Smallpox vaccine, the first successful vaccine to be developed, was introduced by Edward Jenner in 1796. He followed up his observation that milkmaids who had previously caught cowpox did not later catch smallpox by showing that inoculated cowpox protected against inoculated smallpox.
Rubella vaccine is a vaccine used to prevent rubella. Effectiveness begins about two weeks after a single dose and around 95% of people become immune.Countries with high rates of immunization no longer see cases of rubella or congenital rubella syndrome. When there is a low level of childhood immunization in a population it is possible for rates of congenital rubella to increase as more women make it to child bearing age without either vaccination or exposure to the disease.Therefore, it is important for more than 80% of people to be vaccinated.

When vaccines are injected it is called vaccination.

For the first time, a scientist named Edward Jenner discovered vaccination by inventing vaccine for small pox disease.
