The vaccine rollout was plunged into its first real crisis last night as the NHS revealed a major four-week fall in supply. The source revealed that this included the need to re-test a large batch of the vaccine, although they did not specify from which manufactuer. Almost half of all UK adults have now received a vaccine, with the focus set to shift to second shots from next month. Health officials stressed the vaccine rollout ‘relies on a biological process which doesn’t always go smoothly’ with any blip potentially destroying a batch containing a million doses. Meanwhile, rising numbers of patients needing their second dose at 12 weeks will reduce how many can be offered a first vaccine.
