Spike After Spike?

The assumption that the Covid19 pandemic is 'over' seems distinctly premature. One problematic variant has been followed by another. The new XBB variant is a version that seems to largely overcome immune defences acquired by prior infection and/or vaccination. Singapore has seen almost 12,000 new cases (largely of XBB) in a single day (https://www.straitstimes.com/singapore/health/new-covid-19-cases-more-than-double-from-previous-day-but-severe-cases-remain-low). XBB usually doesn't appear to cause severe Covid19 infections. The fact that it has arisen, however, clearly suggests that Covid19 is going to be with its human hosts/vectors for the long term. There are likely to be more problematic variants of this virus.
