Question 2

You are vaccinated against chickenpox as an infant and then when you are six you encounter the virus as one of your friends is suffering from chickenpox. How does your response to the vaccine (e.g.,your first exposure to the antigen)differ from the response to the virus when you are six (e.g.,your second exposure to the antigen)? What antibodies would be in your serum during the first and second response?
