Really? Link would be nice.
Given definitions of a pandemic are generally about its international nature, I'm not sure that declaring it over in one country is even meaningful:
“an epidemic occurring worldwide, or over a very wide area, crossing international boundaries and usually affecting a large number of people”
Plus, it's for sure not over here; according to ONS today about 90,000 people currently have the disease, and about 40% of the population or so remain unvaccinated and susceptible.
Estimates for England, Wales, Northern Ireland and Scotland.

Controlled? Suppressed? Sure.
Over? Definitely not yet IMO.
