This winter's flu vaccine has been updated to protect against last year's Super-K strain, with the first doses being given to schoolchildren and pregnant women.
Flu hit early last winter with a new mutated version of the virus circulating - a seasonal influenza called subclade K or Super-K.
School children are being prioritised - and like pregnant women can get the jab from Tuesday - because they can catch and spread flu easily. Protecting them also helps others, including baby brothers or sisters and grandparents.
Other eligible groups, including people aged 65 and over, can get a free NHS flu shot from October and should receive an invite by phone or post.
Super-K flu
Last winter's flu season was unexpected, beginning more than a month earlier than usual, with the Super-K strain.
Super flu is not a medical term, and it does not mean the virus has become harder to treat, just that people are yet to build up immunity against it.
Flu vaccines are updated annually to ensure they are a good match for the type of flu circulating. Influenza viruses constantly mutate and experts have to predict these changes ahead of time.
This year's vaccine has had a few tweaks, including one to better match subclade K.
It is not clear when flu will hit this year, and whether it will be a bad season. But experts often look to southern hemisphere countries, like Australia and New Zealand, to gain a better understanding of how the UK could be affected.
Their flu season peaks in July or August. Australia has had fewer cases than last year, but New Zealand has seen high numbers.
Dr Amanda Doyle from NHS England said it was best to be cautious.
"Last year's flu season came early and was made worse by a new variant, which had a major impact for patients and put enormous pressure on urgent and emergency care services across the country," she said.
"With the NHS experiencing its busiest summer on record, staff have started preparing for this winter earlier than ever - and with services already under significant pressure, it is vital that everyone offered the vaccine comes forward."
Who can get it, and when?
Everyone is at risk of catching flu. It does not matter how fit and healthy you are, or your age.
Dr Doyle said: "Flu can really knock you for six, and for some children and pregnant women it can mean becoming seriously ill or ending up in hospital."
The vaccine cannot give you flu. Instead, it helps your body know how to fight the virus.
Children, from the age of two upwards, get a nasal spray version, while adults have an injection. A single dose is all that is needed to offer protection ahead of winter.
High Street pharmacies are offering NHS flu vaccines, along with GPs and schools. People who do not qualify for a free jab can pay about £10 to £20 for one.
School children and pregnant women can get a free NHS flu vaccine from September onwards. You can get a free one from October if you:
- are a child aged two or older who has not started school yet
- are aged 65 or over
- have certain long-term health conditions
- live in a care home
- are the main carer for an older or disabled person, or receive a carer's allowance
- live with someone who has a weakened immune system
- are experiencing homelessness or staying in a homeless hostel or night shelter
