How to evaluate potential non-specific effects of vaccines: the quest for randomized trials or time for triangulation?

open access: yesExpert Review of Vaccines, 2018
Introduction: Emerging evidence suggests that vaccines, in addition to their disease-specific effects, have important non-specific effects (NSEs), which contribute to their overall effect on mortality and morbidity.
