Virologist Dr. Chris Barbara has stated that as long as people choose to remain unvaccinated, new COVID-19 variants will keep cropping up.
This was stated during an interview on current issues programme TVAM which discussed the emergence of Omicron, the heavily-mutated COVID-19 variant which originated in South Africa and has since been spread in various countries across Europe. He highlighted that while many variants have emerged, the Omicron variant in particular is of concern.
The virologist explain that while variants normally contain mutations, the Omicron variant in particular has around 50 mutations, with around 30 of them being relevant to what is called the spike protein; that with which the virus uses to enter human cells.
Despite this, Dr. Barbara noted that there has yet to be an increase in cases or any deaths.
