Medical letter of exemption
Medical letter of exemption from the requirement for an International Certificate of Vaccination or Prophylaxis (ICVP)
Where a health professional advises that an individual should not be vaccinated on medical grounds, a medical letter of exemption (MLOE) should be provided for entry to countries where a certificate is required. The MLOE is only valid for one trip and should be taken into consideration by the port/border health authorities in the destination country.
The current ICVP yellow booklets (2024) used in the UK, have a template for a MLOE; this can be completed and stamped at designated Yellow Fever Vaccination Centres (YFVC). Extra ICVP can be ordered by contacting Harlow Printing Ltd.
A MLOE does not need to be written by the YFVC; it is acceptable for a health professional supervising the care of an individual, but not working in a YFVC to provide this documentation if appropriate. In such instances, the MLOE can be written on headed paper of e.g. a hospital, clinic or medical centre (see example template below).
