Studies are still in an early stage, as the variant was only detected on November 24.
There is no evidence that omicron causes a more serious disease than previous variants of the coronavirus and no reason “to doubt” the efficacy of vaccines against the new variant, a senior WHO official told AFP on Tuesday.
“We have very effective vaccines that have proven their power against all variants so far, in terms of severity of the disease and hospitalization, and there is no reason to think that this will not be the case” in the case of omicron, explained the WHO emergency director, Michael Ryan.

“The general pattern that we are seeing so far does not show an increase in gravity. In fact, in some places in southern Africa milder symptoms are being registered, “said the doctor, echoing what the American scientist Anthony Fauci had previously told AFP.
“You have to be very careful with the analysis” of these data, Ryan stressed however, recalling that the studies are still in an early stage, since the variant was detected in South Africa only on November 24.
Since that date, cases have been registered in about 40 countries. (I)
