Might be speculation but:

Mass vaccine program potentially just months away for UK
A mass roll-out of a Covid-19 vaccine in Britain could be finished in as little as three months, the Times reports, citing government scientists.

Scientists working on the Oxford vaccine hope regulators approve it before the beginning of 2021, the newspaper says.

A full Covid-19 immunisation programme that would exclude children could be quicker than experts predicted, the Times says, adding that health officials estimate that every adult could receive a dose of the vaccine within six months.

The European Medicines Agency said on Thursday it had started reviewing data on AstraZeneca and Oxford University’s potential Covid-19 vaccine, in real time, the first of such moves aimed at speeding up any approval process in the region for a vaccine.

The news of the European review also raises chances of the British vaccine, which is seen as leading the race for a successful vaccine against Covid-19, becoming the first to be approved in Europe for the disease caused by the novel coronavirus that has killed more than a million people globally.

The Times report adds that plans under consideration by government include allowing a much wider group of healthcare staff to administer the vaccine, setting up drive-through vaccination centres and recruiting armed forces’ help.
