近期陕西新冠疫苗充足 序贯加强接种既可优势互补也可减少副反应******

近日我省已启动新冠疫苗序贯加强针接种,让加强免疫多了一种选择。据陕西省疾控中心专家介绍,近期我省新冠疫苗供应较为充足,建议符合接种条件的人群“应接尽接”,建立全省免疫屏障。

陕西省疾控中心专家介绍说,按照技术路线区分,我国目前批准使用的新冠疫苗共有三类,分别是由国药中生北京公司、北京科兴公司、国药中生武汉公司等生产的灭活疫苗;天津康希诺公司生产的腺病毒载体疫苗;安徽智飞龙科马公司生产的重组蛋白疫苗。

日前启动的序贯加强免疫,针对的是接种灭活疫苗的群体。简单来说,就是“18 2 6 1”,即18岁以上人群,完成2针灭活疫苗接种,满6个月后,再加强接种1针。现在,这个“1”多了一种选择,可以继续打同类的灭活疫苗,也可以打另外两类疫苗中的一种。

据介绍,序贯加强免疫指的是采用与基础免疫不同的技术路线的疫苗,进行加强免疫接种。比如之前打的两针灭活疫苗,加强针继续选择灭活疫苗,叫做同源加强免疫;如果选择的是腺病毒疫苗或者重组蛋白疫苗进行加强免疫,叫做序贯加强免疫。

序贯加强免疫接种有两个优点。一个是不同疫苗之间可以优势互补,对于激发免疫系统来说,有更好的效果。另外一点,对于部分人来说,可以减少一些副反应,不同体质的人对某一种疫苗副反应比严重,那么在加强免疫的时候换一种疫苗,副反应可能就减轻了。

需要注意的是,“同源加强免疫”和“序贯加强免疫”,二选一就可以,如果此前已经使用灭活疫苗完成第3针加强接种的,不需要重复接种。另外,从我省去年12月发生的本土疫情看,接种疫苗病例中出现危重症占比1.09%,而未接种疫苗病例中出现危重症病例则占到11.21%,出现危重症风险较接种疫苗高10倍以上,充分说明疫苗接种对于预防危重症病例有效。

China Focus: "Lighthouse factory" leads the way in China's smart manufacturing******

by Xinhua writers Ye Ting, Zhang Yiyi

BEIJING, Oct. 19 (Xinhua) -- Few operators are needed at the Sany Group's Beijing Rotary Drilling Rig Plant, as industrial robots are the leading employees when it comes to assembling machinery.

The smart factory, located in Changping District of the Chinese capital, was in September added to the World Economic Forum's Global Lighthouse Network, which recognizes factories showing leadership in the Fourth Industrial Revolution.

Notably, the factory in Beijing is the first heavy industry enterprise to be added to the list globally.

With a workshop area of four hectares, the futuristic plant is well equipped with 12 automated production lines and 150 robots.

Human workers have also been trained as technicians who can operate the robots directly, according to Dong Mingkai, dean of Sany's intelligent manufacturing research institute.

The factory has deployed a new manufacturing model with advanced human-machine collaboration automation, artificial intelligence and Internet of Things technologies.

The upgrade has served as a boost for production efficiency and product quality, as these innovations have managed to increase labor productivity by 85 percent and slash production lead time by 77 percent, accelerating from almost a month to just a week.

On the automatic assembly line for small and medium-sized parts, Automatic Guided Vehicle (AGV) and industrial robots connected to the 5G network can move freely on the ground. Together with truss manipulators, the devices are able to position, grasp and assemble machinery parts in an orderly manner.

Nearly 30 model varieties can be produced with the help of robots and core intelligent technologies including laser and visual sensing, working to meet the growing demand for multi-category and small-batch flexible assembly and take a lead in the whole industry, according to Dong.

The factory's number of human workers has decreased from 2,000 to just a fifth of that, while the annual volume of equipment produced has soared from 1,000 to 3,000 units, said Dai Qinghua, director of the Sany Group.

As China promotes green and low-carbon development, and promises to peak carbon emissions before 2030 and achieve carbon neutrality before 2060, the country has reached a consensus to promote a more eco-friendly engineering machinery industry.

The "lighthouse factories" represented by Sany Group's Beijing Rotary Drilling Rig Plant are just one example of Chinese enterprises' unremitting pursuit of high-quality and low-carbon development through digital transformations.

"The plant is resource-saving and eco-friendly, and its demand for and consumption of electricity are obviously decreasing," said Tang Xiuguo, president of Sany Group. He said the power generated by the group's self-sustaining wind power plant has far exceeded the power consumption of all its factories.

"Sany Group will actively explore the applications of new energy to save energy and improve energy efficiency. And existing construction machinery products built with diesel engines and petrochemical energy are expected to rely on electricity in the future," Dai said. Enditem

Action packed Saturday in Premier with Solskjaer's future on the line again******

LONDON, Oct. 29 (Xinhua) -- A lot of the action in the Premier League this weekend is packed into Saturday afternoon with three of the top-four and Manchester United also in action as Ole Gunnar Solskjaer faces a key visit to play Tottenham.

Last weekend's 5-0 humiliation at home to Liverpool put Solskjaer clearly in the firing line, with many expecting him to lose his job after a record defeat and a dreadful display.

The good news for the Norwegian is that central defender Raphael Varane should be available after injury and Victor Lindelof is likely to make way (although Harry Maguire's recent displays mean he is also in the firing line).

Solskjaer also has to find a better balance in midfield, although the suspension for Paul Pobga after last weekend's red card does away with one of his selection dilemmas.

Liverpool will have their confidence sky high and with Mohamed Salah in arguably the best form of his career, they will be favorites to beat Brighton.

The visitors will look to control the ball as much as possible, but the question is whether they will be able to contain Liverpool's energy in attack and the final result may also depend on whether the returning Tariq Lamptey can shackle Salah for 90 minutes.

League leaders Chelsea travel to the north-east where Newcastle United are still looking for their first win of the season. Newcastle caretaker coach Graeme Jones is likely to bring Fabian Schar, Miguel Almiron, Joe Willock back into his team after a valuable point away to Crystal Palace last weekend.

Chelsea are still without the injured Romelu Lukaku and Timo Werner, but their absence didn't cause any problems as Thomas Tuchel's men put seven past Norwich last weekend and although a repeat of that is unlikely, Newcastle will do well to get anything from this game.

Patrick Viera returns to the Ethiad Stadium at the helm of Crystal Palace for what promises to be an entertaining game against Manchester City. The home side still have Ferran Torres out injured, but are otherwise at full strength for a game that Pep Guardiola's men will expect to win with relative comfort.

Consecutive defeats have put the brakes on Brentford's exuberant first season in the Premier League and last weekend saw them lose keeper David Raya to a knee injury opening the door for Alvaro Fernandez to make his league debut.

The former Huesca keeper can expect to be tested in the air when Burnley travel to south-west London still searching for their first victory of the campaign.

It's not been boring since Claudio Ranieri took over at Watford, with a 5-0 defeat to Liverpool followed by Josh King's hat-trick taking them to an incredible 5-2 win away to Everton last weekend. Watford entertain Southampton, who have influential midfielder James Ward Prowse available again after suspension.

Norwich coach Daniel Farke was given a vote of confidence during the week after his side's 7-0 defeat to Chelsea, but if the bottom of the table side fail to beat fourth from bottom Leeds United on Sunday, that bonhomie may start to run out.

Finally, fourth placed West Ham, who knocked Manchester City out of the Carabao Cup in midweek travel to play Aston Villa, who have not won since the middle of September. Enditem
