How does a vaccine work to prevent disease?
Asked by unknown
1 Answers
The diseases that vaccines prevent can be dangerous, or even deadly. Vaccines reduce the risk of infection by working with the body's natural defenses to help it safely develop immunity to disease. When germs, such as bacteria or viruses, invade the body, they attack and multiply.
Do vaccines weaken the immune system?
Asked by unknown
1 Answers
A healthy baby's immune system can accommodate multiple vaccinations. Also, vaccines do not make a child sick with the disease, and they do not weaken the immune system. Vaccines introduce a disabled antigen into the body so the immune system can produce antibodies against it and create immunity to the disease.
Why children need to be immunised?
Asked by unknown
1 Answers
First, immunisation prevents children from becoming ill with unpleasant and serious infectious diseases, which have a risk of complications and long-term effects. Until these diseases are eradicated, every child that is not immunised is at risk of complications if they catch the actual infectious disease itself.
