The World Health Organization on Tuesday warned Omicron was spreading at an unprecedented rate and urged countries to act as drug maker Pfizer said its coronavirus pill was effective against the variant.
Dutch primary schools will close early as Europe battles a fresh wave of infections and hospital admissions, while British Prime Minister Boris Johnson faced a major parliamentary test seeking to impose fresh Covid curbs.
Omicron, first detected by South Africa and reported to the WHO on November 24, has a large number of mutations, setting alarm bells ringing since its discovery.
The WHO chief also voiced concern that many countries are rushing to provide booster vaccine doses in response to the spread of Omicron, in light of the persistent glaring inequity in vaccine access between wealthy and poorer countries.
“WHO is concerned that such programmes will repeat the Covid-19 vaccine hoarding” seen previously this year, he said.
He said there was not yet enough data to show a third dose is needed to effectively protect healthy adults against the variant, although he said that “as we move forward, boosters could play an important role.”
At the same time many vulnerable people in poorer countries have not yet received a single dose.
“Let me be very clear: WHO is not against boosters. We’re against inequity. Our main concern is to save lives everywhere,” Tedros said.
“It’s a question of prioritisation,” he said.
“The order matters. Giving boosters to groups at low risk of severe disease or death simply endangers the lives of those at high risk who are still waiting for their primary doses because of supply constraints.”
