UNIVAC is a single universal vaccine impact and cost-effectiveness decision support model with a standardized, accessible Excel-based interface and a familiar set of input steps and outputs. Input estimates of age-specific disease burden, age/dose specific vaccine coverage and effectiveness allow for a simple evaluation of direct vaccination impact on health outcomes.

Additional input parameters can be included to evaluate indirect effects, which may be important for the evaluation of several vaccines. The tool features automated calculations, options for sensitivity analysis and automatically generated results charts and figures.

UNIVAC: evaluating vaccine impact and cost-effectiveness

The UNIVAC model currently includes options to evaluate the impact and cost-effectiveness of vaccines that prevent Haempohilus influenzae, pneumococcal disease, rotavirus, human papillomavirus and meningococcal disease. Future development work will prioritize evaluation of other new vaccines available and in the pipeline, including dengue.
