Cholera vaccination for North American travelers is costly, with one case prevented costing $28.67 million and causing 105 adverse events. Routine vaccination is not recommended, but consider it for high-risk cholera regions.

Area of Science:

  • Public Health
  • Epidemiology
  • Health Economics

Background:

  • Cholera remains a threat in endemic and epidemic regions globally.
  • North American travelers to these areas are at risk of contracting cholera.
  • Assessing the cost-effectiveness of vaccination is crucial for public health policy.

Purpose of the Study:

  • To evaluate the clinical impact and financial cost of cholera vaccination for North American travelers.
  • To analyze the relationship between case attack rates and the cost per case prevented by vaccination.
  • To inform vaccination recommendations for travelers based on risk assessment.

Main Methods:

  • Decision analysis and decision tree modeling were employed.
  • A comprehensive review of scientific literature was conducted to determine outcome probabilities.

  • Partial economic evaluation and analysis of clinical impact, mortality, and vaccine-associated adverse events (VAAEs) were performed.

    • Main Results:

    • Preventing one case of cholera was estimated to cost $28.67 million.
    • The vaccination program was associated with 105 vaccine-associated adverse events (VAAEs) per case prevented.
    • Assumptions included a cholera incidence rate of 1 in 500,000 journeys to endemic regions.

    Conclusions:

    • Routine cholera vaccination for travelers to endemic areas is not cost-effective and therefore not recommended.
    • Vaccination should be considered for individuals traveling to regions with a high cholera transmission rate.
    • Risk-stratified recommendations are essential for optimizing public health interventions and resource allocation.
