Cost‑Benefit Simulation of Vaccination Strategies

Category: Epidemiological Modeling / Economic Analysis

Tools Used: R (custom functions, dplyr, ggplot2)

Description:

Developed a reproducible R workflow to evaluate the economic impact of vaccination programs . The project included:

Core simulation function to calculate vaccinated Number, cases averted, benefits, costs, net benefit, and benefit‑cost ratio (BCR).

Scenario analysis comparing pilot, smart rollout, and national programs in one consolidated table.

Sensitivity analysis across incidence and vaccination cost grids, producing a heatmap of net benefits.

State‑level extension for Sudan, reading inputs from CSV and generating results per state.

Exported results to CSV and Word for policy reporting.

Key Findings :

Pilot program showed positive net benefits with moderate coverage.

National rollout yielded the highest benefit‑cost ratio, demonstrating strong economic justification.

Sensitivity analysis revealed vaccination cost and incidence as critical drivers of net benefit.

State‑by‑state modeling provided localized insights for resource allocation.
