1) Describe how the mammalian immune system responds to (i) a laceration, such as an injury from falling on a barbed-wire fence, and (ii) a viral infection.
2) Explain how the flu vaccination works and why it has a fairly low success rate.
This solution provides information on the mammalian immune response to a laceration or injury and viral infection. It then discusses the working of flu vaccine and reason behind its low success rate.
