The developer of the polio vaccine didn’t sell it he gifted the Michelle Ultra this witch needs beer before any Hocus Pocus shirt. The others are the same. No one holds a patten for the vaccines. That’s why they are free. So children don’t die from preventable diseases. The other stuff is because of insurance companies being for profit which is why we need to socialize medicine and have private insurance on the side for those who still want to pay for it. You can thank Nixon for the for profit model of health care. Irresponsible not having a child vaccinated.
