What we found

Supports. Gavi (published 2026-10-08) says vaccines against plague exist but none are currently widely available, and that existing killed-bacteria vaccines offer limited protection against pneumonic plague.[5]

Supports. A science.gov compilation (published 2026-10-20) states that no efficient plague vaccine is currently available and that there are no approved vaccines against Yersinia pestis.[2]

Supports. The Illinois Department of Public Health (2026-03-16) says a plague vaccine is not currently available for use in the United States, and AP (2024) says there is no plague vaccine available in the US.[1][3]

Supports. The Express (2026-10-05, unrated) reports there is no commercial vaccine available anywhere in the world for pneumonic plague, and that a 2025 Israeli candidate has not been tested on people and is not yet available.[6]

Context. Candidate vaccines in development (NIH project record, npj Vaccines review) are not licensed or approved, which is consistent with the claim that no publicly available vaccine exists.[4][7]
