Immunizations, also called vaccinations, are given to protect you from diseases. Each vaccine contains small amounts of a weakened disease organism or its products, which usually are given by injection. Your immune system develops antibodies to fight the disease, which then recognize and attack the organisms if you are exposed to them in the future. Sometimes an immunization does not completely prevent the disease, but it will significantly reduce its severity. Some immunizations are given only once, while others require several treatments over a period of time.

The standard immunization schedule begins at birth. Immunizations are spaced throughout the baby's first 18 months; some are repeated between the ages of 4 and 6. Very few immunizations are needed after this age - just those given yearly (such as a flu shot) or on a regular basis throughout adulthood (such as a tetanus shot). All immunizations should be kept up-to-date. Additional vaccinations may be needed when traveling to certain parts of the world.

Following is the current recommended childhood and adolescent immunization schedule.
