The surgeons of America would develop an immune method in the body by exposing them to it they know its there and the body fights it better, is the right answer.
During the Revolutionary wars, a severe threat to the continental army came from a disease called Smallpox. George Washington was the general of the continental army. During the time when this disease attacked the army, the general of the army quarantined the soldiers who showed the earlier signs of the disease. but later on, surgeons founded a new remedy that would give the disease to fit patients so that they could be immune. The main risk in this process was that their immune system would not respond quick enough. And that they would not get the disease was one of the rewards of this immune system.
One very famous one was an improvised vaccination. What people did (I think I read somewhere that this practice was observed in the slaves) was open skin of healthy people and place some liquid from woulds of sick people inside of it during an epidemic (such as smallpox): this way the disease was more controlled.
It was risky (what if the person got seriously sick and died?) but it gave some hope of survival to those that would likely anyway get the disease. Especially soldiers, who were in big groups were susceptible to epidemics and it is believed that this way of vaccinating saved many lives.
A government's basic functions are providing leadership, maintaining order, providing public services, providing national security, providing economic security, and providing economic assistance.
As the earliest ancestors of Native Americans, they can be considered to be descended from the Paleo-Indians. They shared the use of fire and trained dogs with their Asian counterparts, but grazing animals, domesticated plants, and the wheel did not seem to be Old World innovations.
