The UKHSA Science Strategy outlines the scientific assets, capabilities and ambitions of UKHSA, and our plan to protect the nation’s health from current and future health threats. The Science Strategy shares our vision of how, through science, we will secure health and prosperity. It describes how we can develop our current scientific disciplines and infrastructures to meet the current and future health threats both nationally and globally. We are highlighting the wide range of our scientific work through a number of blogs including an A-Z to learn more about health security science and the diverse and multidisciplinary science taking place at UKHSA and a note by our Chief Scientific Officer.
