    Please note, not all rigor criteria are appropriate for all manuscripts.

    Table 1: Rigor

    EthicsIRB: The Investigational Review Board or Ethics Committee at each study site approved the protocol.
    Consent: Written informed consents were obtained from all healthy volunteers prior to the enrollment.
    Sex as a biological variableEligible participants were healthy men and women aged 18-65 years at the time of 1st vaccination for Phase-1/2 and Phase-2 studies.
    RandomizationStudies are prospective, open-label, randomized (phase-1/2) to assess best vaccine formulation based on safety, tolerability, reactogenicity and immunogenicity in Covid-19 RT-PCR and sero-negative subjects.
    Blindingnot detected.
    Power Analysisnot detected.

    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.
