Is Omicron the last variant?

We're all no doubt very tired of the pandemic by now and could be forgiven for hoping now that Omicron has landed in Australia, once we get over the current outbreak it's all over.But according to evolutionary virologist Eddie Holmes, sadly Omicron won't be the last and in fact the next variant probably won't evolve from Omicron.So what can we do apart from get vaccinated and hope this terrible roller coaster ride will somehow end soon?
