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

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".

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.

[criticaltinker]

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.

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.
