Moderna mpox mRNA vaccine shows early promise in monkey study - Clinical Trials Arena
Moderna's mRNA vaccine for mpox shows higher efficacy than Bavarian Nordic's Jynneos in preventing severe disease and reducing virus levels in monkeys, according to a study published in Cell. The vaccine also reduced viral replication and lesion formation, potentially limiting spread. Moderna is currently conducting a Phase I/II trial in the UK, with data expected in mid-2025.

Mpox, caused by monkeypox virus (MPXV), re-emerged in 2024 with clade I strains spreading faster and being deadlier. A new study led by researchers from the United States Army Medical Research Institute of Infectious Diseases, the National Institutes of Health, Boston University, and Moderna, published in *Cell*, demonstrated that mRNA-based vaccines, like mRNA-1769, could be more effective than the modified vaccinia Ankara (MVA) vaccine in protecting against severe mpox disease in macaques. The mRNA-1769 vaccine, targeting four MPXV antigens, showed tenfold fewer lesions and reduced viral load compared to MVA, highlighting the potential of mRNA technology to combat MPXV-like viruses.
