WHO's chief scientist advises against panic over Omicron, emphasizing readiness and potential vaccine updates as Omicron spreads globally.

GENEVA (Reuters) – The World Health Organization’s (WHO) chief scientist on Friday urged people not to panic over the emergence of the Omicron coronavirus variant and said it was too early to say if COVID-19 vaccines would have to be modified to fight it.
Speaking in an interview at the Reuters Next conference,
Soumya Swaminathan also said it was impossible to predict if Omicron would become the dominant strain.
Omicron has gained a foothold in Asia, Africa, the Americas, the Middle East and Europe and has reached seven of the nine provinces of South Africa, where it was first identified. Many governments have tightened travel rules to keep the variant out.
Swaminathan said that the right response was to be ready.
“How worried should we be? We need to be prepared and cautious, not panic, because we’re in a different situation to a year ago,” she said.
“Delta accounts for 99% of infections around the world. This variant would have to be more transmissible to out-compete and become dominant worldwide. It is possible, but it’s not possible to predict.”
Much remains unknown about Omicron, which has been detected in more than two dozen countries as parts of Europe grapple with a wave of infections of the more familiar Delta variant.
“We need to wait, lets hope it’s milder … but it’s too early to conclude about the variant as a whole,” Swaminathan said.
Australia became the latest country to report community transmission of the new variant, a day after it was found in five U.S. states.
WHO spokesman Christian Lindmeier told a United Nations briefing in Geneva earlier that vaccine makers should prepare for the likelihood of adjusting their products.
Ugur Sahin, CEO of Germany’s BioNTech, which makes a COVID vaccine with Pfizer, told the Reuters Next conference the company should be able to adapt the shots relatively quickly.
Sahin also said current vaccines should continue to provide protection against severe disease, despite mutations.
Takeshi Kasai, the WHO’s western Pacific director, told a media briefing that vaccines were the solution and that border controls could only buy time.
“People should not only rely on border measures. What is most important is to prepare for these variants with potential high transmissibility. So far the information available suggests we don’t have to change our approach.”
Kasai urged countries to fully vaccinate vulnerable groups and stick to preventive measures such as mask wearing and social distancing.
Almost 264 million people have been reported to be infected by the coronavirus since it was first detected in central China in late 2019 and 5.48 million people have died, according to a Reuters tally.
Vaccination rates vary from country to country but there are worrying gaps in poorer countries. Indonesia, the world’s fourth most populous country and once Asia’s COVID-19 epicentre, has fully inoculated only about 35% of its population.
Australia’s chief medical officer, Paul Kelly, said Omicron was likely to become the dominant variant globally within months, but at this stage there was no evidence it was any more dangerous than Delta.
In the United States, the Biden administration announced measures to guard against the virus spreading. From Monday, international air travellers arriving in the United States will have to have obtained a negative COVID-19 test within a day of travel.
“We’re going to fight this variant with science and speed, not chaos and confusion,” President Joe Biden said.
Fewer than 60% of the U.S. population have been fully vaccinated, one of the lowest rates among wealthy nations.
Aside from wreaking havoc in the travel industry, the clampdown has pounded financial markets and undermined major economies just as they were beginning to recover from the lockdowns triggered by Delta.
Bank of England policymaker Michael Saunders, who voted for an interest rate hike last month, said on Friday he wanted more information about Omicron before deciding how to vote this month.
“At present, given the new Omicron COVID variant has only been detected quite recently, there could be particular advantages in waiting to see more evidence on its possible effects on public health outcomes and hence on the economy,” Saunders said in a speech.
Germany said it would bar the unvaccinated from all but essential businesses, and legislation to make vaccination mandatory would be drafted for early next year.
Several countries, including Britain and the United States, were bringing forward plans to offer booster shots, but, like travel bans, they are controversial.
Many scientists say the way to stop the virus spreading is to make sure poorer countries have access to vaccines, not to give blanket booster shots to people in richer countries.

The article discusses the WHO's advice on handling the Omicron variant without panic and the potential need for vaccine updates.
WHO advises preparation and caution rather than panic, as Omicron's full impact is still being studied.
Current vaccines are expected to offer protection against severe disease, though modifications may be needed.
