Overview Ways viruses can benefit your life, how some viruses are harmful, spreading of disease and prevention of viruses Influenza, the flu and how it works, how vaccines work. Attenuated Vaccines, Weakened form of the germ, prevents viruses from getting you sick Inactivated Vaccines, A dead version of the Germ, protects from the flu Subunit Vaccines, used when one part of the virus is causing the disease Toxoid Vaccines, Made from toxins

Ways Viruses Can be Beneficial in your Life                                                                                                                                                                              Ways Viruses Can be Beneficial in your Life Vaccines can be made from viruses Gene therapy Cure cancer Nikita Reveka

Ways viruses harm our lives Viruses affect our body by attacking our cells You can get very sick It could also attack your nervous system  You can get hospitalized  Nikita Reveka

Spreading of diseases Coughing/sneezing Touching or shaking hands Sexual contact Exchanges of saliva Nikita Reveka

Prevention of viruses Wash your hands Get a vaccine Stay home if your sick Use single use- tissues Nikita Reveka

Influenza Rian Granito Get shot every year evolves and mutates quickly  antibody change as time goes on Everyone over 6 months should get flu shot Rian Granito

Influenza (cont.) Rian Granito Antibodies protect you from virus Last year's vaccine won't work for this year's virus structure changes shape and structure Children under five have higher risk of getting flu Rian Granito

How Vaccines Work Rian Granito antibodies protect you from virus fight against the disease Lymphocytes create antibodies Antibodies attack antigen and prevent infection Rian Granito

How Vaccines Work (cont.) several days for antibody reaction Provide immunity weakened antigens fight infection Immune system fights virus Rian Granito

Attenuated Vaccines Weakened form of the germ Created by reducing the virulence of a pathogen, but still keeping it alive Creates a long lasting immune response 1 or 2 doses of the vaccine gives you a lifetime of protection from the germ Joseph Martino

Attenuated Vaccines Prevents viruses from getting you sick  Needs to be kept cool Doesn't travel well Protect you from are small pox, chicken pox, and shingles  Joseph Martino

Inactivated Vaccines Killed version of the germ May need several doses over time Does not provide immunity  Not as strong as live vaccines  Joseph Martino

Inactivated Vaccines Protects you from sickness Takes about 2 weeks to protect you from sickness Typically for people with immunodeficiency  Protects you from the Flu, Hepatitis A, and Rabies Joseph Martino

Subunit vaccines Relatively easy to produce Subunit vaccines are used when one part of the Virus is causing the disease  This cannot cause the disease They are difficult to make Nick Wursta

Subunit Vaccines Use genetic engineering techniques to produce Subunit vaccines can contain from 1-20 antigens An antigen is the protein responsible for the disease Examples: Hepatitis B, Gardasil Nick Wursta

Toxoid Vaccines Vaccine made from toxins or poison Harmless Starts an immune response against the toxin Stable and long lasting  Nick Wursta

Toxoid Vaccines Exotoxins inactivated by heat or chemicals Used when bacterial toxins are cause of illness Used to become immune to toxin Examples: Tetanus, Diphtheria Nick Wursta

ABC's Vaccines can be used to prevent viral infection by: a. getting an immune response from the host b. killing the virus c. Make the virus smaller d. Getting the virus out of your system Nikita Reveka

ABC's ?: What system fights back the flu? a.: skeletal b.: nervous c.: immune d.: cardiovascular Rian Granito

ABC's ?: what cells create antibodies? a.: lysosomes b.: lymphocytes c.: lipids d.: lactose Rian Granito

ABC's ?: How many vaccines can give you a lifetime protection of a germ?  a.: 1 or 2 b. 3 or 4 c. 5 or 6 d. 7 or 8 Joseph Martino

ABC's ?: What virus won't protect you with vaccines? a.: chicken pox b.: shingles c.: Klinefelter d.: small pox Joseph Martino

ABC's How many Antigens can a subunit Vaccine Contain? a. 1-20 d. 41-50 Nick Wursta

ABC's What are exotoxins inactivated by? a. Snow b. Water c. Heat or Chemicals d. Rocks Nick Wursta
