The immune system is a complex network in the body that aims to prevent invasion from microorganisms. The immune system also works to destroy any microorganisms that manage to get into the body. There are many factors which influence how well our immune system defends our bodies against foreign microorganisms. Genes play a large role in the development of our immune system and what kinds of antibodies we carry.
Age is also a factor in the strength of the immune system.
Generally, infants and small children have weaker immune systems. That's why it's important to get your children immunized at the proper times.

The information includes a Schedule for Children , an Immunization Facts Sheet and what you need to know about Vaccine Safety .
