PMID: 12948367 Abstract Title:  Use of hospitalization and pharmaceutical prescribing data to compare the prevaccination burden of varicella and herpes zoster in Australia. Abstract:  The aims of the study were to compare the burden of varicella and herpes zoster in Australia. No national surveillance exists for varicella or herpes …

Introduction of varicella vaccination of children is predicted to increase herpes zoster for the first 40 to 60 years when the natural boosting of adults from the virus circulating among children ceases.

A case repot of a female infant with undiagnosed severe combined immunodeficiency who presented with disseminated vaccine-acquired varicella (VZV) and vaccine-acquired rubella infections at 13 months of age.

PMID:  Clin Exp Immunol. 2014 Dec ;178(3):459-69. PMID: 25046553 Abstract Title:  Vaccine-associated varicella and rubella infections in severe combined immunodeficiency with isolated CD4 lymphocytopenia and mutations in IL7R detected by tandem whole exome sequencing and chromosomal microarray. Abstract:  In areas without newborn screening for severe combined immunodeficiency (SCID), disease-defining infections may lead to diagnosis, and …

The risk of febrile seizures doubles with the MMRV vaccine compared to the MMR and varicella administered separately. Despite this risk, this paper still emphasizes the fact that MMRV enhances vaccine uptake due to preference of combination vaccines.

PMID: 24914115 Abstract Title:  Risk of febrile seizures after first dose of measles-mumps-rubella-varicella vaccine: a population-based cohort study. Abstract:  BACKGROUND: The combination measles-mumps-rubella-varicella (MMRV) vaccine currently used in Canada (Priorix-Tetra) may increase the risk of febrile seizures relative to the separate vaccines (MMR and varicella) …

Repetitive exposures to wild-type varicella virus have been shown to induce immunity to varicella.

PMID:  Clin Vaccine Immunol. 2014 Mar ;21(3):417-26. Epub 2014 Jan 15. PMID: 24429070 Abstract Title:  Influence of frequent infectious exposures on general and varicella-zoster virus-specific immune responses in pediatricians. Abstract:  Reexposure to viruses is assumed to strengthen humoral and cellular immunity via the secondary immune response. We studied the effects of frequent exposure to viral …
