next variant of concern will most likely be more transmissible as compared to Omicron because it will have to overtake the strains that are currently circulating, said Maria Van Kerkhove, the technical lead of the World Health Organisation (WHO), on Sunday.
In addition to this, she warned that future variants may also have a greater ability for immune escape, meaning the vaccines will not be as effective against them. “We do not want to be in that situation.
So, we want to make sure that we reduce the spread," she said. “We expect that with the right interventions, the circulation of Covid-19 will be low.
But even within those circulations, there will be flare-ups among people who are not protected by the vaccine or those who have waning immunity," added Kerkhove.
