During the last year, we have been working hard to continue our research safely whenever, and however, current regulations allow. We are not currently testing participants due to the present restrictions, however once we are able to restart testing, we will be contacting all families who have expressed an interest in returning to CALM. We will update our website with further information in due course. Please follow this link for more information: http://calm.mrc-cbu.cam.ac.uk/covid-19-adapted-protocol/
