The 2022 Mpox virus (MPXV) outbreak revitalized questions about immunity against MPXV and vaccinia-based vaccines (VAC-V), but studies are limited. We analyzed immunity against MPXV in individuals infected with MPXV or vaccinated with the licensed modified vaccinia Ankara (MVA) Bavarian Nordic or an experimental MVA-HIVB vaccine. The frequency of neutralizing antibody responders was higher among MPXV-infected individuals than MVA vaccinees.

Background: Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome has been considered as a childhood syndrome. Its etiopathogeny is unknown however, currently considered as auto-immune inflammatory disease. Recently, a few cases of adult-onset of PFAPA syndrome have been reported.

Background: Cyclophosphamide (CYC) is an inactive alkylating agent that transforms the alkyl radicals into other molecules and is used in combination with systemic corticosteroids in the treatment of many childhood rheumatic diseases, such as systemic lupus erythematosus (SLE), and ANCA-associated vasculitis (AAV). In recent years, rituximab (RTX), a B-cell-targeting anti-CD20 monoclonal antibody, has emerged as a new alternative treatment modality over CYC for induction therapy of childhood-onset rheumatic diseases. Clinicians adopt different practices for using CYC particularly in relation to indications, posology, pre-treatment laboratory work-up, post-treatment follow-up, and screening pre- and post-treatment vaccination status.

We explored adolescent viewpoints on vaccines and hesitancy using an anonymized, validated, self-completed electronic questionnaire amongst state-school Year 12-13 adolescents in London, UK. As the response rate was low (Cohort 1; = 112/486, 23.0%), we repeated the survey with incoming students (cohort 2, = 256/275; 93%).

Age is among the strongest risk factors for severe outcomes from SARS-CoV-2 infection. Here we describe upper respiratory tract (URT) and peripheral blood transcriptomes of 202 participants (age range of 1 week to 83 years), including 137 non-hospitalized individuals with mild SARS-CoV-2 infection and 65 healthy individuals. Among healthy children and adolescents, younger age is associated with higher URT expression of innate and adaptive immune pathways.
