2. 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
Vaccines can be made from viruses
Gene therapy
Cure cancer
Nikita Reveka

4. 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

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

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

7. 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

8. 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

9. 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

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

11. 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

12. 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

13. 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

14. 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

15. 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

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

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

18. 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

19. 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

20. ABC's What word in Latin means virus? a. dog b. poison
c. Poison or slimy liquid
d. bugs
Nikita Reveka

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

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

23. 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

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

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

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