Vaccination is a simple, safe and effective way to protect people against harmful diseases. It uses our body's natural defenses to build resistance to specific infections and makes out immune system stronger.
Nearly everyone can get vaccinated. However, because of some medical conditions, some people should not get certain vaccines, or should wait before getting them. These conditions can include: Chronic illnesses or treatments (like chemotherapy) that affect the immune system; Severe and life-threatening allergies to vaccine ingredients, which are very rare; If you have severe illness and a high fever on the day of vaccination.
Vaccines reduce risks of getting a disease by working with your body’s natural defenses to build protection. When you get a vaccine, your immune system responds. It: Recognizes the invading germ, such as the virus or bacteria. Produces antibodies. Antibodies are proteins produced naturally by the immune system to fight disease. Remembers the disease and how to fight it. If you are then exposed to the germ in the future, your immune system can quickly destroy it before you become unwell.
