MINI THREAD: One way in which the Kent (B117) variant might help us vs SA variant... Both are more transmissible that older variants & so quickly become dominant.
BUT SA not more transmissible than Kent (we think) - so Kent, already dominant in UK, should stay dominant. 1/2

This is good because all vaccines work well against Kent (B117) & it doesn't seem to be re-infecting people who've already had covid.
But SA can re-infect people & evade (somewhat) AZ vax. Unknown is how that might help SA over time as it has more people it can spread to. 2/2

PS2 yes B117 will likely acquire the Eeek mutation (and already has at least once, but so far minimal onward transmission I think). And yes the more people get vaccinated with AZ, the more advantage that might give SA variant - but it all buys us valuable time to drive cases down
