What Would Be a Primary Advantage of Using an Attenuated

question 8

Multiple Choice

What would be a primary advantage of using an attenuated agent rather than just an antigen from that agent for a vaccine?

• A)This is actually a disadvantage-it's much more dangerous to use an attenuated agent over a subunit (single antigen)vaccine due to the possibility of reversion of the microbe to a pathogenic state.
• B)An attenuated agent strongly stimulates ONLY the antibody production (humoral response)of the adaptive immune system.This provides the best and strongest long-term protection.
• C)An attenuated agent strongly stimulates ONLY the cytotoxic T cell (CTL,cell-mediated)side of the adaptive immune system.This provides the best and strongest long-term protection.
• D)An attenuated agent strongly stimulates both the humoral (antibody)AND cell-mediated (T cell)portions of the adaptive immune response,giving the best comprehensive long-term protection available.
