Vaccines are made by taking viruses or bacteria and weakening them so that they can’t reproduce (or replicate) themselves very well or so that they can’t replicate at all. Children given vaccines are exposed to enough of the virus or bacteria to develop immunity, but not enough to make them sick.

What’s inside a vaccine?

Each vaccine contains a small amount of the disease germ (virus or bacteria) or parts of the germ. Examples are the measles virus, pertussis (whooping cough) bacteria, and tetanus toxoid. Vaccines do not cause disease because the germs are either dead or weakened and the toxoids are inactive.

Where does mumps virus come from?

Mumps is caused by a virus that spreads easily from person to person through infected saliva.
