People eligible for vaccinations can book their appointments from Wednesday, October 1.
The eligible groups include individuals aged 75 and over, care home residents, and adults and children aged six months and over with a weakened immune system.
Those aged over 65 or in a clinical risk group can also get vaccinated for flu.

The vaccination programme for flu began in September for pregnant women and children aged two to 16.
For the first time, two-and three-year-olds can now get vaccinated against flu at local pharmacies.
Dr Michele Legg, clinical lead for the NHS Hampshire and Isle of Wight vaccination programme, said: "As we prepare to enter the colder months, we know respiratory illnesses such as flu and Covid-19 become more common.
"Symptoms can range from feeling quite unpleasant for some people right up to hospitalisation for others, which is something we want to avoid.
"These vaccinations provide vital protection, helping to prevent serious illnesses and reduce hospital admissions during the busy winter months."
Many people will be invited directly via their GP practice.
But those eligible do not need to wait for an invitation and can book via the online national booking system, by calling 119, or via the NHS app.
