What is immunisation?Immunisation is using a vaccine to protect people from getting a disease. Vaccines contain either small parts of the viruses or bacteria which cause the disease, or very small amounts of the chemicals these viruses produce. The vaccine ingredients have been treated so that they do not cause disease. When we are given a vaccine, either by injection or by mouth (as with polio vaccine), our bodies are stimulated to make substances called antibodies which defend us against future infections. Our bodies make special cells which can remember and recognise infections, so if we meet the disease later on, the body’s defences (the antibodies) fight, and prevent the infection from getting a hold. The usual programme of infant vaccinations in the UK is spread out over several months, though most of the vaccinations are given in the first four months. It’s important to complete the course of vaccinations for maximum protection. Keep a record of which vaccinations your child has, and when. |
