Covid-19: Vaccine rollout widens as hospital pressure rises Published GPs in England are receiving doses of the Oxford Covid jab as medics warn about overstretched hospitals. The rollout of the Oxford vaccine is part of the NHS's biggest-ever effort and aims to offer jabs to 13 million by mid-February - including all over-80s. But Health Secretary Matt Hancock admitted vaccine supply was a "rate-limiting" factor. Birmingham's NHS said there are enough supplies with more to come as politicians warned doses may run out. Some hospitals in England are at risk of becoming Covid-only sites, with rising admissions for the virus forcing trusts to cut back on other services.
