BACKGROUND Varicella zoster virus (VZV) causes varicella and, later in the life of the host, may reactivate to cause herpes zoster (HZ). Because it is hypothesized that exposure to varicella may boost immunity to latent VZV, the vaccination-associated decrease in varicella disease has led some to suggest that the incidence of HZ might increase. We assessed the impact that varicella vaccination ...
A quadrivalent vaccine combining measles, mumps, rubella, and varicella antigens (MMRV) was developed to increase the coverage of varicella vaccine and reduce the number of injections children receive. Although the varicella antigen is as immunogenic in the latest formulation of MMRV vaccine as when it is administered alone, up to 14% of vaccine recipients do not achieve protective levels of an...
INTRODUCTION Varicella (chickenpox) can cause serious complications and admission to hospital. Several countries included the varicella vaccine in their immunization schedules. MATERIAL AND METHODS A descriptive and retrospective study of hospitalizations due to varicella and its complications was conducted in a referral center from 2005 to 2011. RESULTS A total of 1192 children with varice...
BACKGROUND/AIMS The transmission rate of air-borne infectious diseases may vary secondary to climate conditions. The study assessed time trends in the seasonality of hospitalized varicella cases in a temperate region in relation to climatic parameters prior to the implementation of universal varicella immunization. METHODS A retrospective descriptive study was conducted among all pediatric an...
complication of infection with maternal varicella before 20 weeks of pregnancy. Prospective studies in Europe and North America have shown that the incidence of congenital varicella syndrome in maternal varicella contracted in the first 20 weeks of pregnancy is about 1%–2%. Based on this estimated risk (1%), on an estimated risk of varicella infection during pregnancy of two maternal infections...
BACKGROUND Although live-attenuated varicella-zoster virus (VZV) vaccines have been proven to be safe and effective in preventing varicella and real-word evidence shows routine childhood immunization programs are effective in dramatically reducing varicella associated morbidity and mortality, varicella vaccine is not included in the National Immunization Program (NIP) in Hungary. The purpose of...
With continuing occurrence of varicella despite increasing vaccine coverage for the past 20 years, a case-based study, a case-control study, and an immunogenicity and safety study were conducted to address the impact of varicella vaccination in South Korea. Varicella patients under the age of 16 years were enrolled for the case-based study. For the case-control study, varicella patients between...
BACKGROUND In the Netherlands, incidence of physician's consultations and hospitalizations for varicella is low compared to other countries. Better knowledge about the severity of varicella among Dutch hospitalized patients is needed. Therefore, a medical record research was conducted among hospitalized patients with diagnosis varicella. METHODS Hospital admissions due to varicella in 2003-20...
A healthy 22-year-old man developed acute varicella pericarditis, characterised by an enanthem with diagnostic rising titres of varicella zoster antibodies but without the typical exanthem. This, the third reported case of varicella pericarditis, is the first to be documented without a typical varicella eruption.
To determine vaccine effectiveness (VE), a varicella outbreak in a highly vaccinated day-care center (DCC) population in Pennsylvania was investigated. In Pennsylvania, proof of immunity is required for children >or=12 months old for DCC enrollment. Questionnaires were administered to parents of children who had attended the DCC continuously during the study period (1 November 1999-9 April 2000...
