Two newly developed vaccine candidates (A and B) are tested in mice for their ability to elicit high concentrations of anti-meningococcal antibodies that would provide mucosal as well as bloodstream protection. Also, the ideal candidate vaccine should also provide long-lasting immunity to the infection.  The figure below shows the responses to a primary, followed by a secondary immunization to each of the two candidate vaccines. a) Which candidate vaccine elicits the preferred response? What are the three aspects of the preferred response that make it the candidate vaccine of choice?  b) What is the likely composition of each vaccine and what evidence from the information above are used to lead to your conclusions? c) To confirm the choice of the preferred candidate vaccine, what type of additional information from the vaccine trials in mice shown above would support this conclusion? Name two additional features of the secondary antibody response to each candidate vaccine that could be…

Each year the Centers for Disease Control and Prevention publish a schedule of recommended vaccinations for infants, children, adolescents, and adults.
