PSA: If you are older than ~30 you may have only received 1 dose of MMR vaccine (which includes measles), and should consider a second one. I have not done the EV math on this.
in 1989 the Advisory Committee on Immunization Practices (ACIP), the American Academy of Pediatrics (AAP), and the American Academy of Family Physicians (AAFP) all shifted from recommending 1 dose of the MMR vaccine to 2, with the second dose coming between 4-6 years old, because of outbreaks in adults who received only 1 dose. This means almost everyone who was 7 or older in 1989 received only one shot, people between 1-6 in 1989 may or may not have received a second, and I’m unclear how fast pediatricians adopted the standard so I’m not sure what the chances of a second shot are for people between ~30 and 35.
A third shot is generally considered harmless but if you’re being cautious it’s possible to check your childhood vaccine records. I was able to get mine from my school district; if your pediatrician’s office is still around you can also try them.
I wanted to publish this with actual math on the costs and benefits, but the post was suffering from serious feature creep and I at least wanted to get this one fact out there quickly.
