Evidence is mounting that the Delta variant of coronavirus is capable of infecting fully vaccinated people at a greater rate than previous versions, and concerns have been raised that they may even spread the virus, experts said, according a Reuters report.
“The biggest risk to the world at the moment is simply Delta,” said microbiologist Sharon Peacock, who runs Britain’s efforts to sequence the genomes of coronavirus variants, calling it the “fittest and fastest variant yet”.
The major worry about the Delta variant is not that it makes people sicker, but that it spreads far more easily from person to person, increasing infections and hospitalisations among the unvaccinated.
