But Travel from South Africa has not been stopped?

This was always the gamble of the traditional viral-vector vaccines (Oxford, Russian etc.) vs the newer, more expensive mRNA vaccines (Pfizer, Moderna). They are less likely to be as effective on new strains. They're likely to still be somewhat effective but might be a lower percentage (and thus no herd immunity).

HOWEVER even if they are still effective just in limiting severity, that's the biggest concern. If it still runs through the population but non-mild cases are extremely rare, then that's half the battle.
