Still too soon to say if Omicron more transmissible than Delta: WHO

“We do have some data suggesting that rates of hospitalisation are lower,” WHO’s technical lead on COVID-19, Maria van Kerkhove, said in a briefing with media.

But she cautioned against drawing conclusions from the early data because “we have not seen this variant circulate long enough in populations around the world, certainly in vulnerable populations”.

She said the data on the new variant, first identified in southern Africa and Hong Kong in November, was still “messy” as countries reported its arrival and spread.

The U.N. agency’s experts regularly meet drugmakers to discuss the best composition of COVID-19 vaccines as the industry looks at whether shots need to be tweaked to tackle the coronavirus.

The comments on Omicron came as a South African study suggested that those infected with Omicron were significantly less likely to end up in hospital than those with Delta, although the authors said some of that was probably due to high levels of immunity in the population.

The head of the WHO, Tedros Adhanom Ghebreyesus, urged countries to learn from the past two years of the pandemic, calling again for greater vaccine equity, in the hope of next year ending a pandemic that has killed over 5.6 million people around the world.

“As we approach the new year, we must all learn the painful lessons this year has taught us. 2022 must be the end of the COVID-19 pandemic,” he said.
