NHS leaders have issued urgent pleas to the public for them to get their flu jabs and help the health service cope with a crippling “flu-nami”, which last week led to hospitals in England treating record numbers of seriously ill patients with flu. But the biggest pharmacy chains have no bookable appointments available in many of their city centre branches amid dwindling stocks of the flu vaccine. The shortages were revealed as resident doctors in England began five days of strike action after rejecting the government’s latest offer to resolve the long-running dispute over pay and jobs. Older people; those with long-term health conditions; pregnant women; and children are eligible for the flu jab on the NHS.
