Wrenhaven's health service is adding late sessions at three community clinics after appointments for the first week of the autumn vaccination programme were fully booked within days.
Extra sessions at Kestrel Park, the university and Old Quay are being added as the regional blood service tries to build up stocks ahead of the colder months.
Practices across Wrenhaven say appointment demand typically climbs sharply in the colder months, and they are encouraging people to arrange non-urgent reviews and screening now.
Thirst can be easier to miss in colder weather, especially for older people, and local health professionals are encouraging regular drinks through the day rather than waiting until feeling parched.
