The "enhanced" vaccine is expected to significantly boost flu jab effectiveness by improving the body's response to it.
Whether it's through a nasal spray or a shot, the Centers for Disease Control is advising people to get vaccinated against the flu this year.
Autumn is almost upon us, and with that comes a new round of the flu.
The vaccine, available for the first time this year in the United Kingdom 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. Furthermore, in hospital departments where patients are most at risk of flu, they have said it may be appropriate for those who choose not to be vaccinated to be redeployed to other areas.
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.
The strain of H3N2 usually results in a more severe flu season, and it's not clear what to expect this year. She urged people to get their flu shots by Halloween so the vaccine has time to build their body's immunity.
The vaccine will eventually be offered to all primary school-aged children.
PHE is in particular encouraging pregnant women; no matter how many weeks along they are, to get their vaccine from their GP, pharmacist or midwife this winter to protect them and their baby.
He says this year there is a new recommendation for egg-based flu vaccines.
The province's chief medical officer of health said we're about a month away from flu vaccines becoming available, and it's important to get immunized early.
Children aged between two and 10, pregnant women, carers and those with long-term health conditions like asthma are also eligible to receive the free flu jab. "We know this year that staff will continue to do a fantastic job to "Help us Help You" and minimise the spread of flu and help those who are most vulnerable to the virus".
Those eligible are encouraged to get their free vaccine from their GP or pharmacy before the end of November to protect themselves and their families before the peak flu season.
Dr Julie Yates, lead consultant in screening and immunisation for PHE, said: "Our figures show flu is not to be underestimated - every winter the virus makes hundreds of people seriously ill in the South West".
Basic hygiene will help prevent the spread of flu - including covering the mouth and nose when coughing or sneezing, washing hands with soap and water and throwing used tissues straight in the bin.
