Immunisation then protects your child against harmful infections. This is done by enabling your child to be able to fight the bugs if they do come into contact with the disease.

To explain the immune response simply, a vaccine artificially stimulates the body’s immune response. The body then stores and remembers how to kill the bugs if it comes into contact with the disease in the future.

Immunisation also helps to protect other children from getting serious diseases. The more children are immunized means that the disease can not spread from one child to another. As the disease can not live without its host if
Enough children are immunised, the disease may well die out altogether.

Indeed, this is what happened with the disease smallpox. Many countries vaccinated their populations against the disease and smallpox has almost completely been irradiated.

Hopefully then, many diseases for which your child has currently been vaccinated against may be eradicated in the future, but this depends on parents continuing to have their children vaccinated.
