This is the place to watch as a guide to how Covid will play out for the rest of the year. The UK did an impressive job reeling in an out-of-control situation through a combination of restrictions and vaccines - but some are predicting a resurgence
Prof Ravi Gupta, University of Cambridge: Of course the numbers of cases are relatively low at the moment - all waves start with low numbers of cases that grumble in the background and then become explosive, so the key here is that what we are seeing here is the signs of an early wave.

BBC: He said the number of people who had been vaccinated in the UK meant this wave would probably take longer to emerge than previous ones.

Gupta: There may be a false sense of security for some time, and that's our concern.

Interesting that he talks about vaccines giving a 'false sense of security'. If the security vaccines offer from Covid is false then you wonder what's the point.

The big test is whether they can handle the Indian variant. We know they are useless against the SA variant, but that doesn't seem to have spread as widely as the Indian one.

Media has broadly announced that AZ is "highly effective against Indian variant" but as we discovered when you looked deeper at the data, even the researchers had low confidence in that pronouncement - and as Gupta says - all outbreaks start out with small numbers.
