    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Our study has several limitations, including the small number of subjects and the lack of comprehensive epitope mapping beyond the immunodominant response we identified. There are several questions that we did not address that will be useful topics for future studies, including the extent of clonal overlap between the blood and lymph node CD4+ T cell compartments, and the transcriptional profiles of the lymph node TFH response over the long period of clonal stability. In conclusion, we find that mRNA vaccine technology has an exceptional ability to induce high-frequency antigen-specific B cell (Turner et al., 2021) and antigen-specific CD4+ TFH cell responses in the human lymph node following prime-boost administration. These characteristics underlie the development of high titer neutralizing antibodies and protection from infection in vaccinated individuals. The selective enhancement of lymph node TFH responses induced by vaccine regimens represents a broad strategy for improving future vaccines.

    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.
