Study Suggests COVID MRNA Vaccines Help Fight Cancer Too

Friday, October 24, 2025

The COVID-19 mRNA-based vaccines that saved 2.5 million lives globally during the pandemic could help spark the immune system to fight cancer. This is the surprising takeaway of a new study that we and our colleagues published in the journal Nature.

More from the article ...

... While developing mRNA vaccines for patients with brain tumors in 2016, our team, led by pediatric oncologist Elias Sayour, discovered that mRNA can train immune systems to kill tumors " even if the mRNA is not related to cancer.

Based on this finding, we hypothesized that mRNA vaccines designed to target the SARS-CoV-2 virus that causes COVID-19 might also have antitumor effects.

So we looked at clinical outcomes for more than 1,000 late-stage melanoma and lung cancer patients treated with a type of immunotherapy called immune checkpoint inhibitors. This treatment is a common approach doctors use to train the immune system to kill cancer. It does this by blocking a protein that tumor cells make to turn off immune cells, enabling the immune system to continue killing cancer.

Remarkably, patients who received either the Pfizer or Moderna mRNA-based COVID-19 vaccine within 100 days of starting immunotherapy were more than twice as likely to be alive after three years compared with those who didn't receive either vaccine.

Surprisingly, patients with tumors that don't typically respond well to immunotherapy also saw very strong benefits, with nearly fivefold improvement in three-year overall survival. This link between improved survival and receiving a COVID-19 mRNA vaccine remained strong even after we controlled for factors like disease severity and co-occurring conditions. ...

fwiw, I'm not really thrilled with the first-person aspect of the article.

This is retarded. It's also a knee-jerk reaction to the spike in cancer since the shot became available.

See also the spike in clots and myocarditis since the shot became available that were linked to "long COVID" No one who thinks for themselves and has a healthy amount of skepticism believes this nonsense.

Hey stupid, keep flushing yourself with horse paste and let the rest of us take care of ourselves.

"See also the spike in clots and myocarditis"

I can't see it if you don't put a link. There must be a meta-study by now.

And "spike in cancer since the shot became available" is weak, when you could have gone with "Spike in cancer since Joe Biden stole the election."

You're too f*&^ing terarded to think, let alone think for yourself.

You're a prime example of why this country is circling the drain - people who can barely manage to live without society floating their a&^es thinks they have the ability to tell us how things should be run.

Meanwhile, you're ignorant as f*&^.

For example, the clotting issue was caused by AdV vector vaccines (Oxford and AstraZeneca) that were pulled from the market after about 150 cases emerged. There was never a clotting issue with the mRNA vaccines.

But this moron parrots it as if he has a clue because he's ignorant and proudly stupid.

So, your current trolling has got nothing.

As seems to be the usual?

Is it a spike in cancer since the shot became available, or a spike in cancer since COVID?

As far as I could find, the shot did cause some adverse reactions, so saying the shot caused damage was probably accurate. BUT, for pretty much every adverse reaction the shot caused, (like myocarditis,) getting COVID without the shot caused the same damage but much worse. So if you choice was only between getting the shot and not getting the shot, it is better to not get the shot. But that was not the choice. The choice was between getting the shot before getting covid, or getting covid without the shot. Because everyone ended up getting covid at some point. And in that case, as far as I have been able to tell, the outcomes for EVERY demographic was significantly better if you got the shot.

If you have evidence that shows to the contrary, I would love to see it.

And if one gets the flu shot and several other vaccines, one has a much lower chance of getting dementia. Kennedy is the worst appointment Trump has ever made, and that includes his three federal Supreme Court employees of the Trump conspiracy.

And the horse paste doesn't stop or slow down Covid, but at least one will be worm free. Last time I checked the 2 biggest supporters of the horse paste weren't doing so well. Rogan is shedding millions of viewers by the month and Pillowman is dead broke.

So the side effects are financial and not medical.

The aide effects are diarrhea (from maga morons mouths) and headaches (for those who have to listen to maga morons constantly blather nonsense about it) and a loss of perspective and common sense and a decay and destruction of democratic institutions.

If you're suffering headaches from my posts, take two Covid boosters and have your next of kin call me from the morgue. :)
