The Department of Health and Human Services, specifically the Office of Assistant Secretary for Preparedness and Response (BARDA), is seeking to procure additional doses of the JYNNEOS™ vaccine for the Strategic National Stockpile in response to the ongoing monkeypox outbreak. The procurement aims to rapidly secure 11 million doses of the vaccine by utilizing existing bulk drug substance and to enhance manufacturing capacity through technology transfer to contract manufacturing organizations. The JYNNEOS™ vaccine is critical as it is the only licensed vaccine for both smallpox and monkeypox, making it essential for public health preparedness. Interested parties can contact Yifan Yang at yifan.yang@hhs.gov, with the total estimated value of the contract modification being $992,400,000.
