It's likely that even if the pandemic is over vaccination still will need to be done for years to come (to prevent a new pan-/epidemic).

It's also likely that people on all sides of the contract thought that it will be more or less over at that point in time and the clause exists solely to prevent governments from just never declaring the pandemic from being over.

I also doubt that a clause like that is actually legal, tbh.

But hey maybe I'm just to optimistic.
