Vaccination in humanitarian crises: satisficing should no longer suffice

Area of Science:

• Public Health
• Epidemiology
• Vaccinology

Background:

• Numerous vaccination interventions exist to mitigate health risks in crisis-affected populations.
• However, delivering these vaccines effectively in crisis settings presents significant challenges.

Purpose of the Study:

• To examine the difficulties and factors influencing the implementation of vaccination interventions in crisis situations.
• To highlight the need for improved decision-making processes based on robust data.

Main Methods:

• Review of existing literature on vaccine delivery in crises.
• Analysis of factors affecting decision-making, including data availability, vaccine characteristics, and political considerations.

Main Results:

• Decision-making for vaccination in crises often relies on 'satisficing' due to sparse epidemiologic and effectiveness data.
• Limitations in vaccine presentation, formulation, storage, political factors, and lack of guidance exacerbate implementation difficulties.

Conclusions:

• Effective implementation of vaccination interventions in crises is hampered by data scarcity and logistical constraints.
• Future efforts must prioritize sound effectiveness studies to ensure evidence-based decision-making in humanitarian settings.
