Your doctor can help you stay healthy by offering you appropriate vaccinations to reduce your risk of getting infected with diseases that are potentially life-threatening. Many vaccines are given in childhood, but adults can also be vaccinated to prevent illness such as tetanus and influenza.

Your body can become immune to bacteria, viruses and other germs by getting a disease – this is called natural immunity. Immunity can also be developed through vaccines – vaccine-induced immunity. Vaccines work by stimulating an immune response without causing disease. Several doses of a vaccine may be needed for a full immune response and it should be noted that vaccines are not free of possible side effects, which often include swelling at the injection site or a mild fever.

Vaccines are the first line of defence against diseases such as polio, measles, tetanus, mumps, rubella, influenza and diphtheria. Were it not for the widespread use of vaccines, a far greater number of deaths would have occurred in childhood, and a great many more people would be living with the chronic and crippling after-effects of disease.

Despite the proven benefits of vaccines there is public concern about their safety and possible side effects, but vaccination continues to be strongly recommended by doctors because gaining natural immunity involves considerable risk.

Vaccination is generally considered by health experts to be the right thing to do as it protects you as well as others. If you have any concerns about vaccinations for which you or your child are eligible, however, it is important to discuss them with your doctor before you come to an informed decision.

Whatever you decide, remember that the overwhelming majority of evidence and research suggests that vaccinations save lives.
