Timeline of vaccines


This is a timeline of the development of prophylactic vaccines. Early vaccines may so the first year of development or testing but later years usually show the year the vaccine finished trials and came on the market. Although vaccines exist for these human diseases, only smallpox has been eliminated worldwide and these diseases continue to causes ten's of millions of deaths each year. Polio and measles are the current targets of worldwide eradication campaigns.

NationMaster - Encyclopedia: Timeline of vaccines (402 words)
Vaccines have contributed to the eradication of smallpox, one of the most contagious and deadly diseases known to man. Other diseases such as rubella, polio, measles, mumps, chickenpox, and typhoid are nowhere near as common as they were just a hundred years ago.
A vaccine (named after vaccinia, the infectious agent of cowpox, which, when innoculated, provides protection against smallpox) is used to prepare a human or animal's immune system to defend the body against a specific pathogen, usually a bacterium, a virus or a toxin.
Dissenters falsely suggest that modern vaccines might result in outbreaks of smallpox (in fact, they contain no smallpox virus: they contain live vaccinia virus), and suggest that infections in the past originated (as in the small vaccinia outbreak in England in 1961), spread in greater proportion, and/or were more lethal amongst the vaccinated.

Vaccination is the process of administering pathogens that cant reproduce (due to being weakened or dead) to a healthy person or animal, with the intent of conferring immunity against a targeted form of a related disease agent.
Vaccination Vaccination is the process of administering pathogens that cant reproduce (due to being weakened or dead) to a healthy person or animal, with the intent of conferring immunity against a targeted form of a related disease agent.
Vaccines that provide active immunization are made in a variety of ways, depending on the type of disease and the organism that causes it.
