Ebola could be eradicated through voluntary vaccination.

Area of Science:

• Epidemiology
• Game Theory
• Public Health

Background:

• Ebola virus disease (EVD) is a severe, highly fatal infectious disease.
• Transmission occurs through direct contact with bodily fluids.
• The rVSV-ZEBOV vaccine offers a promising intervention.

Purpose of the Study:

• To model the impact of individual vaccination decisions on population immunity.
• To assess the feasibility of Ebola eradication using game theory.

Main Methods:

• Developed a game-theoretic model of Ebola transmission.
• Incorporated individual rational choice in vaccination decisions.
• Performed uncertainty and sensitivity analyses.

Main Results:

• Selfishly optimal vaccination strategies result in coverage negligibly below herd immunity.
• Ebola eradication is mathematically feasible under specific conditions.

Conclusions:

• Voluntary vaccination programs, supported by public education, can lead to Ebola eradication.
• Findings are robust across various epidemiological model parameters.
