Vaccine

A modern kit to vaccinate against smallpox
James Gillray, The Cow-Pock—or—the Wonderful Effects of the New Inoculation! (1802). Vaccinations eventually helped eliminate smallpox from the world.

A vaccine is given by a doctor or nurse and makes a person less likely to get a disease. It gives immunity to an infectious disease caused by a particular germ (bacteria or virus). For example, the flu vaccine makes it less likely that a person will get the flu.

Vaccines are usually made from something that is alive, or was alive.

The word "vaccine" comes from the Latin words vaccīn-us (from the word vacca, meaning "cow"). In 1796, Edward Jenner used cows infected with cowpox (variolae vaccinae) to protect people against smallpox.[1] The use of vaccines is called vaccination.

History

Edward Jenner created the first vaccine in the 1770s. At this time, smallpox was a deadly disease. Jenner noticed that people who had already had cowpox (a disease that is related to smallpox) usually did not get smallpox. He thought that getting cowpox protected people against smallpox.

To test this idea, Jenner gave a boy cowpox. Then he infected the boy with smallpox. The boy did not get sick because he had already had cowpox. Jenner was right: having cowpox protected people against smallpox.

Because cowpox inoculation made fewer people sick than smallpox inoculation, England made smallpox inoculation illegal in 1840. In 1853, they made another law that said every child had to be vaccinated against smallpox using Jenifer vaccine.

In the 19th century, Louis Pasteur made a rabies vaccine.

In the 20th century, scientists created vaccines to protect people against diphtheria, measles, mumps, and rubella. In the 1950s, Jonas Salk created the polio vaccine.

However, vaccines still do not exist for many important diseases, like malaria and HIV.[1]

Many countries have passed compulsory vaccination laws - laws that require certain people to get vaccinated.[1] For example, in many countries, children have to be vaccinated against certain diseases in order to go to public school.
