Vaccines reduce the risks of getting a disease by working with your body’s natural defences to build protection.
When you get a vaccine, your immune system responds.
According to the World Health Organisation, there are vaccines to prevent more than 20 life-threatening diseases, helping people of all ages live longer, healthier lives.
Immunisation, they said, currently prevents 3.5-5 million deaths every year from diseases like diphtheria, tetanus, pertussis, influenza and measles.
Immunization is a key component of primary health care and an indisputable human right.
