Vaccine

pock, a disease which has been found to affect the cow on the teat or udder, which arises in pustules resembling small pox; it has been found that this is a perfect preventive of small pox and is now growing into use against prejudice among all civilized nations. All armies should undergo the vaccine inoculation, to prevent the ravages of small pox; one half of the American army that went against Quebec in 1775 was swept off by small pox.
