This isn’t exactly correct. 2 MMR doses are 97% effective at preventing infection- enough to drive measles out of circulation if enough ppl are vaccinated due to HERD immunity. But if herd immunity is broken, you still have a small chance of becoming infected if it’s circulating widely. So mask up

Measles Vaccination
Learn about measles vaccine basics, who should get it, when to get it, and why it's important.
It IS true that the measles vaccine is quite different from the Covid vaccines in that our Covid vaccines do not prevent infection effectively enough to create a “herd immunity” barrier like the MMR vaccine did, drive COVID out of circulation. HOWEVER, early data back in 2021 showed that (1/?)
The MRNA shots WERE very effective at preventing infection, and Biden’s policy AT THAT TIME was one AIMED at achieving herd immunity, of the type we now have w measles and other (mostly) eliminated diseases. That’s WHY vaccine mandates existed. That’s WHY vaccine passports existed
I wrote here about how the press bait-and-switched the public as it became clear that this Covid herd immunity would never materialize. The goalposts of pandemic success were repeatedly moved, until somehow success became “everyone get reinfected forever”

How the press manufactured consent for never-ending COVID reinfections
Continual reinfection was not the "new normal" Biden advertised. How did we get here?
Herd immunity to Covid crumbled for two reasons: 1) waning efficacy of the vaccines; they have a durability problem 2) new variants. Once delta popped up and then omicron, our vaccines were too genetically distant to protect ppl well.

Does the public understand that "variant" means "vaccine resistant"?
Getting boosted is critical because the virus is changing. Other forms of mitigation are critical to slow the rate of change.
Just a small correction, The MRNA shots were NOT effective at preventing infection in 2021, or ever. None of the tests for the vaccines were ever trialed w immunocompromised people nor did they ever even track to ensure ppl weren't getting infected. The govt knew this and encouraged ppl to unmask
May 7, 2025 03:18Heard immunity didn't crumble bc of the vax, heard immunity has always been impossible w Covid bc of the proliferation of variants & bc we never had anything close to a sterilizing vaccine. Even vax that are variant matched do not meaningfully prevent infection bc they don't induce mucosal immunity
No, they were briefly good at preventing transmission! They just took very early data and ran with it, not realizing that the virus would mutate around this protectiveness incredibly quickly. But it did provide good protection for the first several months
www.pfizer.com/news/press-r...This is I think important to know bc there are a lot of lies around the idea that politicians never claimed this- but it literally was true! They did prevent infections quite well on their initial release, but it was irresponsible to assume that would hold up and to not support them w NPI
And when delta hit is when they should’ve abandoned the herd immunity strategy , but had too much riding on it politically, so essentially they just said fuck it and began lying through their teeth
No, but even here it says only 7 days and they were doing those trials with supportive measures like mask mandates etc in place. They also never trialed the vaccines with immunocompromised folks nor did they account for waning! Then they never tracked infection long term.
I think it's really important to note that they never actually had the data to support the claims that the vaccines prevented infection and (yes totally agree with you that they just lied). But none of the vaccines have ever induced any sort of sustained mucosal immunity to prevent infection
(I totally agree with you btw that by the spring and when Delta hit in early summer it was clear even to the public that heard immunity was impossible. But they should have never made those claims to begin with imo when they didn't have any real world data to back it up)
Wait sorry one last post I promise (sorry I should just text you lol) but as soon as ppl began getting vaxed they were getting breakthroughs. U can see this in news reports from February 2021. There were countless cases like this but the media was getting intense pressure from the govt not to cover

Four people in Oregon who received both doses of vaccine test positive for coronavirus
There are two cases each in Yamhill and Lane counties, the state's Health Authority said.
Breakthroughs though will always happen - like w measles my pt was, 97% is not 100%. 3/100 is even rly that low or rare. You might be in the supermarket w 100 people tomorrow, all of you could be vaccinated and 3 of you could still get the measles !
I still think Biden admin just as culpable, they should’ve had statistical modeling to work out like how fast does it spread, how fast is it mutating, if we bring down these NPIs how much breakthrough do we see, how fast do we break these vaccines. They didn’t rly care they took the easy route
Yuppppp 100000% and now we're all going to suffer and die bc they manufactured consent for endless disease 😭
