Due the actions of a few thousand extremely selfish people, the UK is now looking like riding a third wave of the virus. Something everyone took on the chin back in December to make sure we didn't screw up the roll out of the vaccinations and have a 3rd wave raging in the middle of it.
Now with half the adults fully vaccinated and vaccination going apace, we should see whether this is going to work or not. This is the litmus test. If the latest outbreak fizzles then we are on stronger ground to get on with our lives.
The next 3 weeks will be vital to see the trend. This time unlocking on the 21st really will be data driven. Not data that shows that everything has stopped and it is safe, but data which shows that vaccinations will curb any future outbreak.
