FLU jab patients have been urged not to be concerned if they haven’t yet received a letter about the vaccine.

NHS Lanarkshire insisted all documentation has been sent by first class post to those aged 60 to 64-years-old.

However, bosses said any letters caught up in the Christmas rush will not result in missed appointments, as the letters contain contact details to arrange a jab.

It comes as the health board reveals it has vaccinated around 14% more elderly people against the flu virus than last year.

Overall, staff have inoculated 230,370 people across 1,703 clinics so far - more than the entire programme last year.

It comes after the Glasgow Times launched its Give Our OAPs a Shot campaign in a bid to ensure the city’s most vulnerable people were protected.

Dr Mark Russell said “People in the 60 to 64 age group are now eligible for the flu vaccination and national letters have been sent by first class post to this group ... In the days leading up to Christmas there will be limited flu clinics across Lanarkshire, as less people need to be vaccinated.

“Staff will then have a well-earned break.”
