"Summary: The BA4/5 sister variants currently dominate two countries: South Africa and Portugal. South Africa is barely vaccinated (only 35% had a vaccine, 5% had a booster), whereas Portugal is 95% vaccinated and 70% boosted.
The situations in these countries could not be any more different: while Ba.4 and Ba.5 were mere blips on the radar in South Africa, these 
same variants are driving a deadly wave of Covid in highly-vaccinated Portugal, with deaths among the Portuguese nearing January peak and showing few signs of abating."
