Why are children/ infants given vaccination?

Question

Filo · Accepted Answer

When a disease-carrying microbe enters our body, the body produces antibodies to fight the invader. The body also remembers how to fight the microbe if it enters again. So, if dead or weakened microbes are introduced into a healthy body, the body fights and kills them by producing suitable antibodies. The antibodies remain in the body and we are protected from the disease-causing microbes. This is how a vaccine works. Several diseases, including cholera, tuberculosis, smallpox and hepatitis can be prevented by vaccination. In your childhood, you must have been given injections to protect yourself against several diseases. It is essential to protect all children against these diseases. Necessary vaccines are available in the nearby hospitals. You might have seen the advertisement on T.V. and newspapers regarding protection of children against polio under Pulse Polio Program. Polio drops given to children are actually a vaccine. A worldwide campaign against smallpox has finally led to its eradication from most parts of the world. These days vaccines are made on a large scale from microorganisms to protect humans and other animals from several diseases.
