Immunizations:
The "2004 Childhood Immunization Schedule" was published in
the January 16, 2004, issue of the Center for Disease Control's "Morbidity
and Mortality Weekly Report" (MMWR).
The new schedule has significant changes and new vaccine recommendations
that were not on the 2003 schedule.

How do vaccines work?
As a parent, your children's health and safety are always on your mind. You
know the value of safeguards like child-proof door latches, regular tooth
brushing and pool-side security alarms. They are meant to prevent everything
from minor illnesses to tragic death. Baby shots do the same thing--they
work to safeguard your child from illness and death caused by infectious
diseases.
Vaccines help your baby's body prepare to fight deadly diseases.
Here's how . . . it takes practice
-
First: Vaccine is given by shot or as a liquid by
mouth--vaccines contain a weak or dead disease germ.
-
Next: The body makes antibodies to fight the weak or dead
germs in the vaccine.
-
Then: These antibodies practice on the weak germs so when
the real, strong disease germs--which can be lurking all around--invade
the child's body, the antibodies will know how to destroy them and the
child will not become ill.
-
Finally: Protective antibodies stay on guard in the
child's body to safeguard it from the real disease germs.
Antibodies fight infectious diseases and usually stay in
your system--even after the disease is gone--to protect you from getting
sick again. This is called immunity.
Newborn babies are immune to many diseases because they have antibodies they
got from their mothers. But this immunity does not last. It wears off in the
first year of life. Fortunately, we can keep children immune to many
diseases, even after they lose their mothers' antibodies. We do this by
vaccinating them against those diseases.
Vaccines give your baby's immune system the chance to practice and make
protective antibodies before real germs invade. If left totally to chance,
your baby's first exposure to a disease may be from a germ too strong for
your baby to fight. That's why before parents had vaccines for their
children, many children died from whooping cough, measles, diphtheria and
other diseases. Those same germs exist today, but today's babies are
protected by vaccines.
