What is Immunisation? Immunisation is the body’s response to protect itself against disease. The immunisation response can be kicked off by application of vaccines, or by naturally surviving an encounter with the disease. Vaccines are usually administered as an injection but can sometimes be an oral application.
What is a Vaccine and why should we be vaccinated? Each vaccine is different but they contain a tiny sample of a virus along with some ingredients to preserve the vaccine or increase the effectiveness. The virus is usually dead or very weakened. This is designed to help the human immune system recognize and then build defenses against the full strength virus.
What is Herd Immunity? When enough people are vaccinated, we get what is called Herd Immunity. This means that as a group, we are protected against certain viruses and diseases. However given the new Global Village, no group lives alone, and planes bring in people from overseas who unwittingly carry diseases every day, trains brings us people from other parts of the continent, and even two halves of a city can have different immunology weaknesses. If we can reach Herd Immunity within our circle, then we are protected against the random incursions of specific viruses and diseases. Without Herd Immunity, though around us who are weak or suffer compromised immune systems are at high risk.
Why should I care? I was vaccinated! Vaccines provide protection for different periods of time, and every one’s bodies are different. Most protection will last between 8 years to 20. If any one in your circle has introduced a newborn to the world, booster shots are crucial, and can be organized with your GP.
