The Centers for Disease Control and Prevention (CDC) intends to award, on a sole source basis, a contract to University of Washington, Children's Hospital & Regional Medical Center, 4800 Sand Point Way, NE, Mailstop B-5520, Seattle, WA 98105. The purpose of the contract is to obtain data on the incidents of rotavirus in children < 5 years of age and the vaccination rate associated with those incidents. Justification for other than full and open competition is considered due to the fact that only Seattle Children's Hospital had sufficient number of rotavirus cases to perform the described activity. In 2008, no other sites had identified rotavirus cases besides the proposed vendor. Identifying rotavirus cases-patients during the current 2009 rotavirus season is crucial to estimate the effectiveness of the vaccine. Note 22 applies herein. The statutory authority permitting other-than-full-and-open competition is 41 U.S.C., 253(c)(1): FAR 6.302-1. Only one responsible source and no other services will satisfy agency requirements. Interested persons may identify their interest and capability to respond to the requirement. This notice is not a request for competitive proposals. A determination by the Government not to compete this proposed contract will be based on responses to this notice and is solely within the discretion of the government. Information received will be considered solely for informational purposes. This procurement is not set-aside for small business.
