We also have MedJet and they said recently that they had acquired a Covid evacuation plane which will serve the Caribbean. This must have been a very profitable year for them, given that no one was traveling and they didn't have to evacuate many people!
I was thinking the same thing yesterday.
Another answer might be hidden in the COVID protocols for hotels and villas. We are obligated to block a quarantine room to be used for any guests testing positive or exhibiting symptoms. I don't remember all the details but that requirement is amongst the 28 pages of protocols.
