Moderna and Merck’s Skin Cancer Vaccine Succeeds in Late-Stage Trial — Stock Soars 177% in a Single Day

Moderna and Merck announced on the 19th that their jointly developed mRNA cancer vaccine met its primary goal of suppressing cancer recurrence and metastasis in a late-stage (Phase 3) clinical trial targeting malignant melanoma, sending Moderna’s stock soaring 177% in a single day.

While the thread buzzed with excitement over this new cancer treatment technology, some voiced skepticism — pointing to the sky-high price tag inherent to a personalized treatment (with guesses around ¥9.99 million, roughly $67,000) and the fact that the demonstrated benefit was limited to “extending time to recurrence.”

Moderna and Merck’s Skin Cancer Vaccine Succeeds in Late-Stage Trial… Stock Jumps 177% in a Day

U.S. pharmaceutical companies Moderna and Merck revealed on the 19th that their jointly developed messenger RNA (mRNA) cancer vaccine achieved its primary goal of suppressing cancer recurrence and metastasis in a late-stage (Phase 3) clinical trial involving patients with malignant melanoma, a type of skin cancer.

This marks the first time a personalized cancer treatment built on the mRNA technology used in COVID-19 vaccines has produced positive results in a large-scale Phase 3 clinical trial.

>Messenger RNA (mRNA) cancer vaccine

Ha, this is exactly the kind of news that'll send the anti-vaxxers into another meltdown lol

The dawn of the cancer vaccine era.
It's a straight line running from the PD-1 antibody breakthroughs all the way to this.

The era where even cancer becomes treatable and preventable is finally here. Humans have already reached the point where minor illnesses don't kill us anymore, so basically we don't die unless we get cancer — and now even that's falling. Once cancer is mostly solved, dementia is next. The elderly population is going to explode.

That said, since it's a custom-made vaccine, the price tag is going to be in the tens of millions of yen.
It's not a treatment everyone overseas will have access to, and in Japan it'll just become another high-cost medical care headache.

It won't cost that much — more like around ¥9.99 million (roughly $67,000).

Good luck, Japan's guinea pigs (i.e. test subjects).

Things you can do on your own:
Don't live a lifestyle that promotes abnormal cell growth
Avoid synthetic detergents, fragrances, etc. as much as possible
Use good-quality oil and salt, and make sure you have an easy way to get a variety of polyphenols

Eating plenty of fruit and vegetables lets your gut bacteria — whose collective genes outnumber your own 100 to 1 — pump out the metabolites that keep your immune cells running at 100%

That's just efficient — it helps with everything, not only cancer, so it's the best value you can get

Even calling it "custom-made," it's probably just like synthesizing a DNA primer, right?
Wouldn't it end up being like ¥20 per base with next-day delivery?

I bet mRNA vaccines for every kind of cancer will exist within 10 years.
50% of Japanese people get cancer, and cancer is far more dangerous than COVID.
The "vaccine believers" (a mocking term for staunch vaccine boosters) who trust mRNA vaccines as safe and effective should absolutely get this one.
If they don't, they're admitting they were just fools who got played.

Japanese pharma companies… what are you even doing?

Maybe it'd be best if the rich rushed to get it first.
