Millions more coronavirus vaccinations will reportedly reach centres in days including two million Pfizer jabs originally held back for second doses as pressure mounts on the Government to speed things up.
Boris Johnson has assured the nation that every aspect of the programme - from the Government's side - is "working flat out", with a quarter of over-80s having already had a jab.
But industry watchdogs are questioning why the process is proving much slower than first predicted, with fingers being pointed at No10 and the pharmaceutical suppliers.
More than four million doses of the Pfizer-Biotech vaccine have been delivered and passed checks by the MHRA, according to The Times.
