Vaccines

Immunization is a global success story in terms of health and development, saving millions of lives each year. Vaccines reduce the risk of contracting a disease by enhancing your body's natural defenses. Your immune system reacts when you receive a vaccine. We now have vaccines to prevent over 20 potentially fatal diseases, allowing people of all ages to live longer, healthier lives. Immunization currently saves the lives of 2-3 million people each year from diseases such as diphtheria, tetanus, pertussis, influenza, and measles. Immunization is an essential component of primary health care and an inalienable human right. It's also one of the best health investments you can make with your money. Vaccines are also important in the prevention and control of infectious disease outbreaks.
