efficacy against the SA variant hasn't been demonstrated, the lead of the Astrazeneca vaccine says he's "concerned" because the new mutations are on the part that codes for how it interacts with antibodies
Apparently "hasn't been demonstrated yet" means "it won't work"? It was already demonstrated for the British variant. It is extremely unlikely any strain will render the vaccines useless, at worst they may be less effective.
We did make one. It's being distributed now.
This is doomer stuff.
