Japan finds stainless steel particles in suspended doses of Moderna vaccine

Note that they don't believe it posed any additional health risks, they identified the issue that caused it and believe it affected single batch: "All the vials came from a single lot, but shots from two other lots from the same Rovi manufacturing line were suspended as a precaution." So likely nothing to worry about at scale.

Why are you so confidently advocating for a "safe until proven unsafe" mentality here? The health impacts from this contamination are completely unknown, and could impact a lot of people, and their children, etc.

EDIT: down vote all you want, armchair reasoning does not prove that this contamination is safe - cite some relevant scientific literature to support your claims

Because the vaccines are political now, so there isn't any room for uncertainty. You're either for or against.

There are ways to predict what will happen besides randomized controlled trials.

Care to elaborate? Is there any scientifically backed rational for confidently “predicting” there will be no health risks caused by this contamination? No one here has provided any citations yet.

I suspect you're being downvoted by people who simply recognise your username at this point. It's disappointing because I think your comments for the most part are fine, people just seem to take offence to you not being a vaccine zealot.

In doing my part to stick to the topic at hand, I tried to find some research which supports these claims about stainless steel. It seems like Nickel is typically a component of stainless steel and is generally not something you want to have in your body[1].

I'm also not sure how the additional iron, presumably being processed by the liver, might affect someone who has cirrhosis.

I assume "nothing to worry about at scale" really means "not likely to immediately kill a bunch of people".

Thanks for the feedback and the citation, that was an interesting read.

Here are a couple more good papers I skimmed through today while looking into this topic. I agree on the "not likely to immediately kill a bunch of people" point. From what I can tell, there are very few longitudinal studies evaluating the health outcomes from metallic corrosion and wear from implants.

Citing [1], stainless steel corrosion is associated with "distinct inflammation and tissue reactions in the surrounding soft tissue with high amounts of particles".

What's being advocated here?

The batch is being recalled. They think it's nothing to panic people who have received it based on us having decades of blood-contact data for stainless alloys.

If you're going to attack the messenger, at least read the message.

Stainless steel? Wait until the people scared of vaccines find out what's in tattoo ink. What's the overlap between tattooed and vaccine hesitant?

From Takeda's statement, it's 316 stainless steel.

guess it still doesn't make your blood magnetic then

I imagine stainless steel particles are in a lot of things. I, like many others, use stainless steel silverware, cutlery, pots/pans, sinks/faucets, etc..

If stainless steel is worrisome, then I feel like one or two injections is probably the least of concerns at this point. Then again, I'm just an ignorant person with a keyboard and internet access, so what do I know?

I hope that you’re aware injecting air in your vein may potentially lead to your death in a short amount of time ?

Vaccines go into muscle, not blood vessels.

It's still much better for everyone involved to not stick air into your muscle, though.

Any air accidentally injected into a vein as part of a vaccination would be insufficient to cause injury. It takes tens or hundred of milliliters of air to cause a venous embolism in a typical person.

Covid vaccine syringes are 1 ml. It's impossible to inject enough air using one of these syringes to cause any sort of trouble.

Terrible news to get now, at what I would reckon is the peak of the anti-vax movement so far. Today a huge crowd of people blocked ambulances that were arriving at the hospital in my city, protesting vaccines. I have rarely witnessed such idiocy here, certainly never on such a massive scale. This story about metal contaminants will surely become part of their twisted repertoire.

Magneto is that you? https://www.youtube.com/watch?v=LAcs2uROaoI

Can’t wait before the anti 5G crowd sees this and the “told you so’s” start happening.

I wish I could get a 5G implant. Maybe my signal would be better? ;)

Pretty disturbing to see this comment from Takeda and Moderna: “Stainless steel is routinely used in heart valves, joint replacements and metal sutures and staples. As such, it is not expected that injection of the particles identified in these lots in Japan would result in increased medical risk.”

Do they think that most people are too stupid to realize that injected particles are very different from a stationary heart valve?

A stationary heart valve (and other implants) will "lose" particles due to ware over time.

Can you provide any citation supporting this claim?

Are there longitudinal studies proving that these particles do not pose a health risk?

Any material is going to wear out over time if a liquid continuously runs over it. The worn-out particles have to go somewhere

They're not going to be used. So no health problem.

Is there any point in banging on about it?

>About 500,000 people have received shots from the three suspended Moderna batches

Of course, but those particles will be vastly smaller than any burrs from a machine.

"September — Japan announced that it would not approve Corovax for use in Japan in favor of developing and producing its own vaccine."

Man I wish the writers would stop dragging this storyline out over multiple seasons. Change the channel.

For those confused, the above quotation is from a hypothetical scenario, and the Corovax mentioned is unrelated to the Covid-19 vaccine of the same name from Novavax.
