Textbook Question
Chapter 50, Problem 6A
Why do we need to be repeatedly vaccinated for influenza viruses?
a. They attack only the helper T cells, thereby suppressing the immune system.
b. They alter their surface proteins and thus avoid immune recognition.
c. They don’t actually generate an immune response; the “flu” is actually an inflammatory response.
d. They are too small to serve as good antigens.

Students have asked these similar questions
In the text, the author describes the benefits of receiving vaccines. Are there
disadvantages? Why do you think some people might choose not to get vaccinated?
When we get sick we trust our immune system to protect us, but what happens when that system goes awry and ends up killing patients?
Question: What is Cytokine Storm, and how does it work? What happens during the immuneresponse to the Corona virus, which results in a high number of deaths?
Analyze and give a brief report.
Using what you know about viruses and the immune and lymphatic systems, construct a scientific explanation to describe how a vaccine works to provide immunity to the human body.
