Roald Dahl lost a child to measles. Here's what he has to say about the new outbreaks.

Olivia Dahl, shortly before her death from measles in 1962.

In 1962, the world was a remarkably different place: Neil Armstrong had yet to take his first steps on the lunar surface, John F. Kennedy was serving as president of the United States, and the Beatles were still a few years away from superstardom, having just recorded their first single.

The word “measles” was also a household name. Measles, which still exists in parts of the world today, is a highly contagious viral infection that typically causes fever, cough, muscle pain, fatigue, and a distinctive red rash. Measles was so pervasive around the world in 1962 that most children had gotten sick with it before the age of fifteen—but even though it was common, it was far from harmless. Measles killed around 400 to 500 people per year in the United States, and approximately 2.6 million people each year worldwide. Countless others suffered severe complications from measles, such as permanent blindness.

On today’s episode of Making Sense of Science, I’m honored to be joined by Dr. Paul Song, a physician, oncologist, progressive activist and biotech chief medical officer. Through his company, NKGen Biotech, Dr. Song is leveraging the power of patients’ own immune systems by supercharging the body’s natural killer cells to make new treatments for Alzheimer’s and cancer.

Whereas other treatments for Alzheimer’s focus directly on reducing the build-up of proteins in the brain such as amyloid and tau in patients will mild cognitive impairment, NKGen is seeking to help patients that much of the rest of the medical community has written off as hopeless cases, those with late stage Alzheimer’s. And in small studies, NKGen has shown remarkable results, even improvement in the symptoms of people with these very progressed forms of Alzheimer’s, above and beyond slowing down the disease.
