The noble Baroness is right to highlight the benefits that the vaccine has brought. Previously, an outbreak of Ebola was passed on to four people; now, it is just one, following the vaccine. We should be very proud that UK aid played a part in developing that vaccine. We are working closely with the vaccine manufacturer and the Chief Medical Officer in the Department of Health and Social Care to ensure that we have enough. We are monitoring the numbers of vaccine that would be needed, and we are investing in further research to ensure that we are prepared for another outbreak.
