Says the CDC:

About 1 in 5 people in the U.S. who get measles will be hospitalized.

Also the CDC, 1 in 62 or 1.6% of those with measles were hospitalized:

In the decade before 1963 when a vaccine became available, nearly all children got measles by the time they were 15 years of age. It is estimated 3 to 4 million people in the United States were infected each year. Also each year, among reported cases, an estimated 400 to 500 people died, 48,000 were hospitalized, and 1,000 suffered encephalitis (swelling of the brain) from measles

Can someone please reconcile those two contradictory statements from the CDC?

I had measles as a kid, probably in 1963 or 1964. I did not receive a vaccine until 2021 – no one ever said anything about a measles vaccine until I asked my doctor. A titer test showed that I had previously had measles and mumps but not rubella, so I received a single dose of the MMR vaccine.

Apparently, as kids, even if we previously had measles, we were supposed to have gotten an MMR vaccine once they were widely available, and many were advised to get a 2nd dose of the MMR vaccine later. No health care provider ever said anything about MMR so I went through life having had measles (before the vaccine was available), but never even having an updated shot.
