Preventive effect of vaccination on long COVID in adolescents with SARS-CoV-2 infection.
Article in Vaccine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeIn adolescents (12-17 years), it is unknown whether COVID-19 vaccination reduces progression from COVID-19 to Long COVID (LC) beyond preventing SARS-CoV-2 infection. We assessed the effect of vaccination among SARS-CoV-2 infected adolescents. METHODS AND
resultsParticipants were recruited from over 60 US healthcare and community settings. The exposure was any COVID-19 vaccination 6 months prior to infection. The outcome was LC defined using the LC research index. Vaccinated (n = 724) and unvaccinated (n = 507) adolescents were matched on sex, infection date, and enrollment date. The risk of LC was 36 % lower (95 % CI, 17 %, 50 %) in vaccinated compared to unvaccinated participants.
conclusionsVaccination reduces the risk of LC. Given the profound impact LC can have on the health and well-being of adolescents and the limited availability of treatments during this developmental stage, this supports vaccination as a strategy for preventing LC by demonstrating an important secondary prevention effect.
