Study finds Omicron variant can partially escape immunity induced by Pfizer vaccine******

A laboratory research has suggested that the Omicron variant can partially escape antibody immunity induced by the Pfizer-BioNTech COVID-19 vaccine.。

The research, led by professor Alex Sigal from the Africa Health Research Institute in South Africa, has been submitted to medRxiv, a preprint server for health sciences.。

The research confirms predictions that the large number of mutations in the spike protein and elsewhere on the Omicron variant would translate into some evasion of the immune response induced by the Pfizer-BioNTech vaccine.。

Sigal said on Twitter Tuesday that his lab tested blood from 12 people who had been vaccinated with two doses of the Pfizer-BioNTech vaccine, and found that there was a 41-fold decrease in the ability of antibodies from the vaccine to neutralize the Omicron variant.。

Fresh Dutch COVID******

AFP。

Nursing staff assist a coronavirus patient in the nursing department of Maastricht UMC in Maastricht, the Netherlands, on November 10, 2021.。

European governments on Friday eyed unpopular COVID curbs, with the Netherlands opting for Western Europe's first partial lockdown of the winter as EU experts said 10 countries in the bloc were causing "very high concern."

Dutch premier Mark Rutte announced at least three weeks of lockdown measures targeting restaurants, shops and sporting events to curb a record spike in coronavirus infections.。

The "annoying and far-reaching" measures came as the EU's diseases agency said 10 countries in the 27-member bloc faced a COVID-19 situation of "very high concern," warning the pandemic was worsening across the continent.。

In its weekly risk assessment, the European Centre for Disease Control listed Belgium, Bulgaria, Croatia, the Czech Republic, Estonia, Greece, Hungary, the Netherlands, Poland and Slovenia in its highest category of concern.。

Europe is facing a sharp deterioration in the epidemic situation, especially in Germany and central and eastern Europe. Non-vaccinated people are the most affected.。

Announcing his country's partial lockdown, Rutte told the nation the crisis required a "hard blow of a few weeks because the virus is everywhere, throughout the country, in all sectors and all ages."

Cases have soared since the Dutch government lifted most COVID measures less than two months ago on September 25, reaching a record level of more than 16,000 on Thursday and Friday.。

"Fortunately, the vast majority have been vaccinated, otherwise the misery in the hospitals would be incalculable at the moment," Rutte said.。

Public events scrapped。

Bars, restaurants, cafes and supermarkets will have to shut at 8pm for the next three weeks from Saturday, while non-essential shops must shut at 6pm, the Dutch government said.。

People will be limited to having four visitors at home and have been advised to work at home unless absolutely necessary.。

Public events will also be scrapped while football matches including the Netherlands' home World Cup qualifier with Norway next week must be played behind closed doors. Schools will however remain open.。

Several hundred protesters angered by the announcement gathered in The Hague afterward, with police firing water cannon at them.。

Other European nations stopped short of such drastic action but Norway said it would reintroduce nationwide measures to stem surging coronavirus cases, including authorizing towns to use health passes.。

The Nordic country, which had lifted all COVID-19 restrictions in late September, will also propose a third vaccine dose for people over 18 but will not impose a new lockdown, Prime Minister Jonas Gahr Store told a news conference.。

"The government wants to introduce new national measures to contain contagions," he said.。

"However, we are not talking about confinements or measures as strict as we saw earlier in the pandemic."

Lockdown for unvaccinated。

In Austria, the government said it wanted a lockdown for those not vaccinated against or recovered from the coronavirus, while Vienna city authorities said they would start vaccinating children as young as 5 – a first in the EU.。

Salzburg and Upper Austria states, which have seen some of the worst case rates, are already introducing a lockdown for the unvaccinated from Monday.。

This means they will not be able to leave the house except for reasons such as buying essential supplies, exercise or seeking medical care.。

"The aim is clear: We want on Sunday to give the green light for a nationwide lockdown for the unvaccinated," Chancellor Alexander Schallenberg told a news conference, condemning the country's 65 percent vaccination rate as "shamefully low."

Lockdowns across the country would be enforced with "random" spot checks.。

Neighboring Germany also braced on Friday for new restrictions to contain a ferocious fourth COVID-19 wave.。

Health Minister Jens Spahn described the COVID-19 situation as "serious" while the country's health agency chief urged Germans to avoid large gatherings.。

Profile: Teen amateur golfer Yin to stand out from professionals******

By Zhang Yuanshinan and Wang Jingyu。

BEIJING, Nov.2 (Xinhua) -- Yin Xiaowen will never forget the night she was ordered to practice putting even after her golf club closed, with only the lights from her father's car illuminating the green.。

"I was really bored and annoyed at that moment," Yin recalled emotionally. "But when I realized I had made progress one day, I came to understand his decision and was full of gratitude."

Yin, 16, inherited her sporting talent from her parents. Her father Yin Jianhua was an amateur footballer for years and good at long-distance running, while her mother Zhang Chunyuan enjoyed badminton, tennis and swimming.。

Yin Xiaowen picked up a golf club for the first time when she was seven. The "whoosh" and "ping" of the club hitting the ball has been the soundtrack to her life ever since.。

"Golf gives me a uniquely different feeling from any other sport. I enjoy hitting the ball far very much," said Yin.。

In her first few months of playing golf, Yin unexpectedly won a children's invitational event. Her passion for the game grew rapidly and then she decided to receive formal golf training - two hours every day.。

At 10, Yin went to the United States for professional training and attended the Feng Shanshan Golf School in 2016. As the intensity of her training increased, the sport gradually dominated her life, even on holidays.。

Once Yin's mother took her to Tokyo's Disneyland Park. At the end of the day, she urged her mother to leave as she didn't want to skip her daily training.。

"Training and studying have constituted almost her whole life over the years. She took a day off only every two weeks," Yin's mother said.。

Years of hard work laid a solid foundation for Yin's steady improvement. In July last year, Yin became the youngest winner in China LPGA Tour history with a five-stroke victory in the Zhangjiagang Shuangshan Challenge.。

At Beijing Orient Pearl Country Club this year, Yin created more history when she won the Ladies Challenge to become the first and youngest-ever three-time champion on the China LPGA Tour.。

"I am happy to be the first amateur to win three times on the Tour, but I still have much work to do. Feng Shanshan is the role model for all Chinese players. Hopefully one day I can pick up the baton and win honor for my homeland like her," said Yin.。

With her driver swing distance reaching 280 yards, Yin already can match any of the world-class female golfers.。

Despite her young age, Yin has a profound understanding of the sport.。

"The difference between high-level athletes is small. What matters is the psychological condition," said Yin.。

"During a four-day event, I feel nothing on day one, but a bit stressed on day two. On the third day, tensions surge if I stay ahead. It is on the final day when 'buzzer-beaters' appear, and I feel very nervous that I will be overtaken at any time."

"But this process full of pressure and uncertainty is where the charm of golf is, I think," she added.。

Talking about her future, Yin has two goals - one is to officially qualify for the LPGA as a professional; the other is to represent China at next year's Asian Games in Hangzhou.。

"I admit that I have some talent in golf, but I'm not sure how far I can go on this pathway," Yin said.。

"Needless to say, it is a choice with complications for me to be an athlete in this field, but the only thing I can ensure is that I will keep it up no matter what results I get." Enditem。
