Reuters reported that Oxford University said on Tuesday that there was no evidence so far that vaccines would not protect against severe disease related to the Omicron variant.
"Despite the appearance of new variants over the past year, vaccines have continued to provide very high levels of protection against severe disease," it stated, adding that "there is no evidence so far that Omicron is any different".
The university also noted that it was ready to quickly develop an updated version of its coronavirus vaccine designed in collaboration with AstraZeneca (AZN) if necessary.
