Meanwhile the new Oxford-Astra Zeneca vaccines have reached our hospital sites today, and the first doses will be given on Monday.
It was reported that as many as a million doses of the cheaper vaccine could be made available every week.
The Royal Sussex County Hospital's chief nurse Carolyn Morrice previously said the introduction of the vaccination centre was "an incredible morale boost".
She said it was important for the hospital to seek ways to better protect its patients, as well as treat them.
"And actually it's taking a toll on us personally, where we are always, at the back of our minds, a little bit worried," she said. "Could we cause harm to our loved ones because we work in such a high-risk environment?"
