Two things such as clean drinking water and availability of vaccine have highly positive impact on quality of life. Vaccination are given to prevent and make body strong against a particular infection such as:
- Polio vaccine to prevent against polio.
- Flu vaccine to prevent against Flu
- Hepatitis B vaccine for prevent against Hepatitis.
- Pneumococcal vaccine is for prevention of pneumonia and so on.
Nature has provided immune system in our body to fight against infection and these are in shape T and B cells. Our immune system becomes stronger and active when it is combating infection or is in disease condition.
History of development of Vaccination
The term vaccine was first used by a British doctor Edward Jenner in year 1796. The term vaccine was derived from Latin word “vacca” which means cow. This word was used by him because the virus mainly effecting cow in shape of “cowpox”. He also noted that people affected by Cowpox don’t have small pox. He decided to do an experiment in the light of his above mentioned observation on human being. He selected a young boy for the experiment, by giving him cowpox virus and protecting him from smallpox. He extracted and scratched liquid from the cowpox source and given in to human body. The same method was observed in small pox cases. The difficulties were observed initially with this method / techniques of inoculation and were further refined with the time, experience and research.
Experiment to develop immunity in human
The Dr. Edward Jenner in light of his observation, he did experiment on the boy by injecting cowpox in the same way as people tried to give smallpox. After six weeks, he scratched smallpox into the boy’s skin. His observation and monitoring showed, the boy did not get sick from smallpox. In this way the same boy was the first person ever to receive vaccination.
Vaccine development path
It took nearly hundred years to develop another vaccine beside small pox was in 1879 that is cholera vaccine. At the current level there are now 28 vaccines developed to prevent and guard against various diseases.
