herpes zoster in children vaccinated against varicella-zoster virus: experience in our hospital. 201525456110
varicella-zoster virus vaccination under the exogenous boosting hypothesis: two ethical perspectives.the varicella-zoster virus (vzv) causes two diseases: varicella ('chickenpox') and herpes zoster ('shingles'). vzv vaccination of children reduces exposure to chickenpox in the population and it has been hypothesized that this could increase the prevalence of shingles. this 'exogenous boosting' effect of vzv raises an important equity concern: introducing a vaccination program could advance the health of one population group (children) at the expense of another (adults and elderly). we discuss t ...201425454883
varicella-zoster virus and virus dna in the blood and oropharynx of people with latent or active varicella-zoster virus infections.varicella-zoster virus (vzv) can be detected in the blood from approximately 5 days before to 4 days after varicella. vzv dna, primarily in t-lymphocytes, is detected as early as 8-10 days prior to rash and can persist for a week. the duration and magnitude of vzv dnaemia correlates with immune status and the efficacy of antiviral therapy. vzv dna is also readily detected in the oropharynx just prior to rash and for 1-2 weeks thereafter. detection of vzv dna in blood and saliva has been useful f ...201425453570
disseminated, persistent, and fatal infection due to the vaccine strain of varicella-zoster virus in an adult following stem cell transplantation.live attenuated varicella vaccine is recommended for healthy individuals who are susceptible to varicella. although the vaccine is safe, effective, and used worldwide, serious adverse events have been reported, mainly in immunocompromised patients who subsequently recovered. here, we describe the fatality of an immunocompromised patient who received the varicella vaccine. his medical history provides a cautionary lens through which to view the decision of when vaccination is appropriate. a middl ...201525452596
varicella vaccination coverage inverse correlation with varicella hospitalizations in spain.varicella vaccines available in spain were marketed in 1998 and 2003 for non-routine use. since 2006 some regions included universal varicella vaccination in their regional routine vaccination programs at 15-18 months of age. regions without universal vaccination in toddlers, but instead with the strategy of vaccinating susceptible adolescents, reached different varicella vaccination coverage through private market. this study shows the correlation between severe varicella zoster virus infection ...201425444825
