Thank you for your statement, Minister. I hope and pray that you are able to meet all your targets. Minister, are you content that we are administering every dose that we receive? There is widespread concern that the length of time between the two doses is far too great. Will you publish the JCVI advice that you have used to inform your decision to increase the time between the doses? Can you please outline how much protection is granted by a single dose of each of the available vaccines? The main barrier to quicker vaccination of the population is supply, so, Minister, are you able to update us on the progress being made on the approval of the other vaccine candidates, such as the one from Johnson & Johnson? Finally, Minister, we can't afford to waste this most precious resource. You have said that only 1 per cent of the vaccine has been wasted so far, but this amounts to thousands of doses, and thousands of people who could have been vaccinated have not received their first dose. So, Minister, what steps are you taking to reduce waste to around 0.1 per cent, rather than its current level? Diolch yn fawr.
