Description of Scope of Requirements: The UK Health Security Agency (UKHSA) is responsible for protecting every member of every community from the impact of infectious diseases, chemical, biological, radiological and nuclear incidents and other health threats.

We provide intellectual, scientific and operational leadership at national and local level, as well as on the global stage, to make the nation's health secure. Background: UKHSA is seeking to engage with the market to better understand supplier capability for the provision of lyophilisation (freeze-drying) services for X-ray irradiated pathogens to provide greater resilience and flexibility across use cases as part of UKHSA’s Pandemic Preparedness strategy.

UKHSA requires support in developing optimal formulations and lyophilisation processes to ensure that irradiated, inactivated pathogens can be safely stored, handled, and distributed for diagnostic use and pandemic preparedness. Lyophilisation is required to enhance the long-term stability and usability of these materials, supporting strategic resilience and response capabilities. Requirements: We need the supplier to have: • Ability to handle irradiated, inactive viral and bacterial material in liquid medium • Ability to develop and optimise lyophilisation protocols including assessment of different stabilisation matrices • Appropriate quality system in place (at least ISO 9001) to ensure consistency and traceability • Provide product quality control (QC) testing of final product, including thermal stability and absence of contaminants. • Overall aim is to lyophilise up to 20 pathogens over the next 4 years o Estimated vial volume for lyophilisation is 0.3mL – 2mL o Estimated batch size for lyophilisation is 6 – 100mL o Estimated number of batches per year is 5 Should you wish to respond to this Request for Information, please complete the response questionnaire which is found at the following link: https://atamis-1928--prospend.vf.force.com/apex/CS_Contra...
