Vaccines Immune System Macrophages – eaters that leave antigens Antibodies – Attack antigens T-lymphocytes – attack infected cells NK cells – natural killer

Vaccines Innate Adaptive Nonspecific 1st Defense Antigen activated Macrophages T and NK cells Adaptive Specific 2nd Defense Army of Immune cells Memory cells B cells - antibodies T cells

Vaccines

Vaccines

Vaccines How Vaccines Work Imitates infection – does not cause it Produces T- lymphocytes and antibodies Body as Memory cells for future use

Vaccines

Vaccines Types of Vaccines Live, attenuated – weakened versions of virus Inactivated – inactivated version of virus Toxoid – prevent diseases associated with toxins/bacteria (Tetanus) Subunit – only contain antigens not whole virus/bacteria (pertussis) Conjugate – fight bacteria with outer sugar coating (Hib influenza)

Vaccines Many vaccines require multiple doses First dose – not enough immunity (inactivated) Toxid immunity wears off (subunit) More than one dose gives best immune response Flu virus evolves

Vaccines Vaccine Side effects Mild side effects are the most common (Redness/Itchy) Life threatening ones are rare Talk with your doctor on family history Immune diseases Allergies Any history of harmful side effects

Vaccines What if we Stopped Vaccinating?

Vaccines What if we Continue Vaccinating?

Vaccines Vaccine Statistics Disease rates are LOW in the US due to vaccination 15,000 Americans died of diptheria in 1921 Rubella killed 2,000 babies and caused 11,000 miscarriages in 1964-65 Most doctors never see a case of the measles Polio and Smallpox eradicated

Vaccines Anti vaxxers - DANGEROUS Vaccines DO NOT cause autism Genetic ties to autism 1.2 million children studied No link to vaccines Vaccines are safer than suffering deadly diseases Vaccine components are SAFE Unvaccinated people risk lives of Others Immunosuppressed Babies Elderly

Vaccines Vaccines BOOST immunity Diseases eradicated because of them Mild symptoms Better than suffering the disease Protects the population Does not cause autism Multiple doses give best response VACCINATE YOUR CHILDREN!
