best protection from it is a measles vaccine, which is typically given to babies in the form of the MMR (measles, mumps and rubella) vaccine.

A board-certified family medicine physician explains what a measles vaccine booster is, who should receive it as an adult, and why they may wish to consider it.

A measles outbreak in Knox County, Ohio, grew to 14 cases this week, with the state's overall count in double digits across four counties. The U.S. has more than double the number of measles cases it saw in all of 2024,

The number of measles cases exceeded 500 in Texas on Tuesday, according to the state’s health department, which made the update days after a second Texas child died after contracting the highly contagious illness that has been confirmed in at least 20 states.

A former surgeon general is “particularly concerned about the accessibility of vaccines for vulnerable populations.”
