The characterization of technical design of a virus-like structure (VLS) nanodelivery system as vaccine candidate against SARS-CoV-2 variants.

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
The constant mutation of SARS-CoV-2 has led to the continuous appearance of viral variants and their pandemics and has improved the development of vaccines with a broad spectrum of antigens to curb the spread of the virus. The work described here suggested a novel vaccine with a virus-like structure (VLS) composed of combined mRNA and protein that is capable of stimulating the immune system in a manner similar to that of viral infection. This VLS vaccine is characterized by its ability to specifically target dendritic cells and/or macrophages through S1 protein recognition of the DC-SIGN receptor in cells, which leads to direct mRNA delivery to these innate immune cells for activation of robust immunity with a broad spectrum of neutralizing antibodies and immune protective capacity against variants. Research on its composition characteristics and structural features has suggested its druggability. Compared with the current mRNA vaccine, the VLS vaccine was identified as having no cytotoxicity at its effective application dosage, while the results of safety observations in animals revealed fewer adverse reactions during immunization.
