Immunogenic recombinant Mayaro virus-like particles present natively assembled glycoprotein.
Article in NPJ vaccines, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 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
Virus-like particles (VLPs) are an established vaccine platform and can be strong immunogens capable of eliciting both humoral and cellular immune responses against a range of pathogens. Here, we show by cryo-electron microscopy that VLPs of Mayaro virus, which contain envelope glycoproteins E1-E2 and capsid, exhibit an architecture that closely resembles native virus. In contrast to monomeric and soluble envelope 2 (E2) glycoprotein, both VLPs as well as the adenovirus and modified vaccinia virus Ankara (MVA) vaccine platforms expressing the equivalent envelope glycoproteins E1-E2, and capsid induced highly neutralising antibodies after immunisation. The levels of neutralising antibodies elicited by the viral-vectored vaccines of structural proteins and VLPs increased significantly upon boosting. Immunisation of Mayaro virus VLPs in mice with or without an adjuvant (poly:IC) yielded similar levels of neutralising antibodies suggesting that the VLPs may be used for immunisation without the need for an adjuvant. A single or two doses of non-adjuvanted 5 µg of MAYV VLP vaccination provided significant protection against viremia and MAYV-induced foot swelling in the C57BL/6 mouse challenge model. MAYV VLPs represent a non-infectious vaccine candidate, which may constitute a complementary option for future immunisation strategies against this important emerging alphavirus.
