**Prior to Feb 2022, similar Russian claims existed but were less specific.**
In Oct 2018, Maj. Gen. Igor Kirillov (Russian Radiological, Chemical & Biological Defense Troops) stated the US was financing “renewed construction” of biological laboratories in Ukraine (and Azerbaijan/Uzbekistan) to build up “military-biological potential” under the guise of peaceful research. He also alleged US development of biological weapon delivery systems.
Russian MFA statements (e.g., Maria Zakharova, April 2018) and state media raised parallel concerns about Pentagon-funded “microbiological laboratories” and pathogen-related activities near Russia’s borders, including in Ukraine and Georgia (Lugar Center focus). These fit a longer pattern documented in BWC meetings (e.g., 2015) and EUvsDisinfo reports from 2020–2021.
The detailed post-invasion narrative (specific pathogen transport, “emergency clean-ups,” lists of agents like plague/anthrax) intensified after Feb 24, 2022. Pre-2022 claims were broader accusations of suspicious US-funded labs and pathogen work.
**Context**: The US Biological Threat Reduction Program has supported Ukrainian public-health labs since 2005 to consolidate and secure Soviet-era pathogen collections for surveillance and biosafety — not weapons development. Ukraine owns/operates them. No credible evidence supports bioweapons claims; they have been consistently rejected by the US, Ukraine, UN, and independent analyses.
