Aim: How can a vaccine help prevent a viral infection but not a bacterial infection?
Agenda
1. Do Now
2. Activity 1 - Virus Brain Pop
3. Activity 2 - Vaccine Brainpop
4. Check for Understanding
5. Activity 3 - Discussion Questions
6. Activity 4 - HPV

4. Why is this important?
In your lifetime you will be told to get vaccines through an injection. It is important to understand why we are putting these things into our body.

5. Activity 1 – Brain Pop – Viruses
Directions: Watch the video silently. Answer questions 1-4 based on the Brain Pop video. Be ready to share out your answers.

6. Activity 1 - Brain Pop Questions
1. What is a virus?
2. What does it need in order to reproduce?
3. How does the virus use the cell?
4. What are some examples of viruses?

7. Activity 2 - Brainpop - Viruses
Directions: Watch the video silently. Answer the questions based on the Brain Pop video. Be ready to share out your answers.

8. Activity 2 - Brainpop - Vaccines
1. What are vaccines used for?
2. How do antibodies and white blood cells fight pathogens?
3. Why can you only get the chicken box once?
4. What is in a vaccine?
5. How do vaccines work?
6. Why do you usually not get sick from a vaccine?

9. Check for Understanding
1. It is recommended that people at risk for serious flu complications be vaccinated so that their bodies will produce
antigens to fight the flu virus
antibodies against the flu virus
toxins to fight the infection caused by the flu virus
antibiotics to reduce symptoms caused by the flu virus
2. When a new viral infection appears in a population, scientists usually try to develop a vaccine against the virus. Which substances would most likely be contained in the new vaccine?
live bacteria that ingest viruses
white blood cells from an infected individual
weakened viruses associated with the infection
a variety of microbes that will attack the virus

10. Check For Understanding
If you got 0 or 1 correct, use the powerpoint on the class website to assist with the discussion questions.

11. Discussion Questions
1. Explain the difference between bacterial infections and viral infections
Your answer should include: antibiotics, vaccines, alive, host cell
2. Why can’t a viral disease be “cured” but bacterial diseases can?
3. Why is it that for certain viruses, you only have to get the vaccine once and your body will know how to fight off this disease and in cases such as the flu you have to get the flu shot every year?
4. Based on your knowledge of the immune system, do you think viruses or bacteria are more dangerous to your ability to stay alive? Why?

12. Activity 4 - HPV
Directions: Using the transcript from the video and the interactive website, make an argument on HPV. Your answer should include: A claim, reasons, evidence from the transcript or website, counter-claim, conclusion sentence.
Should states require mandatory HPV vaccines for students at public schools?

16. Immune System
When first exposed to disease, organisms make specific antibodies to mark the foreign invaders so the white blood cells know what to destroy.
If exposed to the same pathogen again, the immune system has a memory and can quickly make similar antibodies that will match the SAME antigens as the sickness from the previous time.
REMEMBER: since Antigens and Antibodies are proteins that specific shape that match. SHAPE DETERMINES FUNCTION

17. Illness and Germs
Pathogens is the term that refers to all germs and microbes that can cause illness in an organism?

18. Bacteria Bacteria are single-celled organisms.
They are alive because they can carry out the characteristics of life without needing the help for another organism

19. Characteristics of Life
Repair injury
Reproduce
Communicate
Digestion/Excretion

20. Viruses Viruses are non-cellular (not a cell)
They are dead because they cannot performs] the characteristics of life without having a host.
The infects to cause illness and death.

21. Cures and Treatment
Diseases caused by a bacteria can be cured because the bacteria can be killed.
Doctors inject a person with antibiotics to kill the bacteria
Viruses cannot be killed because they are NOT alive so there is NO cured for them
Vaccines can PREVENT viruses from infecting organisms

23. Vaccines
Vaccinations use dead or weakened microbes (virus) to stimulate the first production of antibodies
They are not as strong as the disease so the person does not get sick
Helps organisms build a memory of antibodies.

24. Vaccine Process A dead or weaken virus is injected into an organism
The immune systems recognizes the virus and synthesizes antibodies
The immune system makes a memory of the virus so when the real virus (not a dead or weak one) comes it can use the antibodies to stop it immediately.
