We are aware that a small number of patients with previous glandular fever have incorrectly received a letter from the NHS recommending that they book a free flu vaccination.
Having glandular fever previously does NOT put you at greater risk of complications from the flu.
The NHS apologises if this has caused any anxieties or health concerns.
If you received one of these letters incorrectly you will be written to again to let you know you do not need to book a flu vaccination now.
