    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).


    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    However, we also acknowledge the weaknesses of our study. Our data are generated by a volunteer citizen-science initiative delivered through an app, with the CSS cohort more likely to be of White Caucasian ethnicity and higher family socioeconomical status than the overall UK population 14. By virtue of UK government policy timing and age-tiered approach, our study was restricted to considering single-dose vaccination with BNT162b2 in CYP aged 12-17 years; our results may not apply to other vaccines or in younger age- groups. Our study was conducted with the prevailing SARS-CoV-2 variants Delta and Omicron; the impact of vaccination (both effectiveness and durability) and the profile of post-vaccination COVID-19 might differ with other variants. Indeed, the durability of vaccine protection against Omicron beyond 3 months in our cohort remains to be determined, due to insufficient data, noting here the ability to assess vaccination effectiveness in CYP naïve to SARS-CoV-2 is dwindling rapidly, given widespread infection in the community, particularly CYP. Vaccinated CYP were also much more likely to be tested for SARS-CoV-2 than unvaccinated CYP, for reasons that we are unable to determine. Our data do not allow determination of causal variants for CYP testing positive either post- or prior to vaccination: we can only infer likely variant based on population prevalences at time of testing. Vaccination can attenuate viral RNA shedding 29; this might result in the overestimation...

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
