Long time ago, people was suffering from communicable infections and could not do something about it due to limitations. Many people die because of infectious diseases back then. Luckily, there were several scientists who dedicated themselves to search for the perfect prevention. Greek observant realized that people who were not dying by smallpox did not get the same disease later on. This concept was the start of vaccination. Edward Jenner came out with the idea of the term “vaccine” that was derived from Variolae vaccinate while successfully try-out cowpox to prevent smallpox.
Vaccine is the preparation for your body to adapt to certain disease before it actually attacks your body. Vaccination is consisted of introduces your body to agent which is weakened or killed viruses or bacteria in very safe amount. After that, your immune system will try to identify the agent as foreigner. Because this agent is recognized as foreign agent, your immune system will destroy it and create antibody which remembers how to do if this agent enters your body again. It is basically allowing your body to learn how to recognize and attack particular disease microbe. There are four types of vaccine which are attenuated vaccine, inactivated vaccine, toxoid vaccine, and biosynthetic vaccine.
Attenuated or live virus vaccine which uses debilitated virus is widely practiced to encounter measles, mumps, rubella, and varicella or chickenpox. Inactivated vaccine which created from tiny pieces of virus or bacteria like its protein is used in the prevention of pertussis (whooping cough). Toxoid vaccine which is contained of microbe’s toxin makes people at prevented from the harmful effect of the infectious diseases such as diphtheria and tetanus. Lastly, the source of biosynthetic vaccine is made artificially in the lab that created to be identical to the virus or bacteria. This vaccine is used in Hepatitis B prevention.
World Health Organization (WHO) is battling infectious diseases since years ago. Preventing the vaccine-preventable diseases is as same as letting people to stay alive and productive. In 2012 at the 65th World Health Assembly, many of governments in the world were making pact to join Global Vaccine Action Plan (GVAP). GVAP is a project created to avoid millions of deaths comes from infectious diseases which have already vaccines to prevent them by 2020. This framework commits to make routine immunization stronger, eradicate polio as the first goal in vaccine-preventable diseases controlling, introduce noble vaccines, and encourage vaccines and technologies research and development.
