Similar fears last year saw flu vaccine eligibility expanded to all adults over 50 and children in Year 7. This year the plans are even bigger, with secondary school pupils up to Year 11 included in the roll-out.
From August 31, free flu jabs will also be offered to all children aged two and three , primary school pupils, people with certain health conditions, unpaid carers, pregnant women and frontline health and adult social care staff.
In total, officials expect the jab to be offered free to more than 35 million people. By comparison, a record 19 million seasonal flu jabs were administered in winter 2020.
