It's not really widely reported. There's been a small study that AZ vacc wasn't effective against mild to mod illness with SA variant but there were no hospitalizations or deaths. We are not getting to zero virus ever so the aim really is preventing severe illness and death and all the vaccines are still thought to achieve this even with the current variants so not all doom and gloom.
This is a good indepth article about variants and it's worth noting that the uk variant has been found to have mutated again in the same part as the SA variant so it's clear that variants will arise whether we travel or not but that's not to say we don't need to be careful.
'Tests show they have a mutation, called E484K, that is already seen in the South Africa variant.
Although this change may reduce vaccine effectiveness, the current ones in use should still work, say experts.'

How many months ago was it that the MSM was telling us all that the variant found in Danish Minks was going to do us all in ?
Not heard of any people in the UK or even Denmark going into hospital after contracting that variant.
