Vulnerable groups in Burnley are being advised to get their free flu jabs as soon as possible.
People with a long-standing health condition, the elderly, pregnant women, and parents of children aged two to four are being urged to get the vaccine from their GP.
Public Health England said older people, the very young, pregnant women and those with a health condition, particularly chronic respiratory conditions such as asthma, diabetes or heart disease, or those who have a weakened immune system are at particular risk from the more serious effects of flu.
Expectant mums are encouraged not to put off the injection as pregnancy naturally weakens the body’s immune system, increasing the risk of a mother and unborn baby becoming seriously ill.
Since 2013, two and three-year-olds have also been eligible for a flu vaccination by using a nasal spray, and this year the spray is also being offered to four-year-olds.
