Background. A 15-year postmarketing evaluation of the impact of varicella vaccine on the age distribution of varicella disease is being conducted at Kaiser Permanente Medical Care Program, Northern California (KPMCP). We report on a baseline assessment of the age-specific incidence and hospitalization rates of varicella and herpes zoster that was conducted before vaccine introduction. Methods. To assess the annual incidence of varicella, a telephone survey was conducted in a random sample of… Expand
Impact of Vaccination on the Epidemiology of Varicella: 1995–2009
TLDR
In the 15 years after the introduction of varicella vaccine, a major reduction invaricella incidence and hospitalization was observed with no evidence of a shift in the burden of varICElla to older age groups. Expand
Use of hospitalization and pharmaceutical prescribing data to compare the prevaccination burden of varicella and herpes zoster in Australia
TLDR
Herpes zoster has a higher burden of disease than varicella, and must be a component of disease surveillance in order to determine the full impact of vaccination on the epidemiology ofvaricella zoster virus (VZV). Expand
Herpes Zoster–Related Hospitalizations and Expenditures Before and After Introduction of the Varicella Vaccine in the United States
TLDR
The rate of herpes zoster-related hospitalizations and the associated hospital charges before and during the promotion of varicella vaccination in the United States was estimated, and there was a significant increase in HZHDs and associated charges, disproportionately among older adults. Expand
Varicella-Related Hospitalization and Emergency Department Visit Rates, Before and After Introduction of Varicella Vaccine, Among White and Black Children in Hamilton County, Ohio
TLDR
Varicella-related hospitalization and ED visit rates decreased significantly for both white and black children in Hamilton County, Ohio, after the introduction of varicella vaccine, and the racial disparity found before licensure decreased after licensure. Expand
Long-term Effectiveness of Varicella Vaccine: A 14-Year, Prospective Cohort Study
TLDR
It is confirmed that varicella vaccine is effective at preventing chicken pox, with no waning noted over a 14-year period, and the study data suggest thatvaricella vaccination may reduce the risks of HZ in vaccinated children. Expand
The incidence of varicella and herpes zoster in Taiwan during a period of increasing varicella vaccine coverage, 2000–2008
SUMMARY The introduction and the widespread use of the varicella vaccine in Taiwan has led to a 75–80% decrease in the incidence of varicella in children. However the vaccine's long-term impact onExpand
Do varicella vaccination programs change the epidemiology of herpes zoster? A comprehensive review, with focus on the United States
  • R. Harpaz
  • Medicine
  • Expert review of vaccines
  • 2019
TLDR
This comprehensive review provides reassurance for countries considering varicella vaccination that an effective program can reducevaricella morbidity and mortality while reducing the likelihood of HZ among children, and potentially, over time, across the entire population. Expand
Varicella-related hospitalizations in the vaccine era
  • A. Ratner
  • Medicine
  • The Pediatric infectious disease journal
  • 2002
TLDR
There has not been a significant decrease in total or first diagnosis VRHD since the varicella vaccine became available, and current coverage levels are below those used in prelicensure models. Expand
Decline in Varicella-Related Hospitalizations and Expenditures for Children and Adults After Introduction of Varicella Vaccine in the United States
TLDR
This national analysis indicates a clinically and statistically significant reduction invaricella-related hospitalizations for children and adults associated with childhood varicella immunization in the United States and a corresponding significant decrease in hospital charges. Expand
The Burden of Varicella Complications Before the Introduction of Routine Varicella Vaccination in Germany
TLDR
The data show that the severity of varicella complications in healthy children has been previously underestimated and is related to increasing age and immunosuppression. Expand

Epidemiology of primary varicella and herpes zoster hospitalizations: the pre-varicella vaccine era.
TLDR
Analysis of population-based hospital discharge data is a feasible means of monitoring the impact of varicella immunization on severe morbidity due to primary varicello and herpes zoster in the prevaccine era. Expand
The epidemiology of varicella and its complications.
TLDR
Varicella in adults and varicella complications in general may be more frequent than previously estimated. Expand
Postmarketing evaluation of the safety and effectiveness of varicella vaccine.
TLDR
In this study population of 89753 children and adults, the varicella vaccine appeared to have a favorable safety profile, and rates ofvaricella-like rash and of breakthrough cases were both low and consistent with the rates observed in prelicensure studies. Expand
Age-specific risks of varicella complications.
Previous estimates of the age-specific risks of varicella-associated encephalitis and death (the only two varicella complications for which national data are available) have been based on age dataExpand
Decreasing rates of hospitalization for varicella among young adults.
TLDR
In unconditional logistic regression risk factor modeling for varicella hospitalization, personnel at highest risk of hospitalization had foreign homes of record, were most junior in rank, had < or = 2 years of military service, were Filipino or black, and served in the Navy. Expand
Epidemiology of herpes zoster in children and adolescents: a population-based study.
TLDR
Medical records were reviewed for all 173 cases of herpes zoster diagnosed among residents of Rochester, Minnesota, less than 20 years of age during the period 1960 through 1981, and chickenpox in the first year of life was found to be a risk factor for childhood zoster. Expand
Community impact of childhood varicella infections.
TLDR
Parent-reported incidence data indicate that varicella infections are increasing in preschool children, and this shift to infections in younger children may be related to the increased use of out-of-home care for infants and young children. Expand
Theoretical epidemiologic and morbidity effects of routine varicella immunization of preschool children in the United States.
TLDR
Although implementation of a vaccination program resulted in a shift in the age distribution of remaining varicella cases toward older ages with higher complication rates, the overall reduction in cases resulted in decreased morbidity as measured by overall number of hospitalizations and number of primary cases. Expand
Increasing incidence of varicella hospitalizations in United States Army and Navy personnel: are today's teenagers more susceptible? Should recruits be vaccinated?
TLDR
Multivariate analysis of the navy data confirmed increasing time-related trends of risk, suggesting a national temporal trend of increased varicella susceptibility in US teenagers and young adults. Expand
Population-based studies of varicella complications.
TLDR
Overall, varicella accounts for approximately 4,000 hospitalizations and 364,000 physician office visits annually in the United States and represents an important continuing source of childhood and adult morbidity. Expand
