I did a lot of travelling prior to retirement and was not nervous when flying but I've decided never to board a plane again. It's not just vaxxed pilots that worry me but air traffic controllers, those servicing/repairing/fuelling/loading the aircraft. Even ordering the spare parts. In my early career I worked in defence procurement mostly ordering spare parts for Australia's Mirage fleet before it was retired. You need to have your wits about you to do those jobs. A brain-fogged procurement clerk shipping wrong spare part to equally brain-fogged maintenance guy can have dire consequences. Many screws fit one screw hole and incorrect or incorrectly fitted screws/bolts etc. can have disastrous consequences in aviation industry, even if supply chain is now fully automated.

Air New Zealand also modified it cardiac screening, no longer required until 40yrs from memory.

In line with FAA changes (probably international given the requirement in aviation to keep regulations as harmonized as possible), I think the ECG PR interval has been extended to 300ms.

Reportedly, "A PR interval of less than 200 milliseconds is considered normal, and participants whose interval was longer than 200 milliseconds had twice the overall risk of developing atrial fibrillation, three times the risk of needing a pacemaker, and almost one and a half times the risk of early death."
