According to the modelling, various different opinions in terms of optimistic/pessimistic. But overall, it appears as though where many of the modeller's expected to be right now, i.e. teetering on the brink of pandemic/endemic and the major fluctuations in case numbers in the UK at least.. Serious question, and elephant in the room, where are we in terms of vaccine updates? It's been said many times since they've been rolled out that they're relatively easy to tweak. Haven't heard anything on any of the major news outlets about them being updated from any of the main players and keeping pace.
