The Centers for Disease Control and Prevention intends to award a sole source firm fixed price contract to Merck Sharp and Dohme LLC for storing and rotating pediatric vaccine doses in a national pediatric stockpile as part of the Vaccines for Children program. Merck is the only source capable of rotating its older stockpiled vaccines into operating inventory before expiration and replenishing them to maintain a viable stockpile. This notice is not a request for competitive proposals, but any firm believing it can fulfill the requirement may submit a written response with a capability statement. No budget amounts or performance location are specified in the description. The government will not pay for any information received, and interested firms must be registered in the System for Award Management.
