Vaccination. The principle behind which vaccines work is that it contain germs that are weak or dead thus they dont make a person sick. Having these germs in our system triggers our immune system

Extracts from this document...

Introduction

When foreign substances (antigens) such as germs enter out body, our immune system recognizes them. In return they "produce the right antibody to fight the antigens." (Kelly) Vaccination is "a disease-causing agent that is given to a person in a killed or weakened form (or in the form of proteins genetically engineered to look like a disease-causing agent), in order to stimulate the production of antibodies to fight off the disease."(Gazis-Sax) It protects us from specific diseases and "boosts [our] body's own defense system" (What is vaccination...) which is also known as the immune system. The principle behind which vaccines work is that it contain germs that are weak or dead thus they don't make a person sick. ...read more.

Middle

These cells present in vaccines "do not respond immediately when [they] first encounter an antigen" (Memory Cell) but rather they initiate a secondary response when the same antigen attacks for the second time. This way the immune system is more effective and more rapid. Primary immune response is our 1st line of defense when our immune systems produces antibodies by b-lymphotyes cloning themselves through meiosis and are specific to the antigen in our bloodstream. Vaccines aim to produce a weakened strand of a certain antigen into our body to create primary immune defense. The other way of obtaining antibodies is through artificial means known as the passive immunity. ...read more.

Conclusion

There are various infectious diseases that have been eliminated in various countries through the process of routinely vaccinating the children. For instance, in "the 1960s, many people witnessed first-hand, the terrible effects of rubella, commonly known as German measles. During an epidemic between 1964 and 1965, about 20,000 infants were born with deafness, blindness, heart disease, mental retardation, and other birth defects because the rubella virus infected their pregnant mothers. Today, thanks to nearly universal use of an effective vaccine, the rubella virus poses virtually no threat to the children of expectant mothers." (Satcher) Furthermore, vaccines not only save lives by preventing the infectious disease agents, they also save money. There are health organizations that help subsidize the cost of vaccines and in addition getting a vaccine is far less cheaper than treating the treatment itself if it occurs. ...read more.
