The Gates Foundation has zero stocks in vaccine companies. Those aren’t money-making ventures; they’re gifts. If you look at their SEC filings (https://sec.report/Document/0001104659-20-062657/) you can see all their holdings. It’s Coca Cola, Apple, Walmart, etc.
They gift money to support causes they believe in. Andrew Carnegie built libraries. John D. Rockefeller supported universities and medical training. Bill Gates supports disease prevention (including vaccines, but also mosquito nets and other tools).
you’re a frickin fool.
