Back to School Immunizations

Immunizations—or vaccines as they're also known—safely and effectively use a small amount of a weakened virus or bacterium to prevent infection by that very virus or bacterium.

When your child gets an immunization, he or she is injected with the weakened virus or bacterium that causes a particular disease. This triggers the body's immune response, causing it to produce antibodies to that particular ailment.

Then, if the child is ever exposed to the disease-causing germ, his or her immune system is prepared to fight the infection with the antibodies it has formed. A vaccine may not completely prevent the onset of a disease, but it will reduce its severity.

As a reminder, always consult your doctor for medical advice and treatment before starting any program.
