Moscow, Jul 13: Russia has become the first nation to complete clinical trials of a COVID-19 vaccine on humans. Chief researcher Elena Smolyarchuk, who heads the Center for Clinical Research on Medications at Sechenov University, told Russian news agency TASS on Sunday that the human trials for the vaccine have been completed at the university and the volunteers will be discharged soon.

"The research has been completed and it proved that the vaccine is safe. The volunteers will be discharged on July 15 and July 20," Smolyarchuk was quoted as saying in the report.

Though the results have been favourable with respect to the medication’s effectiveness, no further information was provided on when this vaccine would enter commercial production stage.

Russia had allowed clinical trials of two forms of a potential COVID-19 vaccine developed by the Gamaleya National Research Center for Epidemiology and Microbiology on June 18.

The first vaccine, in the form of a solution for intramuscular administration, was carried out at the Burdenko Military Hospital.

Another vaccine, in the form of a powder for the preparation of a solution for intramuscular administration, was carried out at Sechenov First Moscow State Medical University.

The first stage of research on the vaccine at Sechenov University involved a group of 18 volunteers and the second group involved 20 volunteers.

After vaccination, all volunteers were expected to remain in isolation in a hospital for 28 days.

Earlier, results of the COVID-19 vaccine tests performed on a group of volunteers in Russia showed that they were developing immunity to the coronavirus.

"The data obtained by the Gamalei National Research Center for Epidemiology and Microbiology, proves that volunteers of the first and second groups are forming an immune response after injections of the vaccine against the coronavirus," according to an earlier statement from the Russian Defense Ministry.

Russia has reported 719,449 cases and 11,188 deaths to date.

There are at least 21 vaccines currently under key trials, according to the World Health Organisation (WHO).

The overall number of global COVID-19 cases crossed 12.9 million, while the deaths have increased to more than 5,69,000, according to Johns Hopkins University in the US.

As of Monday morning, the total number of cases stood at 1,29,10,357, while the fatalities rose to 5,69,128.

The US accounted for the world's highest number of infections at over 33 lakh. Brazil came in the second place with over 18 lakh infections. India is third worst affected with over 8.7 lakh people reported to have COVID-19.

Washington, Jun 30: Indian-American Medha Raj has been named by Democratic presidential candidate Joe Biden as his digital chief of staff, a key role in his election campaigns which are entirely going virtual due to the Covid-19 pandemic in the US.

In this capacity, Raj will work across all facets of the digital department to streamline and coordinate how to maximise the impact of its digital outputs, the Biden campaign said.

“Excited to share that I've joined Joe Biden's campaign as the Digital Chief of Staff. 130 days to the election and we're not going to waste a minute!” she said on LinkedIn.

Raj comes from Pete Buttigieg's campaign, who has now endorsed Biden.

The news was first reported by CNN, which the news channel said is part of the efforts of the Biden campaign to adapt to an almost entirely virtual campaign trail brought on by the coronavirus pandemic.

The US is the hardest-hit country by the coronavirus pandemic, with more than 2.64 million official cases and over 128,000 deaths.

According to CNN, Clarke Humphrey, who previously worked on Hillary Clinton's 2016 campaign, will act as the Biden campaign's new deputy digital director for the grassroots fundraising.

Jose Nunez is the campaign's new digital organising director.

He is from the Kamala Harris' campaign. Christian Tom is the new director of digital partnerships. Over the past few months, Biden has been relying more and more on digital campaigning and raising funds virtually.

A graduate in international politics from Georgetown University, Raj has earned her MBA from Stanford University.

Biden, 77, is challenging the 74-year-old Republican incumbent President Donald Trump in the November 3 presidential elections.

Former US vice president Biden would formally accept his Democratic presidential nomination at the party’s scaled back convention in Wisconsin’s Milwaukee city on August 20.

In view of the coronavirus pandemic, the Democratic National Convention Committee (DNCC) on Wednesday announced its convention plan to broadcast from Milwaukee and across the nation to reach out to all Americans.

According to some of the latest opinion polls, Biden is leading by more than eight percentage points over Trump.

Washington, May 27: Most viruses and other germs do not spread easily on flights, the US Center for Disease Control and Prevention has said in its COVID-19 guidelines which do not recommend following social distancing between two passengers inside a plane or keeping the middle seat unoccupied.

As a result of coronavirus pandemic, air traffic inside the US has come to a near halt. Air traffic is said to be down to about 90 per cent. For all travellers coming from overseas, the Center for Disease Control and Prevention (CDC) has recommended 14 days quarantine.

"Most viruses and other germs do not spread easily on flights because of how air circulates and is filtered on aeroplanes," the CDC has said in its set of COVID-19 guidelines for air travellers.

However, it noted that the air travellers were not risk-free especially in the time of the coronavirus pandemic and recommended Americans to avoid travel as far as possible.

"Air travel requires spending time in security lines and airport terminals, which can bring you in close contact with other people and frequently touched surfaces," it said.

"Social distancing is difficult on crowded flights, and you may have to sit near others (within six feet), sometimes for hours. This may increase your risk for exposure to the virus that causes COVID-19," the CDC said.

But instead of recommended social distancing inside commercial planes, the CDC has advised a series of preventive and hygienic measures to be taken by the airlines pilot and crew to prevent the spread of coronavirus.

The US Department of Transportation and Federal Aviation Administration in its latest safety alerts for operators on May 11 said that air carriers and crews conducting flight operations having a nexus to the US, including both domestic and foreign air carriers, should follow CDC's occupational health and safety guidance.

The CDC issued its guidelines in first guidelines for the airlines and airline crew on March and again in May.

The CDC, which has issued an exhaustive social guideline measures in various sections, is silent on keeping the middle seat of a plane unoccupied so as to maintain the six feet distance between two passengers.

It calls for the plane crew to report to the CDC a traveller with specific COVID-19 symptoms like fever, persistent cough, difficulty in breathing and appearing unwell.

Asking the airlines and cabin crew to review infection control guidelines for cabin crew, the CDC recommends several measures for cabin crew to protect themselves and others, manage a sick traveller, clean contaminated areas, and take actions after a flight.

Prominent among them include washing hands often with soap and water for at least 20 seconds, particularly after assisting sick travellers or touching potentially contaminated body fluids or surfaces and use of alcohol-based hand sanitizer (containing at least 60 per cent alcohol) if soap and water are not available.

Airlines should consider providing alcohol-based hand sanitizer to cabin and flight crews for their personal use, it said.

The CDC guidelines do not recommend following social distancing inside a plane between two passengers or keeping the middle seat unoccupied. But it asks to minimise contact between passengers and cabin crew and the sick person.

"If possible, separate the sick person from others (by a distance of 2 meters or 6 feet, ideally) and designate one crew member to serve the sick person. Offer a facemask, if available and if the sick person can tolerate it. If a facemask is not available or cannot be tolerated, ask the sick person to cover their mouth and nose with tissues when coughing or sneezing," said the CDC guidelines.

If no symptomatic passengers were identified during or immediately after the flight, the CDC recommends airlines to follow routine operating procedures for cleaning aircraft, managing solid waste, and wearing PPE.

"If symptomatic passengers are identified during or immediately after the flight, routine cleaning procedures should be followed, and enhanced cleaning procedures should also be used," it said.

Clean porous (soft) surfaces (e.g, cloth seats, cloth seat belts) at the seat of the symptomatic passengers and within 6 feet of the symptomatic passengers in all directions, it added.
