BackgroundRisk factors for infection and, therefore, antibody positivity rates will be different in children compared to adults. We aim to estimate national and regional prevalence of SARS-CoV-2 antibodies in primary (4-11-year-olds) and secondary (11-15-year-olds) school children between 10 November and 10 December 2021.MethodsCross-sectional surveillance in England using two stage sampling, firstly stratifying into regions and selecting local authorities, then selecting schools according to a stratified sample within selected local authorities. Participants were sampled using a novel oral fluid validated assay for SARS-CoV-2 spike and nucleocapsid IgG antibodies.Results4,980 students from 117 state-funded schools (2,706 from 83 primary schools, 2,274 from 34 secondary schools) provided a valid sample. After weighting for age, sex and ethnicity, and adjusting for assay accuracy, the national prevalence of SARS-CoV-2 antibodies in primary school students, who were all unvaccinated, was 40.1% (95%CI; 37.3-43.0). Antibody prevalence increased with age (p<0.001) and were higher in urban than rural schools (p=0.01). In secondary school students, the adjusted, weighted national prevalence of SARS-CoV-2 antibodies was 82.4% (95%CI; 79.5-85.1); including 57.5% (95%CI; 53.9-61.1) in unvaccinated and 97.5% (95%CI; 96.1-98.5) in vaccinated students. Antibody prevalence increased with age (p<0.001), and was not significantly different in urban versus rural students (p=0.1).ConclusionsUsing a validated oral fluid assay, we estimated national and regional seroprevalence of SARS-CoV-2 antibodies in primary and secondary school students. In November 2021, 40% of primary school students and nearly all secondary school students in England had SARS-CoV2 antibodies through a combination of natural infection and vaccination.

Background and Objectives: Loss of social connections in the community is a common consequence of severe traumatic brain injury (TBI), resulting in reduced well-being and quality of life. M-ComConnect is an individualized multi-component community connection intervention with the key objectives of increasing social activity, developing social relationships, and supporting community participation following severe TBI. As part of the M-ComConnect approach, semi-structured initial interviews were conducted to develop a holistic understanding of each participant and their goal focus for the project. In this paper we describe how clinicians worked with participants to identify a desired community-based social activity in which to participate.Method: Transcripts of initial interviews between participant and clinician were analyzed using the phases of reflexive thematic analysis developed by Braun and Clarke. Participants were ten individuals aged between 24 and 75 with severe TBI. All were living in the community and reported reduced social connections since their TBI. The aim of the analysis was to evaluate the skills and strategies used by clinicians in their interactions with participants to derive goal focus for the program.Results: Thematic analysis of initial interview data revealed three main categories and fourteen sub-categories of clinical strategies. These were: (1) Humanizing (curiosity; demonstrating respect and empathy; providing compliments and affirmations; simple reflections; revealing aspects of self; and humor and laughter), (2) Empowering (emphasizing choice and control; highlighting strengths; identifying roadblocks and reframing to reveal opportunities; and collaborative problem solving), and (3) Focusing (making suggestions; identifying preferences; working with ideas; and negotiating). These strategies aligned with the program's relational approach and supported the core processes of the goal-focussing framework, namely understanding and connecting with you, building a relationship, and working together with you to find focus.Conclusion: The goal-focusing framework and clinical strategies outlined provide guidance for clinicians working with people with TBI in the community and is a promising way to engage clients when focusing on individualized social activity-based goals.
