Such information was disseminated in social networks, in particular, on telegram channels broadcasting pro-Kremlin rhetoric. Reports say that Ukraine is collecting DNA samples from Ukrainian Armed Forces fighters to create biological weapons in American laboratories. The authors of the messages add that in this way the United States is trying to destroy all the Slavs. In support of this information, the authors refer to the statement of US Air Force  Captain (ret.) Stanislav Krapyvnyk. It is not true.

The fact-checkers of the VoxCheck project drew attention to this case and determined that there is no official confirmation of how Ukraine is going to produce or has already produced biological weapons. Even at the beginning of the large-scale invasion, Russian statements about biological weapons were refuted in the United States, and later in the UN.

In 2005, the Department of Health signed a cooperation agreement with the United States on the Biothreat Reduction Program. Therefore, Ukrainian laboratories are working to detect and reduce the threat of dangerous pathogens.

In addition, the fact-checkers found out that Stanislav Krapyvnyk himself was born in Luhansk and now lives in Russia. No information about him was found in the foreign segment of social networks. Information about officer service in the US Army can only be found in the Russian segment.
