4Severe cases of 5measles can also cause 6blindness, 7pneumonia or 8swelling of the brain and in some cases, death.

"We're seeing these 9sporadic outbreaks of measles."

Dr. Daniel Kuritzkes with Brigham and Women's Hospital says most of the measles illnesses now 10popping up in the U.S. are in young children.

Last year, 285 cases were reported to the CDC. That's the most since 2019.

And this year, cases are already 11emerging in several states.

Experts say it's due to lower vaccination rates from misinformation.

In Texas, there's an outbreak with at least two dozen cases, and state health officials say that number is growing.

"The vast majority are happening in people who have either not been vaccinated or whose vaccination status is unknown."

Kuritzkes says the best protection against measles is vaccination.

The first dose is typically given to children between 12 and 15 months, with a second dose 12administered around age 4.

The CDC says older children and adults can also get vaccinated if they didn't receive the vaccine as a child.

And the agency says if you were vaccinated with the first version of the measles vaccine used between 1963 and 1968, or don't know which type of vaccine you received you should get at least one dose of the current measles vaccine.

"People should just make sure that they are up to date with their measles vaccination and that their children are 13up to date."
