My Lords, it is great to see the data on the efficacy of vaccines against the delta variant, but we know that that might not always be the case in the future. The announcement from the Prime Minister that we will share 100 million of our excess vaccines is a welcome first step, but the G7 failed to achieve its 1 billion target, let alone the 11 billion that the WHO says is needed. Does my noble friend the Minister agree that variants present one of the greatest threats to the unlockdown here in the UK and that the pandemic is not over here unless it is over everywhere? What are the next steps to ensure that low-income countries are vaccinated as soon as possible? Given the success of our vaccine programme, will the UK take a leadership role in this, as we continue our G7 presidency?
