আন্তর্জাতিক ডেস্ক : নিজেদের তৈরি করোনাভাইরাসের একটি ভ্যাকসিনের অনুমোদন দিয়েছে চীন। এটাই চীনা সরকারের অনুমোদন পাওয়া প্রথম কোভিড-১৯য়ের ভ্যাকসিন। এর আগে রাশিয়া তাদের তৈরি ভ্যাকসিনের অনুমোদন দিয়েছে।

চীনের সংক্রামক রোগ বিশেষজ্ঞ চেন ওয়ের একটি টিম এই ভ্যাকসিন নিয়ে কাজ করেছে। প্রথম দু’টি ধাপে পরীক্ষামূলক প্রয়োগের পর এই ভ্যাকসিনের সফলতার পরই চীন সরকার এই ভ্যাকসিনের অনুমোদন দিল।

চায়না গ্লোবাল টেলিভিশন নেটওয়ার্কের (সিজিটিএন) এক টুইট বার্তায় দেশটির প্রথম ভ্যাকসিনের অনুমোদনের বিষয়টি নিশ্চিত করা হয়েছে। সেখানে বলা হয়েছে, দু’টি ধাপেই পরীক্ষামূলক প্রয়োগে এই ভ্যাকসিন নিরাপদ এবং রোগ প্রতিরোধ ক্ষমতা তৈরি করতে সক্ষম হয়েছে।

এদিকে, যুক্তরাষ্ট্রের মেডিকেল অ্যাসোসিয়েশন জার্নালে প্রকাশিত ক্লিনিক্যাল ট্রায়ালের তথ্যের বরাত দিয়ে সিনহুয়া নিউজ এজেন্সি জানিয়েছে, করোনার এই ভ্যাকসিনটি নিরাপদ ও রোগ প্রতিরোধ ক্ষমতা তৈরিতে কার্যকর।

ভ্যাকসিনটি ৩২০ জন স্বেচ্ছাসেবীর দেহে পরীক্ষামূলক প্রয়োগ করা হয়। প্রথম ধাপের ট্রায়ালে ১৮ থেকে ৫৯ বছর বয়সী ৯৬ জন এবং দ্বিতীয় ধাপে ২২৪ জন স্বেচ্ছাসেবক এই ভ্যাকসিন গ্রহণ করেছে।

সিনহুয়ার এক প্রতিবেদনে বলা হয়েছে, পরীক্ষামূলক প্রয়োগের ফলাফলে ভ্যাকসিনটি কার্যকরভাবে স্বেচ্ছাসেবীদের দেহে নিরপেক্ষ অ্যান্টিবডি তৈরি এবং রোগ প্রতিরোধে সক্ষমতা দেখিয়েছে।
গত ৩১ ডিসেম্বর চীনের হুবেই প্রদেশে প্রথম করোনার সংক্রমণ ধরা পড়ে। চীন থেকে এই ভাইরাস এখন পর্যন্ত বিশ্বের ২১৩টি দেশ ও অঞ্চলে তাণ্ডব চালাচ্ছে।

চীন থেকে এই প্রাণঘাতী ভাইরাসের সংক্রমণ শুরু হলেও ইতোমধ্যেই তারা করোনা পরিস্থিতি নিয়ন্ত্রণে আনতে সক্ষম হয়েছে। যুক্তরাষ্ট্র, রাশিয়া, ব্রাজিল, ভারত, স্পেনের মতো দেশগুলোও যখন করোনার সঙ্গে পেরে উঠছে না তখন চীনে সংক্রমণ এখন অনেকটাই নিয়ন্ত্রণে।

ওয়ার্ল্ডোমিটারের পরিসংখ্যান বলছে, চীনে এখন পর্যন্ত করোনায় আক্রান্ত হয়েছে ৮৪ হাজার ৮৪৯ জন। এর মধ্যে মারা গেছে ৪ হাজার ৬৩৪ জন। অপরদিকে সুস্থ হয়ে উঠেছে ৭৯ হাজার ৬০৩ জন। অর্থাৎ আক্রান্তদের মধ্যে অধিকাংশই এখন সুস্থ।

  2. You actually make it seem really easy together with your presentation but I
    find this matter to be actually something that I think I might never understand.

    It sort of feels too complicated and extremely
    vast for me. I am taking a look ahead to your subsequent post,
    I will try to get the hold of it!

  3. Undeniably believe that which you stated.
    Your favorite reason seemed to be on the internet the easiest factor to have in mind of.
    I say to you, I certainly get irked even as folks think about issues that they plainly don’t understand about.

    You controlled to hit the nail upon the top as well as outlined out the entire thing without having side-effects , other people can take
    a signal. Will probably be again to get more. Thank you

  5. Today, I went to the beachfront with my children. I found a sea shell and
    gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She
    put the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear.
    She never wants to go back! LoL I know this is entirely off topic but I had to tell someone!

  6. We’re at university together tetracycline cost canada Aside from the 15-5 drubbing his team received Wednesday, Helton couldn’t have asked for a better way to cap his 17-year career with the Rockies. Owner Dick Monfort awarded Helton a six-year-old horse for his Northern Colorado ranch prior to the game, while heartfelt messages from former colleagues such as Pirates manager Clint Hurdle and Broncos quarterback Peyton Manning trickled across the Jumbotron throughout the night. Hats off to what has been a brilliant career for The Toddfather.

  7. Could you transfer $1000 from my current account to my deposit account? clomid pills for sale in uk The move would make sense for two reasons. First, Quinn likely wouldn’t be active for Sunday’s season opener anyway, since Ryan generally only likes to suit up two quarterbacks. (Those two QBs will be Geno Smith and Matt Simms.) Also, Quinn probably will remain on the roster only until Mark Sanchez is able to return from his shoulder injury.

  8. I’d like a phonecard, please walgreens viagra prices what gets me is that the writer is using examples like The Last of Us as if it's supposed to spark a discussion here. Completely different types of games for different experiences. Then there's this pretending like GTA hasn't evolved over the years. There's just a lack of understanding of the series' nuances in this article that most avid GTA fans can dismiss it. Should have just scrapped the whole thing and rewrote: GTV: I don't get it. If you want to complain about a big dumb game, maybe grab a copy of Duke Nukem Forever or any Saints Row. Leave the quality titles done by truly amazing developers out of your whiney culture piece.

While not easy to intercept and decipher, the ‘terrorist’ messages are unique.

This may buy the president some political wiggle room when it comes to his pick for Fed chair, since he might be able to placate Republicans with one or two “concession” appointments. Every Fed governor gets a permanent voting seat on the policy-setting Federal Open Market Committee.

    Cundiff, a nine-year veteran, is perhaps best known for a 32-yard missed field goal in the 2011 AFC Championship Game as a Raven that sealed a Super Bowl berth for the Patriots. Cundiff has kicked for the Cowboys, Saints (though it was only one attempt), Browns, Ravens and Redskins. In Washington last season, Cundiff struggled, making just 58.3% of his field-goal attempts before the Redskins cut him in October.

    Opposition was vocal. “The so-called Taxi of Tomorrow is a misnomer,” Ethan Gerber, executive director of the Greater New York Taxi Association, which represents fleet owners, told Capital New York. “There is nothing ‘tomorrow’ about it. Let’s call it Taxi of Yesterday. It is not accessible. It is not clean-air. It is a non-accessible, non-hybrid, non-clean air, old-fashioned combustion engine.”

  15. What’s the interest rate on this account? naproxen accord 500 Founded in 1986, Harpoon Brewery is one of the oldest craft breweries in the U.S. The Boston mainstay first introduced its 100 Barrel Series in 2003 to showcase the individual talents of its brewers. This 47th installment of the series is a collaboration of four different Harpoon brewers — Ethan Elston, Jamie Maxwell, Rich Masella and Ryan Thompson, each of whom brewed a saison style-beer but with totally different recipes. The name refers to the blending of the four unique saisons and the various ingredients and yeast strains found within this complex golden ale. Elson’s version incorporates American hops, a Trappist yeast strain, coriander, orange peel and black peppercorn; Maxwell’s is a traditional version with a French saison yeast strain, Bohemian pilsner malt and noble hops; Thompson’s features coriander and white peppercorn; and Masella utilizes New Zealand Pacifica and Motueka hops to give a citrus-tinged hop profile. The result of this grand experiment brings a delightful complexity to the table, featuring spicy overtones backed up with a citrusy hop balance and slightly sour funk of the farmhouse yeasts. The dry aftertaste lingers for several seconds, allowing your taste buds to revisit the aforementioned flavors.

  16. A packet of envelopes where can you buy rogaine in australia I think it’s a huge part of the story of 2012. It turns out that President Obama is the most polarizing president we’ve ever had in American history. But the president who was the most polarizing before that was George W. Bush, and to some extent before that was Bill Clinton, which says to me that this has only partially to do with whoever is in the White House, and more to do with the way the electorate has sorted out red and blue. Those red-blue patterns, I think, are [now] more deeply embedded than they have been ever before. The election on both sides was pitched at finding and turning out the base of each party, as opposed to a real battle over independents or undecideds.

  18. Where’s the nearest cash machine? drillpills.org Seriously? Where do you get the nerve to write such baloney? They overcame nothing. All this game proved was that our 2nd and 3rd string players were better than those of our opponent. Same as last game. The first string offense was horrible. They made one play the whole time they were on the field. Other than that they did nothing. The defense couldn’t stop runs up the middle and Jimmy Smith OMG! Shut down corner, yeah right. Ryan threw three consecutive passes in his direction and he was lost on all three. He couldn’t cover anyone’s grandma. What a wasted first round pick. There is nothing to be excited about so far. Flacco was back to his old pre playoff self, throwing over peoples heads and behind them. Rice ran for 6 yards on 6 carries. Meanwhile the Falcons were running on the Ravens defense the whole time. No time to panic, but the Ravens have a ton of work to do to even be competitive once the real deal starts. Heaven forbid one of The Sun columnists ever tell it like it is.

  21. Is it convenient to talk at the moment? pisos baratos benicarlo alquiler Every mortgage holder is required to have homeowner’s insurance. Sometimes the insurance lapses or gets canceled, often without the homeowner’s knowledge, making it necessary for the mortgage servicer to step in and purchase a form of emergency coverage known as force-placed or lender-placed insurance. Such emergencies have become far more common since the onset of the housing crisis; and because force-placed insurance costs between two and 10 times as much as regular homeowner’s insurance, it can have the perverse effect of driving families into foreclosure or making it harder for them to obtain affordable loan modifications.

And as with children, if they don’t take proper care of them, the dogs should be removed and placed in safer homes. In an ideal world, writes Berns, dogs would be granted personhood, thus banning “puppy mills, laboratory dogs, and dog racing for violating the basic right of self-determinations.”

    The diaries Allen kept through his teenage years give a fantastic picture of this guy who was both incredibly ambitious and incredibly aware of his own intellectual genius. At one point in his diary he writes, “I know I’m a genius. I just don’t know what form that genius is going to take yet.” But on the flip side of that, he was quite shy and not very confident in terms of social interactions. And I found that interesting — to play these great literary figures before they became the great men we know.

If the American team is judged to have longer hitters for example, they may want the fairways tightened and rough made more demanding. Depending on the weather, we can manage that side of things during the spring and early summer. As for the greens, we can set those at pretty much whatever speed is requested. No doubt Paul McGinley will have some views about that.

  35. Best Site Good Work xenical orlistat cheap Conceived as a way of broadcasting text-message style thoughts to small groups, it’s widely believed that Twitter came of age at the South by Southwest Interactive technology festival in 2007, where it placed screens showing tweets around the conference centre. The idea was to both generate buzz and also to demonstrate the usefulness of being able to see what friends or colleagues were up to. Traffic tripled in three days, and today those 60,000 tweets a day are dwarfed by an average of 400m. Where analysts at the time thought Twitter would only ever be a geekish hobby, today it’s indisputably in the mainstream.

Unlike so many of her friends, I’ve never heard her complain about swollen ankles or back pain. When my grandfather was alive, the two of them would go on walks together.

  44. Looking for work uses of tetracycline medicine Here is how one rival exec assessed the Yankees’ situation: “They’ve got a twofold problem. They haven’t been able to develop any power hitters or No. 1-type starting pitchers, and with the way the game is changing now, with the small market clubs all buying out free-agent years with their best young players, the market has gotten thinner and thinner every year. Unlike 2008, when the Yankees essentially bought themselves back to the World Series with the Sabathia, Teixeira and ( A.J. ) Burnett signings, they can’t do that anymore. They’re going to have to trade their way out of this, but their system is very thin on talent too.
