Another 489,934 coronavirus jabs have been given in the UK - as the vaccination total rises to 8,859,372.
Government data up to January 29 shows of the 8,859,372 jabs given in the UK so far, 8,378,940 were first doses - a rise of 487,756 on the previous day's figures.
Some 480,432 were second doses, an increase of 2,178 on figures released the previous day.
It comes as Professor Anthony Harnden, the deputy chairman of the Joint Committee on Vaccination and Immunisation (JCVI), said preliminary research suggested the first dose of the vaccine is helping to protect young adults and over-80s.
The seven-day rolling average of first doses given in the UK is now 359,656.
