I thank my hon. Friend for his kind words. We constantly ask ourselves that question and we constantly ask our interlocutors from the relevant neighbouring countries whether there is anything else that should be done or that we can do to help. For example, when I was in Uganda, I was able to ask its Prime Minister whether the country would be able to approve the use of the experimental vaccine through their procedures as quickly as possible. I am glad to report to the House that, following that intervention, it has now been approved for use within Uganda.
