New vaccine research needed to tackle emerging COVID******

As the global COVID-19 death toll has passed 5.4 million amid a surge in Omicron cases, an expert from the Imperial College London (ICL) said that research on new vaccines and stronger global collaboration may be needed to tackle emerging COVID-19 variants.。

"The question about whether there's going to be another variant that is even more transmissible and more infectious than Omicron, we don't know yet," Dr. Katrina Pollock, who leads the COVID-19 vaccine project at the ICL, told Xinhua in an online interview on Thursday.。

"I think it's too early to say and that's why we need to have surveillance of these variants and global collaboration so that we can understand what's happening," said the senior clinical research fellow in vaccinology and honorary consultant at the ICL.。

Some two years into the pandemic, the death toll from COVID-19 has topped 5.4 million worldwide, amid a total of 296 million cases recorded, according to the World Health Organization .。

"Different viruses have different rates of making new variants, but they are all governed by the same principle which is that the more easily they are to transmit the more you'll see them," Pollock said.。

"What we're seeing with Omicron is that it's very infectious, and it makes many copies of itself very quickly. That means that we're seeing very, very high infection rates," she said.。

According to WHO data, some 128 countries had reported cases of the Omicron variant as of December 29, 2021.。

New vaccine research。

Asked about whether new vaccines will be needed to tackle highly transmissible new variants, Pollock said that new vaccines may be needed to provide better protection.。

"Certainly, with Delta, we were still seeing high vaccine effectiveness in real world studies against the virus. But it's possible that in the future we may need to change the vaccine, there may be some advantage to have a new strain in the vaccine to provide better protection," she said.。

"What we really need to see is that vaccines are going to help drive down transmission because that's how we get control over the pandemic," she emphasized.。

Early studies showed that more evidence is emerging that the Omicron coronavirus variant is affecting the upper respiratory tract, causing milder symptoms than previous variants.。

Pollock said that significant research and development should also be done on developing new and effective treatments such as antivirals and immune modulating treatments.。

Better phase。

Asked about whether she was optimistic the pandemic could be over this year, Pollock didn't think so.。

"I mean, it would be really wonderful if it were. But we've talked about the new variant and the transmission and the need to get everybody vaccinated. I think this means that we're going to be living with this virus for a while," Pollock said.。

"But we have made great strides and amongst all the tragedy, we also have to have some cause for being positive particularly about vaccination, because it is helping avert what would have been a much worse global disaster if we've not been able to make those vaccines," she said.。

"In a nutshell, I don't think it's going to be over this year. But I think you know, with the research and the coordinated efforts, we may move to a better phase," she added.。

Call for global collaboration。

Asked about the stronger global measures which should be put in place against new variants of COVID-19, she stressed the importance of ensuring access to vaccines and the primary doses to people and controlling transmission instead of just "controlling severe disease and death."

The WHO has set a target for countries to vaccinate 70 percent of their population by mid-2022. However, the organization said in December last year that 98 countries have not yet vaccinated 40 percent of their population, stressing that about 1.4 billion eligible people need to be urgently immunized.。

Pollock highlighted that the most important thing in tackling the pandemic in the long-term was international collaboration.。

"As long as we continue to collaborate globally and to break down those doors with scientists, politicians and public health experts, that incredible collaboration effort that started in 2020, I think if that can continue, then we will move as a global population away from the bad situation that we're in now," she said.。

"The worst scenario would be if people step away from those kinds of collaborative efforts," she stressed.。

MOSCOW, Nov. 27 (Xinhua) -- Morisi Kvitelashvili of Georgia made history on Saturday when he won his country's first ISU figure skating Grand Prix title at the Rostelecom Cup in Sochi, Russia.。

Meanwhile, Russian skaters collected the championships of al the other three events with a clean sweep of both the women's and pairs podiums.。

Skating to "Fly Me to the Moon" and "My Way" in the men's free skate, Kvitelashvili, the 2020 European bronze medalist, opened with a quad Salchow-double toe, a triple Axel, quad toe-triple toe, and followed up with three more triples. His only major error came when he fell on a quad toeloop.。

The program earned him 170.96 points and ranked third in the men's free skate, but moved him up from second to first at 266.33 points overall for a historical victory.。

It's also Kvitelaashvili who won Georgia's first ISU Grand Prix medal in 2018.。

"Not everything worked in my program, but I tried hard, I fought and I am happy to be on the podium," Kvitelashvili commented.。

"We are making history and we have other great skaters in our team. We're going to have a complete team at the Olympic Games in Beijing, that's also a first," added the 26-year-old.。

Russia's Mikhail Kolyada, bronze medalist of the 2018 world championships, climbed up from fourth to claim the silver, while overnight leader Kazuki Tomono of Japan settled for the bronze.。

On the women's part, Kamila Valieva, just 15 years old, cemented her status as the title favourite for Beijing 2022 with another top-scoring skate in Sochi, beating fellow Russian Elizaveta Tuktamysheva and Maiia Khromykh to the second and third place.。

Performing to Ravel's "Bolero", Valieva, the 2020 junior world champion, reeled off a quadruple Salchow, quad toe-triple toe, quad toe-Euler-double Salchow, triple Axel as well as four triples and difficult spins and footwork that all garnered a level four, setting a new record score of her own in free skate - 185.29 points.。

Having already registered a world-record score for her short program on Friday, Valieva totaled 272.71 points and broke her own previous record of 265.08.。

The 2015 worlds' champion and 2021 runner-up Tuktamysheva ranked third in free skate with a score of 149.13 but remained in silver medal position with an overall result of 229.23. Khromykh climbed from fifth to third with a personal best of 154.97 in free skate and 219.69 in total.。

Reigning pairs world champions Anastasia Mishina/Aleksandr Galliamov overtook the first place from compatriots Daria Pavliuchenko/Denis Khodykin after a dynamic performance in the free skate earned them 153.34 points for a total score of 226.98.。

They were 14.39 points more than the silver medalists. Iasmina Kadyrova/Ivan Balchenko earned the bronze with 124.19 in free skate and 193.58 overall.。

American-born-Chinese Audrey Lu and her partner Misha Mitrofanov, who finished fifth in the NHK Trophy on November 12-14, finished fourth in Sochi, missing a qualification to next month's GP Final.。

World champions Victoria Sinitsina/Nikita Katsalapov of Russia won their second GP gold of the season, and Italy's Charlene Guignard/Marco Fabbri earned the silver, both having secured their places in the Final. The bronze went to Laurence Fournier Beaudry/Nikolaj Sorensen of Canada.。

The GP Final will take place in Osaka, Japan on December 9-12, with top six skaters/combinations in each discipline of the season's six senior GP events qualifying for the Final. Enditem。
