Joe Biden Warns of ‘Potentially Deadlier’ Delta Variant of Coronavirus

On a semi-related note... both the UK and Canada not only have used the AZ vaccine as a major portion of its shots, but they've also delayed the second shot for months for most of its citizens, hence why much of Canada is still in lockdown. Even though AZ uses the same technology as J&J, it is far less effective with the single shot than J&J: by some estimates, AZ is only 30% effective with one shot (compared to 60-70% with J&J or the first shot of either Pfizer or Moderna).

So that's why we're seeing issues with the UK still seeing an increase in cases despite as much vaccination as they've done.
