    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:
    This interim report has some limitations: small size of the trial, the short period of follow-up at this time point, and the participants’ young age and good health status. We were not able to assess the durability of the immune responses after Day 57 in this interim report. However, participants will be followed up for 6 months after the second vaccination with scheduled blood collections throughout that period to evaluate the humoral immunologic responses. Although the level of immunity needed to protect from COVID-19 remains unknown, NIBSC 20/130 standard serum was tested in terms of wild-type SARS-CoV-2 neutralizing antibody titer for the development and evaluation of serological assays for the detection of antibodies against SARS-CoV-2, as a positive control. These safety and immunogenicity findings support further advancement of the MVC-COV1901 vaccine to subsequent clinical trials. Of the three doses evaluated, both the MD and HD elicited high neutralizing antibody responses with all participants seroconverted after second vaccination. Further phase 2 trial with 3700 participants (including the populations at greatest risk for serious Covid-19 such as those with chronic medical diseases and older adults) is on-going (ClinicalTrials.gov number, NCT04695652)

    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.
