Rice Bucket Challenge: Water-starved South Asia fills buckets with rice, not ice

Paris, Jul 20: Two coronavirus vaccine candidates have proven safe for humans and produced strong immune reactions among patients involved in separate clinical trials, doctors said on Monday.

The first trial among more than 1,000 adults in Britain found that the vaccine induced "strong antibody and T cell immune responses" against the novel coronavirus.

A separate trial in China involving more than 500 people showed most had developed widespread antibody immune response.

The studies, published in The Lancet medical journal, constitute a major step on the road towards a COVID-19 vaccine that is effective and safe for widespread use.

The authors of the studies said that they encountered few adverse side-effects from the vaccine candidates.

However, they cautioned that more research was needed, particularly among older adults, who are disproportionately at risk of dying of COVID-19.

Co-author Sarah Gilbert from the University of Oxford said the results "hold promise".

"If our vaccine is effective, it is a promising option as these types of vaccine can be manufactured at large scale."

The head of the World Health Organisation on Tuesday warned the novel coronavirus was a "very grave threat" for the world as he opened a conference to combat the epidemic.

"With 99% of cases in China, this remains very much an emergency for that country, but one that holds a very grave threat for the rest of the world," Tedros Adhanom Ghebreyesus said in Geneva.

Some 400 scientists will review how the virus is transmitted and possible vaccines at the two-day forum.

"What matters most is stopping the outbreak and saving lives. With your support, that's what we can do together," Tedros said.

The virus, first identified in China on December 31, has killed more than 1,000 people, infected over 42,000 and reached some 25 countries.

Participants will also discuss the source of the virus, which is thought to have originated in bats and reached humans via another animal such as snakes or pangolins.

There is no specific treatment or vaccine against the virus, which can cause respiratory failure.

Tedros, who has repeatedly urged countries affected to share their data, called for global "solidarity".

"That is especially true in relation to the sharing of samples and sequences. To defeat this outbreak, we need open and equitable sharing, according to the principles of fairness and equity," he said.

"We hope that one of the outcomes of this meeting will be an agreed roadmap for research around which researchers and donors will align," Tedros said.

Several companies and institutes in Australia, China, France, Germany and the United States are racing to develop a vaccine -- a process that normally takes years.

Asked whether scientists from Taiwan would be allowed to take part in this week's Geneva conference, WHO officials said that they would do so but only online -- along with colleagues from other parts of China.

While the WHO does not deal with Taiwan directly and only recognises Beijing, Taiwan was often allowed to attend annual assemblies and sideline meetings as an observer.

But in recent years it has been frozen out as Beijing takes an increasingly combative stance towards democratic Taiwan, which it considers its own territory.

Minneapolis, Jul 23: The former Minneapolis police officer charged with murder in the death of George Floyd was charged Wednesday with multiple felony counts of tax evasion.

Derek Chauvin and his wife, Kellie May Chauvin, were each charged in Washington County with six counts of filing false or fraudulent tax returns for the tax years 2014 through 2019 and three counts of failing to file tax returns for 2016, 2017 and 2018.

Floyd, a Black man who was handcuffed, died May 25 after Chauvin, who is white, pressed his knee against Floyd's neck for nearly eight minutes as Floyd pleaded for air.

Chauvin is charged with second-degree murder, third-degree murder and manslaughter. He and three other officers who were at the scene were fired.

Chauvin is in custody on the charges in the Floyd case. Kellie Chauvin, who filed for divorce after Floyd's death, is not in custody.

Online court records didn't list attorneys for either in the tax evasion case, and calls to Kellie Chauvin did not go through.

Washington County Attorney Pete Orput said the investigation into the Chauvins was started in June by the Minnesota Department of Revenue and Oakdale Police Department.

Authorities allege in the criminal complaints that the Chauvins failed to file income tax returns and pay state income taxes, and that they underreported and underpaid taxes on income they earned from various jobs each year.

The complaints allege that they also failed to pay proper sales tax on a $100,000 BMW purchased in Minnesota in 2018.

Prosecutors say the Chauvins bought the car in Minnetonka but registered it in Florida, where they paid lower sales taxes.
