Introduction The global coronavirus disease 2019 (COVID-19) pandemic necessitated urgent vaccine development, raising concerns about potential adverse events (AEs). Methods In this prospective cohort study, conducted from February 2021 to December 2022, all individuals across Iran who received any COVID-19 dose and reported were investigated. Our aim was evaluate these AEs based on the types, patients’ age types of AES, provide a comprehensive analysis. Results Iran, 155 million doses administered, with Covilo (Sinopharm) being most commonly administered (80.35%). Adverse predominantly affected aged 40-70 (45%). A total 86,275 recorded, 92.7% classified as non-serious 6 299 (7.3%) serious among cases, 279 confirmed be vaccine-related, 46 resulting in fatalities 233 requiring hospitalizations. incidence 0.41 per 10,000 doses. Serious more frequently associated Sputnik V Vaxzevria (AstraZeneca), 0.73 0.64 cases injections, respectively. Coagulation thrombosis disorders common (29%), followed by neurological (24.7%) cardiovascular (15.8%). Discussion conclusion, vaccination primarily mild transient, while remained exceptionally rare.

To analyses real-world safety data of mRNA COVID-19 vaccines within the European Economic Area (EEA), using Individual Case Safety Reports (ICSR), and to evaluate variability in profiles between different vaccine versions. We utilized EudraVigilance from 1 January 2020, 31 December 2023, focusing on Moderna (Spikevax) Pfizer/BioNTech (Comirnaty) against COVID-19. performed descriptive statistics, co-occurrence analysis, correspondence analysis identify patterns clusters adverse events following immunization (AEFI). retrieved 993,199 ICSR (Moderna: 394,484; Pfizer: 605,794), with most reports related women patients (69%) non-healthcare professionals (65%). A total 10,804 distinct AEFI terms were described across ICSR, a cumulative occurrence frequency 3,558,219 1,555,638; 2,031,828). The prominent serious included headache, fatigue, pyrexia, myalgia, arthralgia, malaise, nausea, chills, which frequently co-occurred vaccination failure. Specific like fever, injection site pain, inflammation, warmth more often linked Moderna, while Pfizer was commonly associated failure, menstrual disorders (heavy bleeding dysmenorrhea), hypoesthesia. In older adults, confusional states, cerebrovascular accidents, myocardial infarctions, myocarditis pericarditis noted younger males. Although rare, systemic AEFI, anaphylactic reactions, identified but require further causality evaluation. overall for mass is supported, continuous pharmacovigilance remains essential. Identified particularly ones, although rare potentially influenced by other underlying causes, underscore need monitoring epidemiological investigations explore potential causal relationships.

Introduction The emergence of SARS-CoV-2 variants concern (VOCs), particularly Omicron, has challenged the efficacy initial COVID-19 vaccination strategies. Booster immunizations, especially with mRNA vaccines, were introduced to enhance and prolong immune protection. However, underlying mechanisms humoral cellular immunity induced by homologous versus heterologous regimens remain incompletely understood. This study aimed elucidate responses, including B cell, plasmacytoid dendritic cell (pDC), T activation, following booster vaccination. Methods In a longitudinal cohort study, 136 individuals received three different regimens: mRNA, vector-mRNA-mRNA, or vector-vector-mRNA vaccinations. Serum peripheral blood mononuclear cells (PBMCs) collected at multiple time points up 64 weeks after Anti-SARS-CoV-2 IgG titers neutralization capacity against wildtype virus Omicron variant measured using ELISA cPass assays. Cellular was assessed IFN-γ release assays, flow cytometry employed analyze pDC frequencies, viability, activation markers. Functional pDC-mediated evaluated in mixed lymphocyte cultures. Results stabilized high anti-SARS-CoV-2 neutralizing activity across all regimens, group showing highest antibody capacity. Peripheral frequencies markers (MHC class I/II, CD86) significantly upregulated post-booster. pDCs demonstrated enhanced antigen-presenting promoted SARS-CoV-2-specific responses vitro . Despite differences between breakthrough infection rates 25 post-booster comparable cohorts, suggesting compensatory via immunity. Discussion Our findings highlight pivotal role sustaining effective While induce superior robust may balance protection levels infections. underscores importance integrated potential for optimized strategies pDC-targeted vaccine designs long-term emerging variants.

Overall, 2,541 BA.2, comprising 1,060 asymptomatic, 1,287 mild, 194 moderate infections, enrolled. The percentage infections was higher aged ≥ 60 years than those < 18 18–59 years. median hospitalization duration 17 days. Among the patients, 43.52% had a clear history close contact. vaccination rate 87.92%, asymptomatic vaccinated unvaccinated patients. Moreover, underlying diseases, including hypertension diabetes mellitus, more without diseases. most common manifestations fever, dry cough, sore throat. albumin-to-globulin (A/G) ratio lymphocyte count decreased cases mild while procalcitonin, erythrocyte sedimentation rate, interleukin-6, D-dimer, C4 levels increased.
