@CuriousMagpie @overholt
I *also* had to get the full MMR series a second time, because my titres showed no immunity. This is so important!@anathema @CuriousMagpie @overholt did not realize it could lose effectiveness that much, and really not this early in life. Good idea to check out soonish.

@overholt I can't get vaccinated here b/c the system claims I'm immune b/c of my age.
I continue to mask in public, but still.

@overholt happened to me with whooping cough, which turns out to be less fun than it may sound

@scottmiller42 @overholt I got my chickenpox and measles mixed up. My mistake

@overholt consider getting the SHINGRIX vaccine for Shingles too, which will also protect you against Ramsay Hunt Syndrome. I had that, you don’t want it.

It's not your age, at least that's not the whole story.
In your age group, you only got vaccinated once - it was believed to be sufficient back then. Today, there are two measles vaccinations which has been proved to be much better/longer lasting.
Still, the result is the same - better get vaccinated one time more often than not!

@overholt We looked back through my records recently and discovered there was no record of my MMR, so I got one. (Mom would have been very pregnant with my sister at that point, So it's not shocking it fell through the cracks.)

@overholt
Something I learned from a pharmacist (I'm in a cohort just a bit older than you, and was unsure if I'd been vaccinated as a child) is: when in doubt, get the vaccine — an extra dose is not a problem (one extra dose ≠ overvaccination, with many doses of the same vaccine).

@stevenray Already did!

@overholt my husband just did that
of all the things we don't need, measles is high on the list!

@overholt Got an MMR booster last fall (2024) as well. With overall population vaccination levels being too low to stop outbreaks, the next best option is for those who are vaccinated to ensure their immune response is strong and not waned over multiple decades.

@overholt Another good reason to also get the Shingrix shot. There's some evidence that it's protective against dementia.

https://www.chop.edu/vaccine-education-center/vaccine-safety/other-vaccine-safety-concerns/dosing-safety@RunRichRun @overholt I'm probably slightly older than either of you and I expected that Kaiser would give me a new pair of shots to supplement my single early-1960s one without question but they insisted on checking my titer and in fact I had no immunity. I might have had mild side effects but nothing literally memorable.

@overholt This is really interesting. I'm wondering if anyone who's replied is in the UK? We can't just request vaccines on the NHS, for example I wasn't eligible for a free flu jab this year, but this is something I could look into getting done privately, esp as I have a health plan through work instead of a pay rise

@callunavulgaris @overholt I got measles vaccination at Boots just a few weeks ago, cost was about 30 pounds I think.

I was born mid 60’s and just got the vax again. No sense risking it!

@overholt I am reading responses to this thread and would like to refer people to the CDC website on FAQs regarding whether or not adults need more than 2 MMR vaccines. Most adults do not need more than 2 MMR vaccines and titers are NOT recommended. The exception is for adults vaccinated with the killed vaccine between 1963 and 1967: https://www.cdc.gov/measles/hcp/clinical-overview/questions.html

@overholt i got tested recently in my early 40s and apparently i still have immunity. i would have preferred to just get a booster, but my dr didn't want to do that.

@overholt I attended a clinician CDC webinar update on measles on 9/11/25 and asked this titer question specifically. The CDC response was: “CDC considers most people with documentation of 2 doses of MMR received after 12 months of age, and separated by at least 28 days, to have evidence of measles immunity…” 1/2
