    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:
    There are a number of limitations of our study. First, we did not measure neutralizing antibody against live SARS-CoV-2 but used a surrogate neutralization assay which has a high correlation with live virus neutralization titers [16]. We did not assess antibodies against variants such as Delta or Omicron, but expect antibody levels to be reduced against variants as reported in other studies [16, 17]. We did not assess T cell responses which could contribute to protection against severe disease and could be less affected by variants [18]. In conclusion, we identified weaker boosting and faster waning of antibodies against SARS- CoV-2 in recipients of CoronaVac compared to BNT162b2, and would expect this to correlate with lower levels of protection against symptomatic infection for CoronaVac. In individuals of any age or sex, BNT162b2 responses were stronger and more durable than responses to CoronaVac. The weaker and less durable responses following CoronaVac support earlier provision of third doses to persons who previously received two doses of this vaccine.

    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.
