Prediction of immunisation performance

Vaccines are extremely powerful disease prevention agents and have the potential to save millions of lives. Tremendous scientific progress has been made in the past decade with several new vaccines licensed, including those to prevent pneumococcal and rotavirus disease—the two leading killers of young children in developing countries. Thanks to concerted efforts by stakeholders through the GAVI Alliance, many of these new vaccines are now accessible to the lowest-income countries and the children who live there.
