These new variants were to be expected as the vaccines seem to be accelerating these mutations.
My understanding is that the COVID vaccines train the body to recognize the outer protein layer of the virus. In consequence when that changes (because of mutations and natural selection) the body becomes less effective at recognizing the virus.
Geert Vanden Bossche[1] has been warning about this for months now. He says it's possible at some point a new variant will come out that makes current vaccines completely ineffective.
