Why does it take that long?

Does Geert Vanden Bossche actually know what he’s talking about, or does he just have a bit too much phantasy? Earlier this year, he claimed that a more virulent coronavirus would emerge in highly COVID-19 (C-19) vaccinated countries by the end of June, but - once again - he has misjudged that timeline. Can we still take that man seriously? Or is this just a miscalculation of at most a few weeks, and will his predictions still come true this summer?
