New COVID-19 variant described as 'worst one yet' emerges in South Africa
Britain bans travellers from six countries as scientists identify a new coronavirus variant they say has mutations likely to make it more infectious and resistant to vaccines.

New variant in South Africa.
This is worrying:
The UK Health Security Agency (UKHSA) said B.1.1.529 had a spike protein that was dramatically different to the original coronavirus variant the vaccines were based on.
It said it had mutations that were likely to evade the immune response generated both by prior COVID-19 infection and vaccination.
It also had mutations associated with increased infectivity, the UKHSA said.
