Childhood Immunization Part 1

Shots Hurt! Why Do We Give Them? Vaccines work! Vaccines are the MOST effective preventive measure that modern medicine has derived

A Brief Intro into the Biology of Vaccines Antigens are substances our bodies view as FOREIGN Our immune system recognizes FOREIGN antigens and mounts an immune response, in the form of ANTIBODIES to eliminate it. After the antigen has been eliminated the immune system retains a memory of that antigen: next time it appears the antibody response is faster and stronger!!

Germs are Antigenic The proteins and sugars on the walls of viruses and bacteria are FOREIGN Your body makes antibodies to fight them off

Theory of Vaccines Present the body with a germ antigen that can not produce disease Body will produce antibodies to the germ This will prevent disease if the body later encounters that germ, because the antibodies will fight off the germ before it has a chance to make you sick

Vaccine Types Live vaccines: attenuated, must reproduce to produce immune response Killed vaccines: pieces (sugars or proteins) of the germ wall, can not reproduce Conjugated vaccines: germ sugar attached to a protein to enhance immune response

Immunization Schedule for ages 0-6

Immunization schedule for ages 7-18 years

Summary of Immunization Strategies Total Eradication: Smallpox, Polio (possibly) Herd Effect: Childhood immunization programs Ring Approach: Immunize those individuals at risk due to potential exposure (meningitis) Selective Approach: Influenza
