Would be nice to live in a world where criminals weren't exalted though.
I don't exalt them, not by a long shot, and I certainly encourage vigilance against any and all organizations that have managed to accrue
any kind of power. I simply accept that self-interest
usually keeps them from the more overt and boneheaded forms of villainy...like trying to fake data to sell billions of dollars of high-profile product to the governments and populations of wealthy nations in circumstances where an ineffectual or harmful product would be quickly and clearly revealed for what it was. Such scams are saved for markets that no one with power cares about, or circumstances where it's easy to hide.
A vaccine that doesn't work is blatantly obvious when infection rates among the vaccinated don't fall to where they should be. A vaccine that is harmful is blatantly obvious when people start to get sick after a vaccination campaign. Even organizations that wouldn't bat an eye at the thought of facilitating the most horrific actions are not going to commit financial suicide by messing with vaccines. No amount of extortion, bribery, or lobbying is going to buy one's way out of that kind of screw up.
I cannot prevent anyone else from mistaking self-interest for altruism or some other virtue. Nor am I going to lead a boycott of a product I have a need for, exposing myself and others to tangible harm, just because I don't like the values of those peddling it.
However, I will happily advocate against excessive intellectual property 'rights' that allow profiteering off disease.
My first question would be, before rolling up my sleeve, would be, how do they prove that dose, is genuine? Everything, worth anything, has been faked and sold, in the millions.
Just a thought.
Probably best to ask your physician if you have any concerns, but I know these products have serial numbers, tamper evident/resistant packaging, random inspection/tests of batches, etc.
Go to any legitimate healthcare provider and there will be a paper trail for everything. Risk/reward for trying to distribute a fake, mass produced, vaccine in quality healthcare system would not be favorable, and the losses would mostly fall on insurance providers who have strong incentive to ensure it doesn't happen often (by mandating certain procedures and aggressively prosecuting fraud).
Not saying there won't be small scale fraud at the individual practice level (where most supply chain checks have already been done and swapping out a product is easier), or that it will be hard to find fake/substandard products for sale, but if you go to a reputable practice in a developed nation, you almost certainly have very little to worry about. Just stay away from quacks and don't order stuff through gray-market sources.
Less developed areas may well have much more serious problems in this regard, however.
