Summary Introduction
To analyze:
The need to receive a flu shot every year.
Given:
In the given case, Mr. J. is a old man, who is 80 years old and not happy to get a flu shot every year. It is known that the flu viruses undergo rapid mutation, which changes their protein coat.
Introduction:
The flu shot is a type of vaccine that provides immunity against the influenza virus. This vaccine is updated each year and recommended for those who are at high risk of catching a cold and cough. It contains a variety of attenuated strains of the influenza virus.

- Let’s say there are two closely related viruses, let’s call them Guernsey virus and Micro virus. These two viruses only infect epithelial cells. Their surface antigens are sufficiently similar that there are a number of shared epitopes between the two viruses. Choose one of the following: A) If you get infected and successfully recover from one virus, it’s quite possible that you’ll have neutralizing antibodies against the other. B) If you get infected and successfully recover from one virus, you’ll still be susceptible to the other one because the antigens aren’t exactly the same. C) If you get infected and successfully recover from one virus, it’s likely that getting infected with the other virus will be worse because of the common phenomena of antibody-dependent enhancement. D) Not enough information has been given.arrow_forwardWhy is it important to continue immunizing children in the United States against measles, even though it is a rare disease here?arrow_forwardElena developed chicken pox when she was in kindergarten.
