COVID-19 vaccination
After receiving COVID-19 vaccination, aviation duties should not be undertaken for a minimum of 24 hours after each dose of vaccination.
As stated in the CASA clinical practice guidelines, this waiting period is similar to and required after receiving any other vaccination/immunisation. In the absence of any side-effects 24 hours after vaccination, the licence holder can resume flying or controlling duties. Should the licence holder feel unwell beyond the 24 hours after vaccination, the pilot or the controller should not fly or control until their symptoms have resolved and/or they have been cleared to return to aviation duties by their doctor or DAME.
Have had 2x Pfizer. 24hr grounding after each (as it happened I didn’t have to fly for a longer period than that).
slight discomfort at the injection site for maybe up to 36hrs but a stubbed toe hurts more. otherwise fine.
To compare, moderna vaccine, FAA requires minimum 48hours.
