Valneva meanwhile has said its whole inactivated vaccine could have an advantage as it stimulates the immune system to recognise other viral proteins as well as spike, so could be less vulnerable to escape variants.
The mRNA vaccines are likely the easiest to update as they are based on a genetic sequence that can be modified relatively easily in the lab, but still need to be scaled up and tested to allow mass production.
If B.1.1529 can evade current vaccines it will be a worrying development in the pandemic, but experts have also pointed out that is also possible that the mutations could make the virus less virulent.
