Detailed explanation-1: -The vaccine is made from a virus called vaccinia, which is a poxvirus similar to smallpox, but less harmful. The smallpox vaccine contains live vaccinia virus, not a killed or weakened virus like many other vaccines.
Detailed explanation-2: -Dr Edward Jenner created the world’s first successful vaccine. He found out that people infected with cowpox were immune to smallpox. In May 1796, English physician Edward Jenner expands on this discovery and inoculates 8-year-old James Phipps with matter collected from a cowpox sore on the hand of a milkmaid.
Detailed explanation-3: -Before smallpox was eradicated, it was a serious infectious disease caused by the variola virus. It was contagious-meaning, it spread from one person to another.
