A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease.

A vaccine is a type of medicine that trains the body’s immune system so that it can fight a disease it has not come into contact with before. Vaccines are designed to prevent disease, rather than treat a disease once you have caught it.

Vaccines that contain weak and dead germs such as viruses or bacteria train the immune system to make antibodies just as they do when exposed to disease. Vaccines will not harm and cause disease to a person. The vaccine is given by injection into the body but can also be administered by mouth or sprayed into the nose.

Vaccines are produced from part or all of the structure of a virus or bacteria that has been killed or weakened or from a subunit protein in the virus.

Antigens in vaccines work to stimulate the body's immune system.

Vaccines help the immune system identify certain germs so that the immune system is well prepared to be attacked by real germs.


The act of introducing a vaccine into the body to produce immunity to a specific disease.

Vaccination is a safe, easy and effective way to protect people from any dangerous diseases before they come in contact with each other.

Vaccination will use the body’s natural defenses, making the immune system stronger and to build resistance to certain infections.


1. You are given a small amount of a harmless form of a disease

2. Then your body makes antibodies to fight it off

3. Then if you encounter the disease again, your body already has the antibodies, so you don't get sick.
