Elsevier Inc. items and derived items © 2010 by Saunders, an imprint of Elsevier Inc.2 * Purpose is to protect against infectious diseases. * Most effective method is to create a highly immune population. * Universal vaccine is the goal. * Vaccines carry risk – but risks of disease are much greater.

Elsevier Inc. items and derived items © 2010 by Saunders, an imprint of Elsevier Inc.3 * Definitions Vaccine Killed vaccines versus live vaccines Toxoid Vaccination Immunization; active versus passive Specific immune globulins

Elsevier Inc. items and derived items © 2010 by Saunders, an imprint of Elsevier Inc.4 * A vaccine is a biological preparation that improves immunity to a particular disease * Contains whole or fractionated microorganisms * Once administered, the recipient’s immune system begins making antibodies against the microbe * Most of what we will be talking about will be vaccines

Elsevier Inc. items and derived items © 2010 by Saunders, an imprint of Elsevier Inc.5 Two major classes of vaccines: * Killed – whole, killed microbes or microbial components * Live (attenuated) – composed of live viruses weakened in force or effect (diluted) rendered avirulent Why should caution be used with live vaccines in immunocompromised recipients?

Elsevier Inc. items and derived items © 2010 by Saunders, an imprint of Elsevier Inc.6 Immunocompromised children are at special risk from live vaccines  Congenital immunodeficiency  HIV infection  Leukemia  Lymphoma  Generalized malignancy  Therapy with radiation  Cytotoxic anticancer drugs  High-dose glucocorticoids

Elsevier Inc. items and derived items © 2010 by Saunders, an imprint of Elsevier Inc.7 * A bacterial toxin that has been changed to a non-toxic form * Once administered, the recipient’s immune system begins making antitoxins (antibodies directed against the natural bacterial toxin) * Antitoxins protect the recipient against injury from toxins, but do not kill the bacteria that produced it * e.g. Tetanus and diptheria

Elsevier Inc. items and derived items © 2010 by Saunders, an imprint of Elsevier Inc.8 The administration of any vaccine or toxoid

Elsevier Inc. items and derived items © 2010 by Saunders, an imprint of Elsevier Inc.9 Active * Develops in response to infection or to administration of a vaccine or toxoid * Endogenous production of antibodies * Takes weeks or months to develop but is long lasting Passive * Is obtained by giving a patient preformed antibodies (immunoglobulin's) * Provides immediate protection * Only lasts as long as the antibodies remain in the body 9

She comes to the nurse’s office complaining that she has a headache, she doesn’t feel well, and she has a rash on her belly that is bothering her. After you and the school nurse make your assessments, you call Jane’s mother and ask her to come pick up Jane because you suspect that she has chickenpox.

Elsevier Inc. items and derived items © 2010 by Saunders, an imprint of Elsevier Inc Jane’s mother arrives at the school. She says, “You’re wrong. Jane can’t have chickenpox. I made sure she got the vaccine so I wouldn’t have to go through chickenpox with her.” What is your best response? 2. Jane’s mother continues, “I have a 1-month-old baby at home, and I don’t think I’ll bother having him vaccinated for chickenpox. What good did it do Jane?” What is your best response?
