Flu cases are rising sharply across England, prompting the NHS to issue an urgent call for millions to get vaccinated before winter peaks. In this blog, Dr Richard Dune examines the “flu jab SOS” campaign, which opens 2.4 million appointments to protect vulnerable groups and ease seasonal pressures on hospitals. He explores how early vaccination, data-driven planning, and cross-sector collaboration can strengthen winter resilience across health and social care. The message is clear: prevention, preparation, and partnership remain vital to protecting both patients and the NHS this winter.
