Panopto Lecture: The Immune System
1.
What are the two general parts of the vertebrate immune system? What is the
fundamental difference between them?
Innate immune system and acquired immune system. The acquired immune system learns
to recognize pathogens whereas the innate immune system provides immediate
preconfigured responses to sets of stimuli.
2.
What are the components of the innate immune system?
Immune sensing and innate immune cells.
3.
What are the components of the acquired immune system?
Macrophages, T-cells, and B-cells.
4.
What do memory cells do?
Why are they called memory cells?
Memory cells provide a fast and strong response to pathogens that they “remember”, which
is why they are called memory cells.
Panopto Lecture: Vaccine Development
1.
Explain the general principle of how vaccines work.
They expose the body to immunogens to active the acquired immune system and memory
cells provide protection.
2.
What are the different types of vaccines and how are they different?
Heterotypic: a pathogen of another animal that is harmless
Inactivated: virus that has been inactivated by heat, chemical, or radiated
Attenuated: active, but a less virulent or non-virulent strain
Toxoid: inactivated toxins, mostly microbial
Subunit: a fragment or part of the virus
3.
What are the different phases of clinical trials for vaccines?
Phase I: assess safety in healthy people, lowest effective dose, blind, control treatment with
placebo, and a sample size of 30+.
Phase II: builds on results from phase I, measures effects on a more diverse group of
people, tries different schedules. Sample size of several hundreds.
Phase III: continue to monitor toxicity, adverse effects, effectiveness to induce immunity in
natural settings. Sample size of 10,000-100,000
Phase IV: continued monitoring of adverse effects, long-term immunity.
Panopto Lecture: Covid-19 Vaccines
1.
What component of SARS-CoV-2 is contained in the new vaccines?
The spike protein.
2 of 2
2.
What is the vaccine ‘vehicle’ in the BioNTech/Pfizer and Moderna vaccines?
And in the Johnson & Johnson vaccine?
BioNTech/Pfizer and Moderna: mRNA of Sars-CoV2 spike protein in a lipid-nanoparticle
Johnson and Johnson: modified Adeno virus containing spike protein DNA.
3.
What are the advantages and disadvantages of each of the three vaccines?
A disadvantage of the BioNTech/Pfizer vaccine is that it must be stored at -70 degrees
Celsius. An advantage of the Moderna vaccine is that it can be stored in a regular fridge for
30 days or a freezer for 4 months. An advantage of the Johnson and Johnson vaccine is that
it can also be stored in a regular fridge because DNA is more stable than RNA.

Part A
Systemic lupus erythematosus (SLE), commonly referred to as just lupus, is an autoimmune disease. One method of diagnosis is to perform an antibody titer (measure of antibodiies) to assess if auto-antibodies are present. A patier
- has the antibody titer done, and zero antibodies are present. Does this indicate that the patient has lupus? Why or why not?
If there are not antibodies specific for lupus, the patient does not have the disease. Antibodies are produced in response to specific antigens and are used as a diagnostic tool for many diseases. Antibodies are only
produced once B cells are exposed to the specific antigen.
If there are not antibodies specific for lupus, the patient may stilI have lupus because lupus attacks and destroys…

Let's Try This
Troubled Waters A friend invited you to his birthday party the following
weekend. The celebration will be held in a public beach. You replied by
saying that you are hesitant to go because you found out that there are
many people who are invited to the party. Your friend on the other hand
assured you that you will be safe because all necessary health
protocols will be followed in the party to avoid transmission of the
Corona virus. What would you reply?
Processing Questions:

Topic is : SARS-CoV-2
Explain why this topic is important. In your response you must state which specific organism (specific plant, animal,..) is the pathogen’s host and why studying this pathogen is important. To answer this question fully, you need to do some external research to support, quantitatively (with numbers) why this topic is important. For example, if you choose a human pathogen, you should include answers to questions such as: what disease or health problems does it cause? How many people are affected or die annually? What are the economic impacts of the pathogen?
