Incidentally, I've just entered my first race abroad for 12 months, next July in the Pyrenees. I'm hoping I'll have been vaccinated by then, and that the race will actually go ahead, but I think I'll hold-off on committing any more money other than the race fee for a while. I'm optimistic, but not that optimistic!
(Sorry if anyone thinks I'm going off-topic and sullying the ethos of this Fell Running Forum by mentioning a trail race.)
