I received the standard US Navy vaccinations when I was on active duty. That included the mumps vaccine.
I didn’t need it, really, because I had the mumps as a kid.
But as everyone knows (or should know), vaccines are not nearly as effective as the antibodies you get from having had the actual disease.
Now this about an outbreak of mumps on a navy ship with 100% vaccination rate.
The USS Fort McHenry, a dock landing ship, has been stuck at sea for months, along with hundreds of Marines and sailors aboard after dozens of crew members contracted mumps. The ship remains quarantined as officials with the Navy and Marines Corps Public Health Center conduct an in-depth epidemiological investigation.

Every single person aboard the USS Fort McHenry has been vaccinated against this virus, yet dozens have been infected. Even after more booster vaccines were administered, more cases of the vaccine-preventable virus appeared.
…
“The Navy’s position is that vaccines are effective at reducing the incidence and severity of vaccine-preventable diseases,” BUMED told BI. Unfortunately, “the mumps portion of the measles, mumps, and rubella (MMR) vaccine is the least effective of the three components, providing 88% effectiveness after completion of the two dose series.”
