Work will only allow me to take a month off in a year, lol an I am certainly not spending it cooped up in a crappy hotel room for $6000. Also if they are waiting for the vaccine then the soonest possible date based on their own stipulation would be spring or summer of 2022. Since for people to develop prolonged antibodies you would need to:
get the vaccine which should be available to a small group of people starting possibly in Jan/Feb
get a 2nd dose of the 3 dose series 120 days later so May/June
get the final dose 90-120 days after that so Sept/Dec
Realistically its looking like late 2023 or early 2024. How would their economy they hold off until then is anyone's guess.
