China's Nobel laureate Liu Xiaobo dies aged 61

Russia boasts that it's about to become the first country to approve a Covid-19 vaccine, with mass vaccinations planned as early as October using shots that are yet to complete clinical trials -- and scientists worldwide are sounding the alarm that the headlong rush could backfire.

Moscow sees a Sputnik-like propaganda victory, recalling the Soviet Union's launch of the world's first satellite in 1957.

But the experimental Covid-19 shots began first-in-human testing on a few dozen people less than two months ago, and there's no published scientific evidence yet backing Russia's late entry to the global vaccine race, much less explaining why it should be considered a front-runner.

“I'm worried that Russia is cutting corners so that the vaccine that will come out may be not just ineffective, but also unsafe,” said Lawrence Gostin, a global public health law expert at Georgetown University. “It doesn't work that way... Trials come first. That's really important.”

According to Kirill Dmitriev, head of Russia's Direct Investment Fund that bankrolled the effort, a vaccine developed by the Gamaleya research institute in Moscow may be approved in days, before scientists complete what's called a Phase 3 study.

That final-stage study, usually involving tens of thousands of people, is the only way to prove if an experimental vaccine is safe and really works.

Health Minister Mikhail Murashko said members of “risk groups,” such as medical workers, may be offered the vaccine this month.

He didn't clarify whether they would be part of the Phase 3 study that is said to be completed after the vaccine receives “conditional approval.”

Deputy Prime Minister Tatyana Golikova promised to start “industrial production” in September, and Murashko said mass vaccination may begin as early as October.

Dr Anthony Fauci, the top US infectious disease specialist, questioned the fast-track approach last week.

“I do hope that the Chinese and the Russians are actually testing a vaccine before they are administering the vaccine to anyone, because claims of having a vaccine ready to distribute before you do testing I think is problematic at best," he said.

Questions about this vaccine candidate come after the US, Britain and Canada last month accused Russia of using hackers to steal vaccine research from Western labs.

Delivering a vaccine first is a matter of national prestige for the Kremlin as it tries to assert the image of Russia as a global power capable of competing with the US and China.

The notion of being “the first in the world” dominated state news coverage of the effort, with government officials praising reports of the first-step testing.

In April, President Vladimir Putin ordered state officials to shorten the time of clinical trials for a variety of drugs, including potential coronavirus vaccines.

According to Russia's Association of Clinical Trials Organizations, the order set “an unattainable bar” for scientists who, as a result, "joined in on the mad race, hoping to please those at power.”

The association first raised concern in late May, when professor Alexander Gintsburg, head of the Gamaleya institute, said he and other researchers tried the vaccine on themselves.

The move was a “crude violation of the very foundations of clinical research, Russian law and universally accepted international regulations" the group said in an open letter to the government, urging scientists and health officials to adhere to clinical research standards.

But a month later, the Health Ministry authorized clinical trials of the Gamaleya product, with what appeared to be another ethical issue.

Human studies started June 17 among 76 volunteers. Half were injected with a vaccine in liquid form and the other half with a vaccine that came as soluble powder.

Some in the first half were recruited from the military, which raised concerns that servicemen may have been pressured to participate.

Some experts said their desire to perform well would affect the findings. “It's no coincidence media reports we see about the trials among the military said no one had any side effects, while the (other group) reported some," said Vasily Vlassov, a public health expert with Moscow's Higher School of Economics.

As the trials were declared completed and looming regulatory approval was announced last week, questions arose about the vaccine's safety and effectiveness.

Government assurances the drug produced the desired immune response and caused no significant side effects were hardly convincing without published scientific data describing the findings.

The World Health Organization said all vaccine candidates should go through full stages of testing before being rolled out.

“There are established practices and there are guidelines out,” WHO spokesman Christian Lindmeier said Tuesday.

“Between finding or having a clue of maybe having a vaccine that works, and having gone through all the stages, is a big difference.”

Offering an unsafe compound to medical workers on the front lines of the outbreak could make things worse, Georgetown's Gostin said, adding: “What if the vaccine started killing them or making them very ill?”

Vaccines that are not properly tested can cause harm in many ways — from a negative impact on health to creating a false sense of security or undermining trust in vaccinations, said Thomas Bollyky, director of the global health program at the Council on Foreign Relations. 

Washington, Aug 4: US President Donald Trump gave popular Chinese-owned video app TikTok six weeks to sell its US operations to an American company, saying Monday it would be "out of business" otherwise, and that the government wanted a financial benefit from the deal.

"It's got to be an American company... it's got to be owned here," Trump said. "We don't want to have any problem with security."

Trump said that Microsoft was in talks to buy TikTok, which has as many as one billion worldwide users who make quirky 60-second videos with its smartphone app.

But US officials say the app constitutes a national security risk because it could share millions of Americans' personal data with Chinese intelligence.

Trump gave the company's Chinese parent ByteDance until mid-September to strike a deal.

"I set a date of around September 15, at which point it's going to be out of business in the United States," he said.

Whatever the price is, he said, "the United States should get a very large percentage of that price because we're making it possible."

Trump compared the demand for a piece of the pie to a landlord demanding under-the-table "key money" from a new tenant, a practice widely illegal including in New York, where the billionaire president built his real estate empire.

"TikTok is a big success, but a big portion of it is in the country," he said. "I think it's very fair."

But Trump also threw a surprise new condition in any deal, saying the sale of TikTok's US business would have to result in a significant payout to the US Treasury for initiating it.

"A very substantial portion of that price is going to have to come into the Treasury of the United States, because we're making it possible for this deal to happen," Trump told reporters.

"They don't have any rights unless we give it to them," he said.

Sell or shut down

The pressure for a sale of TikTok's US and international business, based in Los Angeles, left the company and ByteDance facing tough decisions.

Trump has made TikTok the latest front in the ongoing political and trade battles between Washington and Beijing.

The app has been under formal investigation on US national security grounds because it collects large amounts of personal data on all its users and is legally bound to share that with authorities in Beijing if they demand it.

Both its huge user base and its algorithm for collecting data make it hugely valuable.

But being forced by the US government to sell at least its US business or be shut down -- and to then split the sale price with the US Treasury as Trump is demanding -- was an almost unheard-of tactic.

Shutting down could force users to switch to competitors, and many content creators are already encouraging followers to follow them on other social media platforms.

"The most obvious beneficiaries are Snapchat, Facebook and Twitter, with Snapchat likely being the biggest beneficiary," said investment analysts at Lightshed Partners.

Earlier Monday, ByteDance founder Zhang Yiming acknowledged the hefty pressure and said in a letter to staff, reported by Chinese media, that they were working around-the-clock "for the best outcome."

"We have always been committed to ensuring user data security, as well as the platform neutrality and transparency," Zhang said.

However, he said, the company faces "mounting complexities across the geopolitical landscape and significant external pressure."

He said the company must confront the challenge from the United States, though "without giving up exploring any possibilities."

According to Britain's The Sun newspaper Monday, as a possible consequence of the pressure, ByteDance is planning to relocate TikTok's global operations to Britain.

Pushing back

China's foreign ministry pushed back Monday, calling Washington hypocritical for demanding TikTok be sold.

"The US is using an abused concept of national security and, without providing any evidence, is making presumptions of guilt and issuing threats to relevant companies," said spokesman Wang Wenbin.

"This goes against the principle of market economy and exposes the hypocrisy and typical double standards of the US in upholding so-called fairness and freedom," he added.
