So a “pragmatic” doctor giving you an exemption for a non-mandatory vaccine which may endanger your aviation medical. Doesn’t sound like a very smart doctor to me.
OR
You’re full of sh*t.
I’m going with the latter.
Reminds me when our airline made masks mandatory for staff (before it become mandatory for pax). There was an uproar from cabin crew and how they would be obtaining exemptions. It was pointed out from our medical officer that if you need an exemption then you’re not suitable for duties on an aircraft. That shut them up quick smart. Now it’s turned to vaccinations and as another poster has pointed out, they’ll need it for international flights and I’d imagine my airline will remove these people from international duties and place them on LWOP.
