Omicron Evades Sinovac, Study Shows

The omicron variant infects around 70 times faster than delta and the original Covid-19 strain, though the severity of illness is likely to be much lower, according to a University of Hong Kong study that adds weight to the early on-ground observations from South African doctors.

The supercharged speed of omicron’s spread in the human bronchus was found 24 hours following infection, according to a Wednesday statement from the university. The study, conducted by a team of researchers led by Michael Chan Chi-wai, found that the newest variant of concern replicated less efficiently -- more than 10 times lower -- in the human lung tissue than the original strain which may signal “lower severity of disease.”
