The systematic review by Zhang et al. recently published on IJPH (1) provides an important update on the status of vaccine literacy (VL) and related measurement tools. While the Authors highlight the role of VL in overcoming vaccine hesitancy and increasing immunization rates, they also conclude that the tools used in the selected studies were “ limited ” in relation to the complexity of the in fl uencing factors, as they were not designed to speci fi cally assess VL skills, but were adapted from those used to measure health literacy (HL) in chronic patients (2).
