NHS England 'on track' for vaccinating Covid priority groups

The NHS is "firmly on track" to offer everyone in the top four priority groups in England a Covid vaccine by Monday, says the head of NHS England.

Sir Simon Stevens said it had been a "very encouraging start, and obviously there is much more to do".

The UK government's aim is to reach 15 million of the most vulnerable by mid-February - and 14 million have been vaccinated so far.
