Russia's EnteroMix and China's approval rumour: what's true, what isn't
Multiple media outlets reported in early May 2026 that China is preparing to approve Russia's experimental cancer vaccine EnteroMix, but the claim sits on top of a stack of public confusion — there are three distinct Russian cancer-vaccine programmes (EnteroMix, a separate personalized mRNA vaccine being developed by the National Medical Research Radiological Center and Gamaleya Center, and the Federal Medical and Biological Agency's FMBA colorectal-cancer vaccine that head Veronika Skvortsova said on TASS in September 2025 was 'ready for clinical use'); EnteroMix specifically is an oncolytic virotherapy using four live replication-competent enteroviruses (Coxsackievirus A21, Echovirus 7, Enterovirus B75 and a Sabin-derived PV-Russo poliovirus modification) administered intravenously — not an mRNA vaccine despite widespread mislabelling — and it remains in Phase I human clinical trials that began with 48 volunteers in June 2025 and are scheduled to run until October 2026, with no peer-reviewed publications, no listing in ClinicalTrials.gov or other international registries, no public release of full viral genome sequences as required under WHO Global Polio Eradication Initiative protocols, and no official public confirmation of approval or even formal evaluation from China's National Medical Products Administration.
