QUESTION #1 The following questions are based on the above video, but you may also use your textbook or other reputable source.

1a: What are the names and functions of immune cells that fight flu viruses?

1b: What are antibodies and why are they important to the immune response?

1c: How does the influenza virus spread?

QUESTION #2:

2a: Every year, a different strain of influenza virus arises and can lead to severe illness and sometimes death, especially in "high-risk" demographics. Young children and older individuals are considered the most susceptible groups in terms of acquiring the illness and succumbing to it. Why do you think this is? In your answer, consider how homeostasis must be maintained in response to viral infection and how this can vary between different age groups.

2b: Some people take non-steroidal anti-inflammatories (or NSAIDs) when they have the flu because it reduces fever and inflammation, which in turn, makes them feel better. Based on what you learned about inflammation, how do you think taking NSAIDs while having the flu might be reduce your ability to fight off the flu virus?

Second Paragraph

A vaccine is an agent that immunizes an individual against a certain pathogen, which is any foreign invader that attacks the body. There are several types of vaccines that work slightly differently from one another. When scientists create vaccines, they consider how your immune system responds to the invading organism, who needs to be vaccinated against the invading organism, and the best technology or approach for creating the vaccine.

Chose one of the following types of vaccines - describe what it is, how it works, and give an example of a vaccine that uses this type. In answering your question, you should use a valid resource and provide the URL along with your answer.** Examples of reliable sources include your textbook, a government website (.gov), an accredited university (.edu), or peer-reviewed scientific paper, etc. Newspaper articles, blogs, discredited (or retracted) peer-reviewed articles, or other potentially biased sources are not acceptable.

inactivated vaccine
live-attenuated vaccine
messenger RNA vaccine (or mRNA vaccine)
subunit, recombinant, polysaccharide, and/or conjugate vaccines (they all use the same approach)
toxoid vaccine
viral vector vaccine
Third Paragraph

There are many ways in which you can prevent the spread of influenza. Which one do you think is the most effective and why? Can the this same strategy also work for preventing the spread of the coronavirus that causes COVID-19? If not, include the strategy that you think works the best in helping to prevent or mitigate COVID-19.
