“Finally, profit margins are incredibly low for vaccine manufacturers, who are basically distributing the vaccine out of their desire to be good corporate citizens. They would make a lot more money by investing their resources elsewhere.”
I find that assertion very difficult to believe. Any alleged lower profit margin must certainly be made up for by the sheer volume of vaccines they sell.
As this is a capitalist society and these are public corporations who are accountable to their share-holders, I have no doubt the vaccine manufacturers are in this business for money, not kindness, and therefore must be subject to the same scrutiny as any health-care business should be, and not be automatically trusted due to their alleged goodwill.
Essentially, everyone relies on governmental regulatory agencies to ensure these vaccines are in fact, safe and appropriate.
May Hashem watch over and protect His children.
