If it is true, then in the long run AZ vaccine is close to useless. B.1.351 will just spread all over the world as quickly the original virus did, and we'll have to revaccinate with something else anyway. Which can also be complicated if something else is a viral vector vaccine too.
I understand they are already modifying the vaccine to handle the B.1.351 variant so all that will be needed is a third booster shot for people who have already got the AZ vaccine.
In the UK we vaccinate for whatever variants of the flu are circulating every year, Corona is going to be the same. I've heard experts widely state that since the pandemic started.
