A new winter flu vaccine will be available to over 65s, while the nasal spray vaccine will be extended to cover an additional 650,000 children, Public Health England has said.

The vaccine, available for the first time this year in the UK for those aged 65 and over, could reduce GP consultations by 30,000, hospitalisations by over 2,000 and prevent over 700 hospital deaths from flu in England, alleviating some of the health burden that seasonal flu places on the population, workplaces and the NHS.

The newly available ‘adjuvanted’ vaccine is expected to significantly boost effectiveness by improving the body’s immune response to the vaccine. This is important because typically, older adults’ bodies do not respond as well to the flu vaccine due to their naturally weaker immune systems. Older adults are also more likely to suffer complications from flu.

The broader flu vaccination programme will also be improved by offering all eligible adults under 65, including pregnant women and those with long-term health conditions, the ‘quadrivalent’ vaccine in injected form.

This protects against a total of four strains of flu; two strains of flu A and two strains of flu B.

Professor Paul Cosford, Medical Director at PHE, said: “Flu is potentially a very serious illness, and we know adults over 65 are more likely to catch and have complications from flu so have the most to gain from an improved vaccine. By introducing an enhanced flu vaccine for this age group they will be better protected as well as helping to reduce the spread of flu to those around them.

“Further protection will be gained by offering flu vaccine to more children this year and giving a vaccine that provides protection against 4 strains of flu to all eligible people under the age of 65. We encourage everyone who is eligible to get the flu vaccine from their general practice or pharmacy before the end of November.”

The vaccination programme will also be improved by extending the nasal spray vaccine to primary school children in year 5 (650,000 extra children), meaning the vaccine will be offered to children in years reception, 1, 2, 3, 4 and 5. The programme will eventually roll out to all primary school children.

When this happens, evidence suggests that an additional 63,000 GP consultations could be prevented each year. Due to having typically poorer hand hygiene than adults, children tend to be ‘super-spreaders’ of flu, so protecting them is crucial for protecting the rest of the population.

Chief Medical Officer, Professor Dame Sally Davies said: “Getting the flu vaccine is the single best way to protect yourself against this potentially fatal illness, and this year the NHS is offering it to 24 million people across the country.

“In addition to this – a newly available vaccine that is more effective will be offered to over-65s. This could prevent hundreds of deaths and save thousands of GP and hospital hours – I strongly encourage everyone in vulnerable groups to get the life-saving vaccine as we head into winter.”

Professor Jane Cummings, Chief Nurse for England, said: “Faced with the worst flu season in a decade, NHS staff last winter did a remarkable job providing care for patients.

“This year, the public will be better protected from flu than ever before, with at-risk groups being offered the most effective vaccine available and every member of NHS staff expected to get their jab.”
