Italian researchers have claimed that they have successfully developed a vaccine to contain coronavirus (COVID-19) which is likely to work on humans, a report said.

Luigi Aurisicchio, CEO of Takis, the firm developing the medication, said that a coronavirus candidate vaccine has neutralised the virus in human cells for the first time, the Arab News reported.

"This is the most advanced stage of testing of a candidate vaccine created in Italy. Human tests are expected after this summer," Aurisicchio was quoted as saying to Italian news agency ANSA.

"According to the Spallanzani Hospital, as far as we know we are the first in the world so far to have demonstrated neutralisation of the coronavirus by a vaccine. We expect this to happen in humans too," he added.

The researchers experimented with the vaccine on mice that had successfully developed antibodies that blocked the virus from infecting the cells. They further observed that the five vaccine candidates generated a large number of antibodies, and selected two with the best results.

All of the vaccine candidates currently being developed are based on the genetic material of DNA protein "spike", the molecular tip used by the coronavirus to enter human cells.

They are injected with the so-called "electroporation" technique, which consists of an intramuscular injection followed by a brief electrical impulse, helping the vaccine break into the cells and activating the immune system, the report said.

Researchers believe that this makes their vaccine particularly effective for generating functional antibodies against the "spike" protein, in particular in the lung cells, which are the most vulnerable to coronavirus.

"We are working hard for a vaccine coming from Italian research, with an all-Italian and innovative technology, tested in Italy and made available to everyone," Aurisicchio was quoted by the Arab News report.

"In order to reach this goal, we need the support of national and international institutions and partners who may help us speed up the process," he noted.

The total number of COVID-19 infections, fatalities and recoveries since the pandemic began has risen to 213,013 in the country.

Washington, Mar 1: Beginning April 1, Indians wishing to immigrate to America will now have to pay an additional $50,000 for the EB-5 or the US investor visa, a media report said.

Although, this additional tax would impact all visa categories, it will predominantly create a barrier for people investing in the EB-5 visa programme, the American Bazaar daily said in the report on Friday.

In 2019, the EB-5 investor visa programme, for the first time since the 1990's, increased the minimum investment amount to $900,000.

With this increase in minimum investment, the new 5 per cent additional tax would mean that applicants would have to pay the extra $50,000, when they move money to an escrow account in the US to fulfil their application criterion.

"The changes to the tax on remittances is a reminder to Indians to carefully plan their tax position before making the move to the US," the American Bazaar quoted Mark Davies, Global Chairman, Davies & Associates LLC, as saying.

"People seeking to emigrate who do not wish to pay this tax at source and rather account for it later may wish to move their money ahead of the new rules coming into effect.

"It is possible to pre-emptively move money into an escrow account in the US until such a time as they are ready to proceed with emigration process," he added.

Washington, May 20: Once dubbed as historic by him, US President Donald Trump on Tuesday said he now feels ‘differently’ about the trade deal he signed with China earlier this year.

He said this while once again venting out his frustration with the Beijing leadership, accusing it of letting coronavirus spread.

Till Tuesday, over 92,000 Americans have died and 1.5 million tested positive for coronavirus that has globally killed around 320,000 people.

The US and China had signed a deal in January to end their 22-month-long trade war during which the two countries slapped tit-for-tat tariff hikes on products worth nearly half a trillion USD.

Under it, Beijing agreed to increase its purchase of US goods by USD 200 billion in 2020-2021.

“I feel differently now about that deal than I did three months ago,” Trump told reporters during a Cabinet meeting at the White House.

“We will see what all happens, but it's been a very disappointing situation. A very disappointing thing happened with China because the plague flowed in and that wasn't supposed to happen and it could have been stopped," he said.

Trump said he was very excited when the trade deal with China was signed.

“But once the virus came in, once the plague, as I called it, came in, I said how did they let that happen? And how come it didn't go into other sections of China? Why did they block it from leaving Wuhan? But they didn't block it from going to the rest of the world, including the United States. Why is that? Beijing doesn't have it. Other places don't have it,” he said.

Trump did not respond to questions on retaliation against China.

Meanwhile, top American senators continued to press the administration that rules of engagement with China needs to change post-coronavirus.

“As we know, they unleashed this virus on America and the world with their classic communist cover-up, deception, continued propaganda campaign, costing now over 90,000 American lives, 35 million Americans losing their jobs so far,” Senator Martha McSally said during a Congressional hearing.

“We don’t know who patient zero is, they destroyed samples, they silenced doctors, they kicked out journalists, they impacted international travel to seed this and their reckless behaviour continues to be the root of all this,” she said.

As a result of coronavirus, the American economy has been thrown into recession; more than 36 million people have lost their job – the worst ever after last century’s great depression.

Many of the US states have now started opening up, after taking necessary precautions.

By conservative estimates, it will take several quarters for the economy to be back on track.

Trump in the last a few weeks has exuded confidence that the economy will be back on track next year.
