Immunizations For Children: What You Need To Know...

Immunizations are designed to protect against serious illnesses ranging from polio and tetanus to measles, mumps, and the seasonal flu. Many people consider them the most important part of well-child checkups.

How immunizations work
Immunizations are vaccines made from either weakened or killed versions of the bacteria or virus that cause a particular disease. When these altered viruses and bacteria are injected or taken orally, the immune system mounts an attack that stimulates the body to produce antibodies.
These antibodies remain active in the body, ready to fight off the actual illness if necessary. For example, if pertussis (whooping cough) breaks out in your area, an immunized child is much less likely to contract the disease than one who wasn't immunized. And if a child gets pertussis despite being immunized, the disease is usually much milder and less likely to result in serious complications.

2017 CDC immunization schedule
Every year, the Advisory Committee on Immunization Practices at the U.S. Centers for Disease Control (CDC) publishes a new schedule showing which vaccines are recommended and when to get them. This schedule is endorsed by the American Academy of Pediatrics and the American Academy of Family Physicians.
