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.。

Verstappen wins 2021 F1 title with last******

by F1 correspondent Michael Butterworth。

BEIJING, Dec. 12 (Xinhua) -- Red Bull's Max Verstappen won the 2021 Formula 1 world championship after passing Mercedes' Lewis Hamilton for the lead on the last lap of a scarcely believable Abu Dhabi Grand Prix on Sunday.。

In a climax befitting one of the most dramatic and enthralling seasons in F1 history, Hamilton had led comfortably until a late-race safety car period wiped his lead out and allowed Verstappen to pit for a new set of soft compound tyres.。

After the stricken Williams of Nicholas Latifi was removed, the safety car peeled in to allow for one final lap under racing conditions, but race director Michael Masi controversially allowed the lapped cars sitting on track between Hamilton and Verstappen to overtake the safety car, meaning the two title rivals entered the race's final lap nose to tail.。

Mercedes felt aggrieved at Masi's decision, believing that the lapped cars should not have been able to overtake, as is normal practise, and it appeared as if Masi had changed his initial decision at short notice.。

With vastly superior grip from his fresher rubber and no backmarkers in the way, Verstappen dived up the inside of Hamilton at turn five and held on to win a race he had not led a single lap of up to that point.。

For his part, Hamilton had entered the weekend with the wind in his sails, coming off the back of three wins in a row for the first time this season.。

The Briton's run of good form meant he and Verstappen started the race absolutely level on points - the first time two F1 title rivals have been deadlocked ahead of the last race since 1974.。

Though Verstappen grabbed pole position on Saturday, Hamilton made by far the better start and took the lead at turn one, despite Verstappen's best efforts to overtake him at the hairpin.。

Settling down in the lead, Hamilton appeared to have an answer for everything Verstappen and Red Bull could throw at him, including having Verstappen's teammate Sergio Perez hold him up to allow the Dutchman to close on the Mercedes.。

However, just when it seemed as if Hamilton would win the race and take a record eighth world title, Latifi spun into the barriers to bring out the safety car and set up the grandstand finale.。

"It's unbelievable. Throughout the whole race I kept fighting and to have an opportunity on the last lap, it's incredible," said Verstappen afterwards.。

"My team know I love them and I hope we can do this for 10-15 years together. There's no reason to change ever, I want to stay with them for the rest of my life. I hope they let me."

"[Team boss] Christian [Horner] and [special advisor] Helmut [Marko] trusted me to be in the team in 2016, our goal was to be world champion and now we've done that."

Hamilton was magnanimous in defeat after a race in which he had not put a foot wrong.。

"Congratulations to Max and to his team. I think we did an amazing job this year. My team have worked so hard this whole year, it's been the most difficult of seasons. I'm so proud of them and I'm so grateful to be a part of the journey with them."

Behind the top two, Ferrari's Carlos Sainz took third, with the twin AlphaTauris of Yuki Tsunoda and Pierre Gasly finishing a strong fourth and fifth.。

Hamilton's teammate Valtteri Bottas finished a disappointing sixth in his last race for Mercedes, with McLaren's Lando Norris taking seventh. The Alpines finished eighth and ninth, with Fernando Alonso ahead of Esteban Ocon, and Sainz's teammate Charles Leclerc rounded out the top ten.。

Some consolation for Mercedes came as the Silver Arrows sealed the constructors' championship for a record-extending eighth year in succession, with Red Bull second and Ferrari third.。

The 2022 Formula 1 season begins with the Bahrain Grand Prix on March 20, where the cars are set to look and perform very differently, as teams will have a brand new set of technical regulations to abide by.。

But the 2021 season will live long in the memory of everyone who watched one of the most dramatic, controversial and enthralling years the sport has known since its inception in 1950. Enditem。
