A second child died from measles-related causes in Texas last week.

It's part of a growing outbreak that's infected at least 505 people in Texas and has spread across 22 states.

Until this year, the U.S. had reported no deaths from measles in more than a decade.

Over the weekend, Health and Human Services Secretary Robert F. Kennedy, Jr., visited

Gaines County, the epicenter of the West Texas outbreak and spoke with families of both children

who died. Kennedy has previously resisted calling for widespread vaccinations, but on Sunday,

he posted on X, quote, the most effective way to prevent the spread of measles is the

MMR, or Measles Mumps and Rubella vaccine. The measles vaccine is considered one of the 20th

century's major advances in public health, and it saved an estimated 94 million lives in the last

50 years. The news hours, Dima Zane, recently sat down with someone who had a front row seat

to its creation. Measles was something that almost every child came down with at some point.

I was pretty miserable for a better part of a week.

In 1954, when he was just 11 years old, David Edmoniston would have never guessed that his very first blood test would change the world.

I was attending a boarding school in Massachusetts, and I came down with measles.

David and other students recovering from a measles outbreak were approached by a physician from Boston Children's Hospital, Thomas Peebles.

He told me that he was a member of a team who were developing a vaccine for measles.

And would I like to participate in that by giving some blood and throat washings?

And I was thrilled with the thought of being able to help thousands, millions of people.

A few weeks later, Dr. Peoples returned to tell David that they had isolated measles virus cultures

from his blood.

Did you realize how monumental that it was going to be?

No.
