Immunizations and Children

This site is a resource for those seeking information regarding immunizations for children in British Columbia. Throughout this website is information regarding the recommended immunizations for children residing in British Columbia, research summarizing the controversy of immunizations, information regarding immunization safety concerns for your child and tips for proper immunization record keeping and documentation.

The World Health Organization summarizes that immunizations are designed to make a person resistant to an infectious disease by the administration of a vaccine. Vaccines cause the immune system to become activated against the infection or disease later in life (World Health Organization, 2008).

"Immunization is a proven tool for controlling and eliminating life-threatening infectious diseases and is estimated to avert over 2 million deaths each year. It is one of the most cost-effective health investments, with proven strategies that make it accessible to even the most hard-to-reach and vulnerable populations. It has clearly defined target groups; it can be delivered effectively through outreach activities; and vaccination does not require any major lifestyle change" (WHO, 2008).

The BC Health Guide Website (2008) states:

"Immunizations are important for people of all ages. They help your immune system recognize and quickly attack organisms that could otherwise cause serious or even fatal disease. Some immunizations are given in a single shot or oral dose, while others require several doses over a period of time. In BC, immunizations are given by public health nurses in your local public health unit or by a physician. Some workplaces also have occupational health nurses who can give immunizations according to requirements and recommendations of employers".

A vaccine works by producing one of two types of immunity. Active immunity takes place when a vaccine causes the immune system to produce antibodies against the disease. In this case, the body responds as though the body has been infected with a small amount of the disease (ImmunizeBC, 2008).

Passive immunity is a second type of immunization. In this type of immunization, antibodies are given to the individual rather than having the body producing them. Immunizations for Measles, Mumps and Rubella are examples of passive immunization and are provided by the mother during gestation. However, passive immunity only lasts for a short period of time, therefore the MMR (Measles, Mumps, Rubella) is given to newborns after a year of life (ImmunizeBC, 2008).

Along with the immunization, a dose of the vaccine may include:

A suspension fluid to transmit the vaccine into the body
Preservatives to safely store the vaccine until it can be administered
An adjutant to help improve the normal body immune response
