I just watched the latest current events discussion, including on the new vaccine.
Prof Streeck of hotspot study fame was on, and previously having warned not to take the successful development of a vaccine for granted, said there were grounds to be optimistic on this one, but not to get too carried away.
It is though very early days. It's not known whether the vaccine prevents infections or prevents illness. No information on who the vaccine benefits most. There aren't enough numbers yet to be sure of any side-effects, this will take time. Hopefully this won't be the only vaccine that might be successful against the virus. The conditions for preserving this vaccine are going to be difficult for developing countries with poor infrastructure.
The politicians are already organising the necessary facilities to administer the vaccine - or a different one if it yet proves problematic. Realistically it is not likely to be available until early next year, and then the priority will be medical staff, carers in old people's homes, followed by older citizens and those with pre-existing medical conditions.
Long-term planning to avoid lockdown after lockdown is needed, and we will have to live with the virus at least during next year and possibly the year after, but at least life should be somewhat more normal than it is now.
Prof Streeck is a great believer in vaccines and would be happy to have the jab. His overall position was optimism yes, but not euphoria.
