Vaccination key to battling Omicron says WHO

The World Health Organisation (WHO) urged countries to boost healthcare capacity and vaccinate their people to fight a surge in Covid-19 cases driven by the Omicron variant, saying that travel curbs could buy time but alone were not the answer.
Despite shutting its borders to travel from high-risk southern African countries, Australia became the latest country to report community transmission of the new variant, a day after it was found in five US states.
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.
"Border controls can buy time but every country and every community must prepare for new surges in cases," Takeshi Kasai, the WHO's western Pacific director, told a media briefing.
"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.
Omicron has been listed as a "variant of concern" by the WHO and scientists are still gathering data to establish how severe and contagious it is just as parts of Europe have been hit by surges of winter infections by the more familiar Delta variant.
"I have not seen reports of Omicron-related deaths yet," WHO spokesman Christian Lindmeier told a UN briefing in Geneva.
But vaccine makers should prepare for the likelihood of adjusting their products to protect against Omicron, he said.
WHO's chief scientist Soumya Swaminathan yesterday urged people not to panic over the emergence of the Omicron 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, Swaminathan also said it was impossible to predict if Omicron would become the dominant strain.
