  1. Each of the scenarios examined compares four strategies: a base case (no vaccination), a preventive strategy with routine vaccination at 9 months of age (“routine”), a preventive strategy with routine vaccination and a catch-up campaign up to 15 years of age (“routine + catch-up”), and a reactive vaccination strategy with routine vaccination and a catch-up campaign
