Know the facts first. Immunizations, or vaccines, can help prevent many diseases in both children and adults.
Immunizations work by helping the body produce antibodies against the disease.
These antibodies work to fight infections. Recommendations about when to have your child immunized change occassionally. Some shots are given earlier to children where diseases are more common. Your child's pediatrician will give you a card keeping track of what immunizations have been given and which ones are due when. Your local health unit will give the immuniations for a nominal fee or even free, if you cannot afford them, and also give you a card to keep track of the immunizations.
