Presentation Transcript

Slide1

VaccinationsSlide2

Purpose

Expose body to antigens so that memory cells are made without causing

disease– stimulates acquired immunity without disease pathologySlide3
Slide4

Types of Vaccines

Live

Unattenuated

– unaltered pathogen given RareEx. Small pox vaccine – use live, unaltered cow pox vaccine

Slide6

Live Attenuated – altered/weakened to remove virulence

Should not be given to

immunocompromised

individualsMMR, nasal flu, chicken pox, oral polio, yellow fever, rabiesLess need for boosters than killed vaccinesCan be administered in a variety of waysSlide7
Slide8

Killed/Inactivated – use chemicals or heat to kill and are not infectious

Polio shot, flu shot, cholera, pertussis (whooping cough)

Usually require booster shots

Safe to give immunocompromised individualsSlide9
Slide10

Toxoids – stimulates body to produce antibodies to toxins produced by bacteria rather than the bacteria itself

Diptheria

, tetanusSlide11
Slide12

Risks

In live vaccines, there is a low risk that the vaccine will cause the disease (more likely in

immunocompromised

individuals)Occasionally a vaccine can overstimulate the immune systemSome vaccines are made with ingredients that may cause allergic reactions (egg is most common)Slide13

Herd Immunity

I

f

most of the people in a community have been immunized and are protected from an infectious agent, the chance of a susceptible (i.e. unimmunized) individual contacting an infected individual is so low that the susceptible person is not likely to become infected.Slide14
