Looks like the odds are Triple vaxxed are twice as likely to test positive as double vaxxed according to latest ONS figures. This might be because triple vaxxed are more paranoid and testing more or there's now twice as many triples as doubled out there, but clearly being triple vaxxed is not stopping the spread - so if true a full lockdown and for longer would be even more likely.
I expect a lot of smaller clubs won't accept BCD without sufficient compensation guarantees, so it could be a right old mess again with the World Cup putting extra pressure on leagues to finish the season on time.
