Broad protection and respiratory immunity of dual mRNA vaccination against SARS-CoV-2 variants.
Article in NPJ vaccines, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
While first-generation, spike (S)-based COVID-19 vaccines were effective against early SARS-CoV-2 strains, the rapid evolution of novel Omicron subvariants have substantially reduced vaccine efficacy. As such, broadly protective vaccines against SARS-CoV-2 are needed to prevent future viral emergence. In addition, it remains less clear whether peripheral immunization, especially with mRNA vaccines, elicits effective respiratory immunity. Our group has developed a nucleoside-modified mRNA vaccine expressing the nucleocapsid (N) protein of the ancestral SARS-CoV-2 virus and has tested its use in combination with the S-based mRNA vaccine (mRNA-S). In this study, we examined efficacy of mRNA-N alone or in combination with mRNA-S (mRNA-S+N) against more immune evasive Omicron variants in hamsters. Our data show that mRNA-N alone induces a modest but significant protection against BA.5 and that dual mRNA-S+N vaccination confers complete protection against both BA.5 and BQ.1, preventing detection of virus in the hamster lungs. Analysis of respiratory immune response in mice shows that intramuscular mRNA-S+N immunization effectively induces respiratory S- and N-specific T cell responses in the lungs and in bronchoalveolar lavage (BAL), as well as antigen-specific binding IgG in BAL. Together, our data further support mRNA-S+N as a potential pan-COVID-19 vaccine for broad protection against current and emerging SARS-CoV-2 variants.
