RESUMO

Herpes zoster (shingles) causes significant morbidity in immune compromised hosts and older adults. Whereas a vaccine is available for prevention of shingles, its efficacy declines with age. To help to understand the mechanisms driving vaccinal responses, we constructed a multiscale, multifactorial response network (MMRN) of immunity in healthy young and older adults immunized with the live attenuated shingles vaccine Zostavax. Vaccination induces robust antigen-specific antibody, plasmablasts, and CD4+ T cells yet limited CD8+ T cell and antiviral responses. The MMRN reveals striking associations between orthogonal datasets, such as transcriptomic and metabolomics signatures, cell populations, and cytokine levels, and identifies immune and metabolic correlates of vaccine immunity. Networks associated with inositol phosphate, glycerophospholipids, and sterol metabolism are tightly coupled with immunity. Critically, the sterol regulatory binding protein 1 and its targets are key integrators of antibody and T follicular cell responses. Our approach is broadly applicable to study human immunity and can help to identify predictors of efficacy as well as mechanisms controlling immunity to vaccination.

RESUMO

BACKGROUND: Herpes zoster vaccination rates remain low despite longstanding national recommendations to vaccinate immunocompetent adults aged ≥ 50 years. The Advisory Committee on Immunization Practice (ACIP) updated its recommendations for recombinant zoster vaccine (RZV) in October 2021 to include immunocompromised adults aged ≥19 years. OBJECTIVE: To assess practices, attitudes, and knowledge about RZV, barriers to recommending RZV, and likelihood of recommending RZV to patients with various immunocompromising conditions. DESIGN: Mail and internet-based survey conducted from May through July 2020. PARTICIPANTS: General internists and family physicians throughout the USA. MAIN MEASURES: Survey responses. KEY RESULTS: The response rate was 66% (632/955). Many physicians were already recommending RZV to immunocompromised populations, including adults ≥50 years with HIV (67% of respondents) and on recombinant human immune modulator therapy (56%). Forty-seven percent of respondents both stocked/administered RZV and referred patients elsewhere, frequently a pharmacy, for vaccination; 42% did not stock RZV and only referred patients. The majority agreed pharmacies do not inform them when RZV has been given (64%). Physicians were generally knowledgeable about RZV; however, 25% incorrectly thought experiencing side effects from the first dose of RZV that interfere with normal activities was a reason to not receive the second dose. The top reported barrier to recommending RZV was experience with patients declining RZV due to cost concerns (67%). Most physicians reported they would be likely to recommend RZV to immunocompromised patients. CONCLUSION: Most primary care physicians welcome updated ACIP RZV recommendations for immunocompromised adults. Knowledge gaps, communication issues, and financial barriers need to be addressed to optimize vaccination delivery.

RESUMO

BACKGROUND: Kidney transplant recipients receive maintenance immunosuppressive therapy to avoid allograft rejection resulting in increased risk of infections and infection-related morbidity and mortality. Approximately 98% of adults are infected with varicella zoster virus, which upon reactivation causes herpes zoster. The incidence of herpes zoster is higher in kidney transplant recipients than in immunocompetent individuals, and kidney transplant recipients are at increased risk of severe herpes zoster-associated disease. Vaccination with adjuvanted recombinant glycoprotein E subunit herpes zoster vaccine (RZV) prevents herpes zoster in older adults with excellent efficacy (90%), and vaccination of kidney transplant candidates is recommended in Danish and international guidelines. However, the robustness and duration of immune responses after RZV vaccination, as well as the optimal timing of vaccination in relation to transplantation remain unanswered questions. Thus, the aim of this study is to characterize the immune response to RZV vaccination in kidney transplant candidates and recipients at different timepoints before and after transplantation. METHODS: The Herpes Virus Infections in Kidney Transplant Patients (HINT) study is a prospective observational cohort study. The study will include kidney transplant candidates on the waiting list for transplantation (n = 375) and kidney transplant recipients transplanted since January 1, 2019 (n = 500) from all Danish kidney transplant centers who are offered a RZV vaccine as routine care. Participants are followed with repeated blood sampling until 12 months after inclusion. In the case of transplantation or herpes zoster disease, additional blood samples will be collected until 12 months after transplantation. The immune response will be characterized by immunophenotyping and functional characterization of varicella zoster virus-specific T cells, by detection of anti-glycoprotein E antibodies, and by measuring cytokine profiles. DISCUSSION: The study will provide new knowledge on the immune response to RZV vaccination in kidney transplant candidates and recipients and the robustness and duration of the response, potentially enhancing preventive strategies against herpes zoster in a population at increased risk. TRIAL REGISTRATION: ClinicalTrials.gov (NCT05604911).

RESUMO

BackgroundHerpes zoster (HZ) affects 1 in 3 persons in their lifetime, and the risk of HZ increases with increasing age and the presence of immunocompromising conditions. In Spain, vaccination guidelines were recently updated to include the recommendation of the new recombinant zoster vaccine (RZV) for certain risk groups.AimTo describe the epidemiology of HZ-related hospitalisations in Spain in order to prioritise vaccination recommendations and define a baseline to monitor the effectiveness of vaccination policies.MethodsRetrospective study using the National Health System's Hospital Discharge Records Database, including all HZ-related hospitalisations from 1998 to 2018.ResultsThe 65,401 HZ-related hospitalisations, corresponded to an annual mean hospitalisation rate of 6.75 per 100,000 population. There was an increasing trend of HZ hospitalisations over the study period. This rate was higher in males and older age groups, particularly over 65 years. Comorbidities with higher risk of readmission were leukaemia/lymphoma (RR 2.4; 95% CI: 2.3-2.6) and solid malignant neoplasm (RR 2.2; 95% CI: 2.1-2.4). Comorbidities associated with higher risk of mortality were leukaemia/lymphoma (RR 2.9; 95% CI: 2.7-3.2), solid malignant neoplasm (RR 2.9; 95% CI: 2.7-3.1) and HIV infection (RR 2.2; 95% CI: 1.8-2.7).ConclusionOf all patients hospitalised with HZ, those with greater risk of mortality or readmission belonged to the groups prioritised by the current vaccination recommendations of the Spanish Ministry of Health. Our study provided relevant information on clinical aspects of HZ and established the base for future assessments of vaccination policies.

RESUMO

OBJECTIVES: Vaccination is the most effective way to prevent herpes zoster (HZ) and related complications. This study aimed to investigate the preference of HZ vaccine among older people. STUDY DESIGN: A discrete choice experiment was performed. METHODS: In total, 178 adults aged ≥50 years were invited to choose between HZ vaccination scenarios using six vaccine attributes. Two equations were used to calculate participants' willingness to pay for the vaccine and their predicted choice probability. RESULTS: The attributes that significantly influenced participants' vaccine choices were lower cost, higher effectiveness, reduced side-effects and vaccination of others in their surroundings. CONCLUSIONS: Improving medical insurance coverage or reducing the cost of the HZ vaccine will encourage more people to be vaccinated, resulting in reduced burden of disease among older people.

RESUMO

OBJECTIVES: Insufficient adult vaccination coverage rates remain an international challenge. This nationwide study aimed at exploring vaccination coverage and predictors of influenza, pneumococcal, herpes zoster, tetanus, measles, and hepatitis B vaccine uptake, following the recommendations of the National Immunization Program for adults. STUDY DESIGN: This was a multicenter, mixed-methods study conducted at 23 primary care units in six different regions of Greece. METHODS: A pretested questionnaire was administered to three randomly selected adults who visited each practice daily for 30 consecutive working days. RESULTS: Among the 1571 participants, vaccination coverage for influenza in the high-risk groups was 55%, 36% for pneumococcal disease, 12% for herpes zoster (HZ), 21% for tetanus, 33% for measles, and 11% for hepatitis B. Perception of low susceptibility to disease due to good health status, concerns about side-effects and vaccines' efficacy, and mistrust in pharmaceutical companies were among common factors associated with the vaccines uptake. The strongest factor associated with the participants' vaccination status was their doctor's recommendation (odds ratio [95% confidence interval] influenza: 6.06 [4.52-8.14], pneumococcal disease: 15.73 [10.98-22.52], HZ: 17.01 [9.05-31.96], tetanus: 23.93 [16.20-35.35], measles: 33.47 [16.85-66.47], and hepatitis B: 73.92 [17.47-312.74]). Being well-informed about each vaccine was also a predictor of its uptake. CONCLUSIONS: Vaccination coverage was suboptimal and especially low in tetanus, HZ, and hepatitis B immunization. Person-centered approach, with provision of appropriate information about vaccines' safety and efficacy, responding to each patient's needs, as well as physicians' strong recommendation for vaccination are considered crucial to advocate against the spread of vaccine misinformation and increase vaccination coverage.

RESUMO

Herpes zoster is a painful dermatomal cutaneous eruption resulting from reactivation of the latent varicella-zoster virus. Patients with inflammatory bowel diseases have an increased risk of shingles compared with the general population and this risk can be increased with the use of immunosuppressive therapy. Live zoster vaccine and recombinant zoster vaccine have shown efficacy for the prevention of herpes zoster. The recombinant zoster vaccine seems to offer greater efficacy and long-term protection profile compared with the life zoster vaccine. However, their use in clinical practice still is unclear and updated vaccination recommendations are lacking. This review discusses the risk for shingles in patients with inflammatory bowel diseases, available vaccines, and their efficacy and safety profiles. We also provide guidance on who, when, and how to vaccinate for herpes zoster in routine clinical practice among patients with inflammatory bowel diseases.

RESUMO

Vaccine uptake in adult immunisation programs is often suboptimal. We aimed to assess the impact of the structured older persons health assessment (health assessment) on herpes zoster (zoster) vaccine uptake in Australia. We used national general practice electronic medical records (MedicineInsight) of encounters with patients aged 75-79 years because these patients were age-eligible for both free zoster vaccines and health assessments in the two years following the addition of zoster vaccine to the national immunisation program (Nov 2016-Dec 2018). Due to repeated encounters, we used generalized estimating equations with each patient treated as a clustering variable to analyse the comparison of rates of zoster vaccine administration during encounters where a health assessment was provided versus encounters where the health assessment was not provided. In analyses there were 31,876 patients with a total of 266,204 eligible general practice encounters. Of the 5018 encounters where a health assessment was provided, 592 zoster vaccinations also occurred on the same day (118.0/1000 encounters); for the 261,186 encounters where no health assessment was provided, 9226 zoster vaccinations occurred (35.3/1000 encounters). Zoster vaccine was more likely to be administered during a general practice encounter with a health assessment compared to encounters without one (adjusted odds ratio 2.99; 95% CI: 2.76-3.23). In conclusion, the structured older persons health assessment, which acts as both an incentive and a reminder for healthcare providers to recommend vaccinations in adults improves uptake of zoster vaccine in eligible adults. Such interventions may have a role in improving vaccine uptake among older adults.

RESUMO

BACKGROUND: Herpes zoster increases the burden on the elderly in an aging society. Although an effective vaccine licensed by China Food and Drug Administration in 2019 was introduced into the market in June 2020, the willingness and influencing factors of herpes zoster vaccines in Chinese adults ≥ 50-years-old during coronavirus disease-2019 pandemic are yet to be elucidated. METHODS: An online questionnaire survey was conducted using a simple random sampling method in October 2021 for viewers of the broadcast program. A binary logistic regression and multiple response analysis were conducted for herpes zoster vaccine and vaccination willingness. Pareto's graphs were plotted to present the multiple-choice questions of influencing factors. RESULTS: A total of 3838 eligible participants were included in this study. Among them, 43.02% intended to be vaccinated, including 10.34% self-reported about receiving at least one shot of shingles vaccine, 30.22% declined, and 26.76% were hesitant. This population comprised a large proportion of middle-aged and older people (≥ 50-years-old) who have not experienced an episode of herpes zoster (54.98%) or are unaware of the virus (33.22%). The strongest determinants of vaccine hesitancy among older people were education background of Master's degree or above compared to senior high or equivalent and below, personal monthly income < 3000 RMB compared to 3000-5999 RMB, and living in a rural area. CONCLUSIONS: The willingness to get shingles vaccines can be improved further. Professional education and credible recommendation might prompt the elderly to improve their willingness and reassure them of the safety and efficacy of the vaccine. Also, accessibility and affordability should also be improved in the future.

RESUMO

BACKGROUND: Herpes zoster (HZ) is a common skin disease resulting from a regionally limited reactivation of a latent infection with the varicella zoster virus (VZV). Despite its usually self-limiting course, HZ is associated with a considerable individual and public health burden of disease, particularly due to its high rate of postherpetic neuralgia (PHN). OBJECTIVES: To improve knowledge of the current recommendations for the prevention, diagnosis and treatment. MATERIALS AND METHODS: Narrative review and summary of current guideline recommendations. RESULTS: In Germany, the recombinant VZV subunit zoster vaccine is recommended for all adults of 60+ years and for immunocompromised persons of 50+ years. The diagnosis of HZ is clinical; in case of uncertainty, laboratory investigations can help confirm the diagnosis. For patients with HZ ophthalmicus, HZ oticus or neurological complications, an interdisciplinary approach is advantageous. Antiviral treatment should be started as early as possible; various factors, including the duration and location of the disease, the patient's age and signs of a complicated course, serve to determine the indication to initiate an antiviral medication. The choice of the appropriate treatment depends, among other factors, on the intravenous availability, comorbidities and intake preferences. Early and sufficient analgesic treatment according to the WHO pain ladder and, if required, with anticonvulsant adjuvants is necessary to treat acute pain and to reduce the risk for PHN. CONCLUSION: Implementation of the current recommendations for the prevention, diagnosis and treatment of HZ and PHN is important to reduce the high burden of disease and improve quality of life of the patients.

RESUMO

BACKGROUND: Efficacy of the live-attenuated herpes zoster (HZ) vaccine (ZVL) wanes substantially over time. We evaluated immunogenicity and safety of the adjuvanted recombinant zoster vaccine (RZV) in previous ZVL recipients. METHODS: Adults aged ≥65 years who were previously vaccinated with ZVL ≥5 years earlier (n = 215) were group-matched with ZVL-naive individuals (n = 215) and vaccinated with RZV. Glycoprotein E (gE)-specific humoral and cell-mediated immune responses and the correlation between them, polyfunctional gE-specific CD4 T-cell responses, safety, and confirmed HZ cases were assessed. RESULTS: Through 12 months after dose 2, anti-gE antibody concentrations, gE-specific CD4 T-cell frequencies, and activation marker profiles were similar between groups. Safety outcomes were also similar. No HZ episodes were confirmed. CONCLUSIONS: RZV induced strong humoral and polyfunctional cell-mediated immune responses that persisted above prevaccination levels through 1 year after dose 2 in adults aged ≥65 years irrespective of previous ZVL vaccination. The RZV safety profile was not affected. CLINICAL TRIALS REGISTRATION: NCT02581410.

RESUMO

BACKGROUND: Shingrix (recombinant zoster vaccine) was licensed to prevent herpes zoster, dispensed as 2 doses given 2-6 months apart among adults aged ≥50 years. Clinical trials yielded efficacy of >90% for confirmed herpes zoster, but post-market performance has not been evaluated. Efficacy of a single dose and a delayed second dose and efficacy among persons with autoimmune or immunosuppressive conditions have not been studied. We aimed to assess post-market vaccine effectiveness of Shingrix. METHODS: We conducted a cohort study among Medicare Part D community-dwelling beneficiaries aged >65 years. Herpes zoster was identified using a medical office visit diagnosis with treatment, and postherpetic neuralgia was identified using a validated algorithm. We used inverse probability of treatment weighting to improve cohort balance and marginal structural models to estimate hazard ratios. RESULTS: We found a vaccine effectiveness of 70.1% (95% confidence interval [CI], 68.6-71.5) and 56.9% (95% CI, 55.0-58.8) for 2 and 1 doses, respectively. The 2-dose vaccine effectiveness was not significantly lower for beneficiaries aged >80 years, for second doses received at ≥180 days, or for individuals with autoimmune conditions. The vaccine was also effective among individuals with immunosuppressive conditions. Two-dose vaccine effectiveness against postherpetic neuralgia was 76.0% (95% CI, 68.4-81.8). CONCLUSIONS: This large real-world observational study of the effectiveness of Shingrix demonstrates the benefit of completing the 2-dose regimen. Second doses administered beyond the recommended 6 months did not impair effectiveness. Our effectiveness estimates were lower than the clinical trials estimates, likely due to differences in outcome specificity.

RESUMO

PURPOSE: To examine the effectiveness of the recombinant zoster vaccine (RZV) for preventing herpes zoster ophthalmicus (HZO) in the general United States population. DESIGN: Retrospective, observational cohort study. PARTICIPANTS: Individuals enrolled in the OptumLabs Data Warehouse (OLDW; OptumLabs, Cambridge, MA) who were age eligible for herpes zoster (HZ) vaccination (≥50 years of age) from 2018 through 2019. The OLDW is a longitudinal, de-identified administrative claims and electronic health record database of patients in the United States with commercial insurance, Medicare Part D, or Medicare Advantage METHODS: Patients were required to have 365 days or more of continuous enrollment to be eligible. Those with a diagnosis code of HZ or an immunocompromising condition within 1 year before study inclusion were excluded. Vaccination with the RZV was ascertained by Current Procedural Terminology codes, and HZO was ascertained by International Classification of Diseases, Tenth Revision, codes. Cox proportional hazards regression models were used to estimate the hazard ratio of HZO associated with RZV, and inverse-probability weighting was used to control for confounding. Vaccine effectiveness was calculated from hazard ratios. MAIN OUTCOME MEASURES: Incidence of HZO in vaccinated versus unvaccinated person-times and vaccine effectiveness were assessed. RESULTS: From January 1, 2018, through December 31, 2019, a total of 4 842 579 individuals were included in this study. One hundred seventy-seven thousand two hundred eighty-nine (3.7%) received 2 valid doses of RZV. The incidence rate of HZO was 25.5 cases (95% confidence interval [CI], 17.4-35.8 cases) per 100 000 person-years in the vaccinated group compared with 76.7 cases (95% CI, 74.7-78.7 cases) in the unvaccinated group. The overall adjusted effectiveness of RZV against HZO was 89.1% (95% CI, 82.9%-93.0%). CONCLUSIONS: The effectiveness of RZV against HZO in individuals 50 years of age and older is high in a clinical setting. However, the low vaccination rate in this study highlights the public health need to increase HZV use. Ophthalmologists can play an important role in recommending vaccination to eligible patients.

RESUMO

Current vaccination policy in most high-income countries aims to counteract the decline in cell-mediated immunity to varicella zoster virus that occurs with advancing age or immunosuppression. The aim of this review was to describe the burden of illness associated with herpes zoster (HZ) and post-herpetic neuralgia (PHN) risks and their impact on the social and common life in infected people. The effectiveness/efficacy and cost effectiveness of the immunization strategy will be presented through the review of the literature relevant to the live attenuated HZ vaccine (ZLV) licensed in 2006 and the recombinant HZ vaccine (RZV). The latter has very recently been approved to protect aged people aged ≥ 50 years against HZ morbidity including its complications, and associated health-care costs. Finally, this review also provides data with respect of precautions of using and safety of ZVL and RVZ.

RESUMO

Varicella zoster virus (VZV) is a pathogenic human herpes virus that causes chickenpox as a primary infection, after which it persists for a long time and latently in the peripheral ganglia. Decades later, the virus can reactivate spontaneously, or after exposure to a number of triggering factors, causing herpes zoster (shingles). The reasons for the long-term persistence of VZV are gradually being revealed, but some issues remain unknown at the moment. Chickenpox and its complications are especially difficult in immunocompromised patients, but they are often found in people without risk factors. The most frequent and important complication of VZV reactivation is postherpetic neuralgia; encephalitis, segmental motor weakness and myelopathy, cranial neuropathies, and gastrointestinal complications often develop. The only scientifically proven effective and affordable way of mass prevention at the moment is vaccination. Chickenpox vaccines are safe and effective in preventing morbidity and mortality associated with the disease.

RESUMO

BACKGROUND: The incidence of herpes zoster is up to 9 times higher in immunosuppressed solid organ transplant recipients than in the general population. We investigated the immunogenicity and safety of an adjuvanted recombinant zoster vaccine (RZV) in renal transplant (RT) recipients ≥18 years of age receiving daily immunosuppressive therapy. METHODS: In this phase 3, randomized (1:1), observer-blind, multicenter trial, RT recipients were enrolled and received 2 doses of RZV or placebo 1-2 months (M) apart 4-18M posttransplant. Anti-glycoprotein E (gE) antibody concentrations, gE-specific CD4 T-cell frequencies, and vaccine response rates were assessed at 1M post-dose 1, and 1M and 12M post-dose 2. Solicited and unsolicited adverse events (AEs) were recorded for 7 and 30 days after each dose, respectively. Solicited general symptoms and unsolicited AEs were also collected 7 days before first vaccination. Serious AEs (including biopsy-proven allograft rejections) and potential immune-mediated diseases (pIMDs) were recorded up to 12M post-dose 2. RESULTS: Two hundred sixty-four participants (RZV: 132; placebo: 132) were enrolled between March 2014 and April 2017. gE-specific humoral and cell-mediated immune responses were higher in RZV than placebo recipients across postvaccination time points and persisted above prevaccination baseline 12M post-dose 2. Local AEs were reported more frequently by RZV than placebo recipients. Overall occurrences of renal function changes, rejections, unsolicited AEs, serious AEs, and pIMDs were similar between groups. CONCLUSIONS: RZV was immunogenic in chronically immunosuppressed RT recipients. Immunogenicity persisted through 12M postvaccination. No safety concerns arose.

RESUMO

The adjuvanted recombinant glycoprotein E herpes zoster (HZ) vaccine is superior to the live attenuated HZ vaccine, with an efficacy >90% against HZ in healthy immunocompetent adults aged ≥50 years after vaccination. In pivotal studies, the efficacy of the new vaccine varied very little with the age of the vaccinee and decreased only by 5-10% in the 3.5 years after immunization. This nonlive vaccine was successfully administered to small cohorts of immunocompromised individuals; initial trials showed efficacy of >60-80% in several such settings. Potential drawbacks include the requirement for 2 vaccine doses separated by 2-6 months, local and systemic reactogenicity that is significantly greater than observed with commonly used vaccines, and the inclusion of a strong adjuvant that has been minimally studied in clinical settings where it might be problematic, such as in people with autoimmune diseases. Postmarketing studies are underway to address some of the drawbacks.

RESUMO

BACKGROUND: In this study, we aimed to determine influenza, pneumococcal, and herpes zoster (HZ) vaccination status, among patients aged 65 or above, and to determine their level of knowledge about these vaccines and the factors affecting the vaccination rates. METHODS: This was a cross-sectional descriptive study conducted through face-to-face interviews with patients who were admitted to Gemerek State Hospital Family Medicine Clinics. The questionnaire prepared by the researchers following the literature review was applied by researchers. RESULTS: The study included a total of 326 participants with a mean age of 71.59 ± 6.96 (min: 65, max: 96). Influenza, pneumococcal, and HZ vaccination rates were 21.8% (n = 71), 4.3% (n = 14), and 1.8% (n = 6), respectively. The odds ratio (OR) in the patients for whom influenza vaccination was recommended was calculated to be 15.25 compared to those for whom influenza vaccination was not recommended (95% CI 8.73-26.64, p < 0.001), OR in the patients for whom pneumococcal vaccination was recommended was calculated to be 257.5 compared to those for whom pneumococcal vaccination was not recommended (95% CI 50.75-1306.44, p < 0.001), and OR in the patients for whom HZ vaccination was recommended was calculated to be 126.0 compared to those for whom HZ vaccination was not recommended (95% CI 18.59-853.92, p < 0.001). CONCLUSIONS: The main findings of the present study are that the vaccination rate for all three vaccines is low, vaccination recommendation by a physician significantly increases vaccination rates, and the vaccination rate of patients, who have been informed by the physician about the vaccine, is higher.

RESUMO

In the case of reduced cellular immunity the previously dormant varicella zoster virus (VZV) causes the characteristic belt-shaped vesicular exanthema of herpes zoster. The initial clinical symptoms of herpes zoster are often non-specific and may lead to initial misdiagnosis. A common complication of herpes zoster is postherpetic neuralgia (PHN) but secondary hematogenic dissemination is only rarely observed. In addition to general factors, such as advanced age and female gender, inflammatory rheumatic diseases and their immunosuppressive treatment are important risk factors for the occurrence of herpes zoster. Antiviral therapy initiated in the first 72 h after the onset of exanthema reduces acute symptoms and the risk of complications. The subunit inactivated vaccine, which has been available since 2018, is highly effective and relatively well-tolerated but randomized controlled trials in patients with drug-induced immunosuppression for inflammatory rheumatic diseases are still pending.

RESUMO

The self-controlled tree-temporal scan statistic allows detection of potential vaccine- or drug-associated adverse events without prespecifying the specific events or postexposure risk intervals of concern. It thus opens a promising new avenue for safety studies. The method has been successfully used to evaluate the safety of 2 vaccines for adolescents and young adults, but its suitability to study vaccines for older adults had not been established. The present study applied the method to assess the safety of live attenuated herpes zoster vaccination during 2011-2017 in US adults aged ≥60 years, using claims data from Truven Health MarketScan Research Databases. Counts of International Classification of Diseases diagnosis codes recorded in emergency department or hospital settings were scanned for any statistically unusual clustering within a hierarchical tree structure of diagnoses and within 42 days after vaccination. Among 1.24 million vaccinations, 4 clusters were found: cellulitis on days 1-3, nonspecific erythematous condition on days 2-4, "other complications . . ." on days 1-3, and nonspecific allergy on days 1-6. These results are consistent with local injection-site reactions and other known, generally mild, vaccine-associated adverse events and a favorable safety profile. This method might be useful for assessing the safety of other vaccines for older adults.
