This study updates previous work on modelling the incidence of varicella and Herpes Zoster (HZ) following the introduction of childhood varicella vaccination.

The impact of the epidemiology of varicella on zoster epidemiology is still debated.

​From the results of this study, ITP events seem unlikely after early childhood vaccines other than MMR.

This post licensure study assesses the long-term effectiveness of varicella vaccine and the impact on the epidemiology of varicella and HZ.
