So, even if you are in danger of death or disability from a hideous, and often fatal disease, and there was a very effective vaccine against that disease available to you free of charge (all of which is true), you would refuse the vaccine because you are primarily interested in the stock price of the company? Stopping the company from making a profit is more important than stopping a disease that brought the world to a screeching halt, at least it did before the vaccine came along?
Or, to look at it another way, what was the stock of the Ford Motor Co. worth, before the automobile was invented? What was the stock of Amazon, Google, or Apple worth before modern technology came along?
Maybe not a 100% perfect comparison, because those other companies aren't actually saving lives, where the pharmaceutical companies are. That's not to say the pharma companies are perfect. They did make plenty of money off the opiods also. But hard as the politicians and quack doctors may try, I can't see anything wrong with rewarding the companies that developed and are manufacturing this vaccine. Throwing their stock prices or financial health into the mix is what's known as a red herring.
