Association Between Varicella Vaccination Status and Self-Reported Contact History Among Confirmed Varicella Cases in Chaoyang District, Beijing, 2017-2025.

Cao Yang Y, Wang Hao H, Zhao Ziwei Z, Li Zhen Z et al.

Objectives: To investigate associations between varicella vaccination and self-reported contact history with varicella or herpes zoster among clinically diagnosed varicella cases in Chaoyang District, Beijing, China. Methods: A retrospective observational study was conducted among 4441 clinically diagnosed varicella cases reported from 2017 to 2025. Multivariable logistic regression examined associations between vaccination status, number of doses, time since vaccination, and reported contact history with varicella and/or herpes zoster, adjusting for age, sex, and year of diagnosis. Results: Vaccinated cases had significantly higher odds of reporting contact with varicella or zoster compared with unvaccinated cases (OR = 1.34, 95% CI: 1.14-1.58). Both 1-dose and 2-dose recipients showed similar associations. A gradient of increasing odds was observed with longer time since vaccination, reaching OR = 3.17 (95% CI: 1.39-7.22) for 10 or more years since last dose. Associations were primarily driven by reported varicella contact rather than herpes zoster contact. Sensitivity analysis confirmed robustness of findings. Conclusions: Varicella vaccination was positively associated with reporting an identifiable exposure source. Vaccination status may influence completeness of exposure ascertainment in varicella surveillance and should be considered when interpreting contact tracing data.

[Evaluation of varicella vaccine effectiveness among children aged 1-14 years in Weifang City: a case-control study].

Wang Y Y YY, Peng P P, Tang Y J YJ, Wei J J et al.

Based on the reports from the Chinese Disease Prevention and Control Information System, 177 varicella cases among children aged 1 to 14 in Weifang City from 2022 to 2024 were selected as the case group. Through the Weifang Immunization Planning Information Platform, 708 healthy children were individually matched at a 1∶4 ratio by age, sex, and town/street and included as controls. A conditional multivariable logistic regression model was used to estimate the vaccine effectiveness (VE) of the varicella vaccine, while restricted cubic splines (RCS) were applied to analyze the dynamic changes in VE after the last dose. Results showed that the overall VE was 80.72% (95%CI: 69.16%-87.95%), with two-dose vaccination providing significantly higher protection (91.63%) than one dose (50.96%). The VE after the last dose exhibited an initial increase followed by a decline over time. In conclusion, the varicella vaccine demonstrates strong effectiveness against varicella; therefore, a two-dose vaccination strategy is recommended and should be incorporated into routine immunization programs.

Site-Specific Glycosylation Profiling of Protein Subunit and Inactivated Virus Vaccines.

Goecker Zachary C ZC, Burke Meghan C MC, Liu Yi Y, Mirokhin Yuri A YA et al.

Background/Objectives: Glycosylation can affect vaccine antigen structure and function, making site-specific glycan characterization relevant to antigen quality and comparability. However, quantitative approaches for comparing glycan microheterogeneity remain limited. This study evaluated the utility of the glycopeptide abundance distribution spectra framework for measuring similarity among site-specific glycosylation profiles in vaccines and antigen reference reagents across manufacturing conditions. Methods: Intact N-linked glycopeptides were characterized by nanoflow liquid chromatography-tandem mass spectrometry with stepped-energy fragmentation. Products included monovalent and quadrivalent influenza antigens produced in embryonated eggs, Madin-Darby canine kidney cells, or Spodoptera frugiperda cells, together with a SARS-CoV-2 spike vaccine produced in Spodoptera frugiperda cells and a Chinese hamster ovary cell-produced varicella-zoster virus glycoprotein E vaccine. Site-specific glycan distributions were represented as distribution spectra and compared using NIST MS Search software. Dot-product scores ranging from 0 to 999 quantified similarity. Results: Across measured glycosylation sites, distributions clustered into six recurrent classes. Similarity was high for replicate analyses, conserved influenza components across annual formulations, and matched components from different suppliers within the same production platform (similarity scores = 978, 961, and 960, respectively). Similarity was lower between sites within the same protein, between influenza strains, and between production sources (similarity scores = 554, 540, and 209, respectively). Among production-source comparisons, egg- and Madin-Darby canine kidney-derived profiles were most similar, and the overall ordering of glycosylation similarity was consistent with broad phylogenetic relatedness among production hosts. Conclusions: Distribution spectra-based similarity scoring of vaccine glycoproteins provides a quantitative, reusable approach for documenting site-specific glycosylation microheterogeneity. Using this method, we can conclude that production source is the dominant contributor to variation, whereas replicates, annual formulations, and suppliers within the same production platform are highly consistent.

Prognostic Factors and Clinical Characteristics of Varicella Zoster Virus Meningitis: Impact of Treatment Delay and Age-Related Differences in a Japanese Tertiary Hospital.

Tasaki Kenta K, Hara Makoto M, Nakajima Hideto H

Objectives: Varicella zoster virus (VZV) meningitis is a complication of herpes zoster that causes high rates of residual symptoms. However, prognostic factors and optimal management strategies remain unclear. This study investigated factors affecting functional outcomes, age-related differences, and the impact of prior oral antiviral therapy in VZV meningitis. Methods: This retrospective observational study enrolled patients admitted for aseptic meningitis between 2013 and 2022. The primary outcome was residual symptoms at discharge, defined as a ≥1-point increase in the modified Rankin Scale (mRS) from baseline. Multiple logistic regression identified independent risk factors. Results: Among 176 patients with aseptic meningitis, 60 (34.1%) had VZV meningitis. Patients with VZV meningitis had higher rates of residual symptoms (43.3% vs. 12.9%, p < 0.001). Independent predictors of residual symptoms included delayed intravenous acyclovir initiation (odds ratio [OR] = 1.303, 95% confidence interval [CI] = 1.060-1.601, p = 0.012), corresponding to a 30.3% increase in the odds of residual symptoms for each additional day before treatment initiation, and pre-onset mRS (OR = 2.352, 95% CI = 1.056-5.237, p = 0.036). Patients ≥ 50 years old displayed lower rates of headache (75.0% vs. 96.9%, p = 0.020), neck stiffness (25.0% vs. 62.5%, p = 0.005), and CSF pleocytosis (56/μL vs. 142/μL, p = 0.023). Prior oral antiviral therapy was not associated with a rate of residual symptoms (p = 0.795). Conclusions: Delayed initiation of intravenous acyclovir was independently associated with residual symptoms at discharge, whereas older patients often presented with atypical clinical features, requiring heightened clinical suspicion. Given the lack of observed benefit associated with prior oral antiviral therapy, prompt initiation of intravenous acyclovir should be considered when VZV meningitis is suspected.

Real-World Safety of Concurrent Measles-Mumps-Rubella and Varicella Vaccination in Korean Infants: A Multicenter Self-Controlled Case Series Study.

Choi Sujin S, Ahn Bin B, Lee Yeonjoo Y, Kim Gwanglok G et al.

Measles, mumps, rubella (MMR) and varicella vaccines are often co-administered to optimize coverage, yet safety concerns regarding febrile convulsions persist. In South Korea, MMR and varicella vaccines are administered as separate injections during a single visit (MMR + V). This study evaluated the real-world safety of concurrent MMR + V vaccination, focusing on the domestically implemented MAV/06 and Oka-derived strains. We conducted a multicenter self-controlled case series (SCCS) study of children aged 12-23 months who received MMR + V and hepatitis A vaccine (HAV) between 2015 and 2024. Using electronic health records, we identified predefined adverse events (AEs), including fever and healthcare visits. Adjusted relative risks (aRRs) were estimated using conditional Poisson regression. Among 3035 children (52.3% male; median age, 12 months), 71.7% received the MAV/06 varicella strain. A distinct peak in AEs occurred 7-13 days after MMR + V administration, with fever showing the greatest increase (aRR, 4.27; 95% CI, 2.76-6.60). The risks of total sick visits (aRR, 2.15; 95% CI, 1.70-2.71) and acute care visits (aRR, 2.13; 95% CI, 1.46-3.10) were similarly confined to this interval and returned to baseline thereafter. Febrile convulsions were uncommon (aRR, 5.37; 95% CI, 1.20-24.01). No excess risks were observed during the HAV or overlap periods, and no synergistic effects of intensive multi-vaccine administration were detected. Concurrent administration of MMR and varicella vaccines in Korean infants-predominantly using the MAV/06 strain-was associated only with expected, transient increases in fever during days 7-13 postvaccination. No serious or sustained safety signals were identified, supporting the continued use of Korea's separate-injection MMR + V strategy.

Knowledge, Awareness, Attitudes, Acceptance, and Uptake of the Herpes Zoster Vaccine in Saudi Arabia: A Scoping Review.

Abusalih Howeida H

Background: Herpes zoster (HZ), commonly known as shingles, and post-herpetic neuralgia (PHN) represent growing public health concerns, particularly among older adults. Despite the established efficacy of the herpes zoster vaccine (HZV), global uptake remains suboptimal. Objectives: This scoping review maps evidence from Saudi Arabia evaluating the baseline knowledge, awareness, attitudes, acceptance, hesitancy, and clinical uptake of the HZV among general adults, high-risk populations, and healthcare workers (HCWs). Methods: The JBI and PRISMA-ScR methodological frameworks were strictly adhered to during mapping. Eligible sources included peer-reviewed, observational cross-sectional studies conducted in Saudi Arabia and published in English between 2022 and 2026. The search was conducted across PubMed, Scopus, Web of Science, and Google Scholar. Data were systematically extracted and charted using a standardized digital piloting framework to capture study characteristics (author, year, and region), sample sizes, target populations, knowledge percentages, actual vaccine uptake rates, and self-reported barriers. Results: Out of 25 retrieved records, 19 unique primary studies were mapped. Public knowledge of HZ complications and vaccine eligibility criteria was consistently low to moderate, falling below 50% across most cohorts. Conversely, while verbal willingness to receive the vaccine was highly favorable (ranging from 60% to 75%), a profound "intention-behavior gap" was observed, with actual clinical uptake being below 10%. Key barriers included a lack of public health campaigns, safety concerns regarding reactogenicity, online misinformation, and a lack of proactive provider communication. For HCWs, barriers included unclear local guidelines and a lack of workplace mandates. Ultimately, a proactive physician recommendation was identified as the single most powerful clinical facilitator, increasing vaccine acceptance by over 80% across all cohorts. Conclusions: While the shingles vaccine is now distributed completely free across Saudi Arabia, high public willingness has not translated into actual vaccination rates (10%) due to low public awareness of disease severity. Free vaccine availability alone is insufficient; primary care systems must shift from a passive delivery model to an active, provider-driven framework to successfully close this gap.
