Summary Introduction
To describe: What does the action of Jenner using cowpox virus to induce an immune response against smallpox tell regarding the antigenic properties of two different viruses.
Introduction: The smallpox disease, caused by the variola virus, was a fatal disease common in the earlier centuries. Edward Jenner proposed the thought that cowpox infection could provide immunity against smallpox. His procedure of infecting a known harmless substance to confer immunity to a rather lethal infection is referred to as vaccination.

What is one reason SARS-CoV-2 can remain undetected in a person?
a.)it isn't able to replicate unless you are also sick with another type of virus
b.)its genome produces proteins that prevent our immune system from noticing it
c.)it causes your immune system to shut down
d.)it is prevented from infecting a cell for one year after entering your body
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.

- When the patient's mother expresses concern about his sister being reinfected with chickenpox, what is the most appropriate response? A) Your concerns are valid, but his sister developed an active natural immunity to chickenpox because she has already been infected. B) Your concerns are valid and there is a high likelihood that his sister will become infected again. We should probably administer the vaccine. C) Your concerns are valid and there is no way to protect his sister from becoming reinfected except to keep her at least 15 feet from your son at all times. D) Your concerns are valid and if his sister is reinfected, her symptoms will be less severe than her initial chickenpox infection.arrow_forwardA researcher performs an experiment where he infects 2 mice (Mouse A and Mouse B) with herpes simplex virus (HSV). To measure the cytotoxicity of CD8+ T cells from Mouse A, he isolates CD8+ T cells from Mouse A and co-cultures them with a mixture of HSV-infected spleen cells from Mouse B. A day later, he checks the co-culture, but none of the infected spleen cells from Mouse B have been killed.
