Is it a Lemon or a Lyme?

A Case Study on the Decision to Vaccinate or Not

By Kate Rittenhouse-Olson

Is it a Lemon or a Lyme?


 

Abstract

This dilemma case was designed for a junior level immunology course. It could also be used in a microbiology or bacteriology course where the emphasis is on treatment as well as disease. Although the case revolves around a particular microbe that causes Lyme disease, the central question is “Should a person get vaccinated given the associated risks and benefits?”  Students are assigned to one of five groups that cover the epidemiology, etiology and pathology, prevention and treatment, laboratory diagnosis, and vaccine for the disease; each group is given a question to research, which they then present on to the rest of the class.

Overview

Objectives

  • Judge the relative risk of developing Lyme disease in various regions, at different times of the year, and with different activities.
  • Discuss the pathologies caused by the bacteria in Lyme disease.
  • Compare the signs and symptoms of the various stages of Lyme disease.
  • Describe the etiology of Lyme disease.
  • Evaluate appropriate treatment for patients with each stage of the disease and potential adverse side effects of treatment.
  • Describe laboratory assays, including PCR, Western blotting, enzyme immunoassays, and immunofluorescent assays.
  • Describe the vaccine protocol as well as the efficacy, risks, costs, and benefits of the vaccine.
  • Realize that health care decisions should be made after obtaining the knowledge needed to make an informed decision.
