"Zero Covid" apparently doesn't mean zero Covid any more, just "low levels like last Summer". Given that people associated with zero covid, like Devi Sridhar, don't think it went low enough last summer, I think that's not a good slogan, but anyhow.
Sure, New Zealand did extremely well, but it only had 2,300 cases of Covid in total. Gross that up to the UK population, and that's something like 28,000. We just had that many in a day. How long would it take to get down to this level? And if you're vaccinating fast, with the most vulnerable being done as you go, does that make sense anyway?
Mark Drakeford doesn't seem to be aiming for this. But I'm sure the bloke who last held political office in the seventies on a council housing committee knows better.
