“…The incidence of the various types of VRC varies widely among studies from different countries. This is probably due to divergence in sociodemographic aspects and health care systems [25] as well as differences regarding data sources, data collection methodology, diverging definitions of diagnoses allocated to specific VRC categories, presence of UVV programs, and pre-vaccination [1,20,22,24,[26][27][28][29] or postvaccination [19,[30][31][32] periods observed.
