General advice for flying / controlling post vaccination or immunisation

  • In the absence of any side-effects 12 hours after vaccination there are no restrictions to resuming flying or controlling duties.
  • Should a pilot or ATCO develop a fever or feel unwell, whether associated with vaccination or not, they should not fly or control until symptoms have resolved and/or they have been cleared to fly by their AME/physician.

The following are the requirements for the medical certification of aircrew, including guidance material issued by the UK CAA Medical Department in relation to Infectious diseases.
