Efficacy of modified-vaccinia Ankara vaccine as pre- and post-exposure prophylaxis against monkeypox sexual transmission in non-human primate model.

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 monkeypox virus (MPXV) outbreak of 2022 caused a human disease with unusual epidemiological and clinical features, notably an increase in human-to-human transmission through sexual contact, predominantly among men who have sex with men (MSM). This evolution underscores the need to reassess prevention and control strategies in the context of a sexually transmitted disease. Here, we show that rectal challenge of male cynomolgus macaques with a 2022 clade IIb MPXV isolate mimics sexual transmission, leading to rectal infection, with systemic and male genital tract dissemination and seminal fluid shedding. Vaccination with modified-vaccinia Ankara (MVA) protected the macaques from subsequent rectal MPXV challenge. However, MVA failed to prevent the disease when administered four days post-exposure to MPXV. These findings have a critical impact on outbreak management and highlight the importance of reevaluating MVA post-exposure prophylaxis protocols.
