Pneumococcal conjugate vaccines in Taiwan: optimizing health gains in children and older adults through constrained optimization modeling: Pneumococcal conjugate vaccines optimization in Taiwan

•A model was used to establish the best combination of pneumococcal vaccines in Taiwan•The optimum combination would maximize overall health benefits within the country's budget•The 23-valent vaccine for older adults combined with the 10-valent vaccine for children was found to be optimal•These results help to inform the selection of vaccination strategies within a limited budget
