United Nations Secretary-General Antonio Guterres has called for $35bn more, including $15bn in the next three months, for the World Health Organization’s (WHO) “ACT Accelerator” programme to back vaccines, treatments and diagnostics against COVID-19.
Some $3bn has been contributed so far, Guterres told an online event, calling it “seed funding” that was less than 10 percent of what the WHO wants for the programme.
Financial support has so far lagged, as nations or governments including the EU, UK, Japan and the US reach bilateral vaccine deals, prompting Guterres and WHO General Director Tedros Adhanom Ghebreyesus to plead to nations to contribute.
AstraZeneca’s pause of an experimental vaccine for the coronavirus after the illness of a participant is a “wake-up call” but should not discourage researchers, the WHO chief scientist has said.

Singapore Airlines (SIA) says it will cut about 4,300 jobs – about 20 percent of the workforce – due to the devastating effect of the coronavirus, and warned any recovery would be “long and fraught with uncertainty”.
SIA is the latest airline to announce massive layoffs as the global aviation industry faces its greatest-ever crisis due to travel restrictions to fight the spread of coronavirus.
The city-state’s flag carrier said about 1,900 positions had already been eliminated in recent months.

AstraZeneca should still know before the end of the year whether its experimental COVID-19 vaccine works, the drugmaker’s Chief Executive Pascal Soriot said, so long as it can resume trials soon.
The British company suspended late-stage trials this week after a participant in the UK reportedly suffered symptoms associated with transverse myelitis, a rare spinal inflammatory disorder.
Serum Institute of India has put trials of AstraZeneca’s COVID-19 vaccine candidate on hold until the British drugmaker restarts the trials.

British Prime Minister Boris Johnson announced at a coronavirus briefing on Wednesday a “moonshot plan” for “COVID-free passports” that would allow people who test negative to return to normal life.
The plan involves mass testing – with results returned within about 20 minutes – a negative result allowing entry to venues such as theatres or football stadiums among others.
Reacting to Johnson’s claims, Dr Chaand Nagpaul of the British Medical Association said there were “huge problems” with lab capacity, and he was unsure whether the PM’s strategy could work.
Australia’s conservative government clashed with state legislators over how fast to relax coronavirus restrictions, as the number of new COVID-19 cases showed a steady decline.
In March, Australia created a national cabinet of federal, state and territory leaders to coordinate measures to control the disease, such as closing borders, suspending schools and closing businesses.
This helped Australia record far fewer infections and deaths than many other developed nations. Divisions in the national cabinet are emerging at a time when infection rates are coming down.
South Korea’s new coronavirus cases have stayed below 200 for an eighth day, suggesting the recent resurgence is slowing amid stringent distancing rules.

Hello, this is Usaid Siddiqui in Doha taking over from my colleague Kate Mayberry.
A study published in Nature says the US has a “substantial underestimation” of coronavirus cases because of its restrictions on testing, and the actual figure could be three to 20 times higher.
The US mainly tests people with moderate to severe symptoms so those with mild or no symptoms are rarely tested, noted the researchers, led by Sean Wu of the Division of Epidemiology and Biostatistics at the University of California, Berkeley.
The team analysed testing rates in each state between February and April and corrected for incomplete and inaccurate tests. They found discrepancies between states, with higher rates of testing in the northwest and northeast, and lower levels in the south and Midwest.
Singapore is to start distributing its TraceTogether token, a contact-tracing device, from Monday. Use of the token is not mandatory, but it is free of charge to anyone who wants one.
The city-state already has a contact-tracing app, but the token, which also uses Bluetooth to track movements, does not need a smartphone. Initial distribution will be in areas with a large number of older people.

In a room inside a hillside Taoist monastery in China’s Shandong province is a collection of 558 memorial tablets inscribed with the names and home towns of people who died after contracting the coronavirus or while battling the pandemic.
Some, like Li Wenliang, are household names in China. Others, like Liu Hewei, are not.
“No matter what religion or beliefs they hold, their spirit deserves to be passed on. In fact, they live on in our hearts,” said Taoist priest Liang Xingyang, who started the collection on January 29, shortly after Chinese authorities announced that the virus could pass between humans.
A preliminary study has found headaches, confusion and delirium experienced by some COVID-19 patients could be the result of the coronavirus directly invading the brain.
According to the paper, which was led by Yale immunologist Akiko Iwasaki, the virus is able to replicate inside the brain, and its presence starves nearby brain cells of oxygen. The prevalence of this is not yet clear.
S Andrew Josephson, chair of the neurology department at the University of California, San Francisco, said “understanding whether or not there is direct viral involvement of the brain is extraordinarily important.” But he added that he would remain cautious until the paper underwent peer review.
Australia’s health minister says the state of Victoria should consider lifting a nighttime curfew in Melbourne if it has not been imposed for health reasons.
The state has been under pressure over the 8pm to 5am (10:00 to 19:00 GMT) curfew – one of a number of strict measures imposed to stifle a surge in coronavirus that emerged in early August – since the chief health officer told local radio he had not recommended the policy.
State premier Daniel Andrews has said the curfew was introduced to make it easier for police to enforce the other lockdown measures, which remain in force until September 28. The curfew has been fuelling a lot of discussion on social media.
The only other places I'm aware have used curfews are those with crisis-level epidemics (New York, Spain at their peak) and autocratic governments in Africa https://t.co/dvgLhS21Yz

"This is an unprecedented assault on civil liberties.
"If it's necessary … fair enough. But where's the evidence? Where's the advice it would be?"
Neil Mitchell understands police weren't consulted before the introduction of the curfew. https://t.co/eiTxm4D8Vh

I know the curfew in Melbourne has stopped me from making an 11pm Maccas run at least twice in the last 6 weeks.
So that's good… right?

In the six months since the coronavirus pandemic was declared, the most vulnerable children have disproportionately missed out on access to education, healthcare, and food, and suffered the greatest protection risks, according to a new global survey by Save the Children.
The survey, based on the experience of 25,000 children and their caregivers across 37 countries, found:
“To protect an entire generation of children from losing out on a healthy and stable future, the world needs to urgently step up with debt relief for low-income countries and fragile states, so they can invest in the lives of their children,” Inger Ashing, Save the Children’s CEO, said in a statement.
Jakarta governor Anies Baswedan says the Indonesian capital will head back into lockdown as it steps up efforts to tackle what he said was an “emergency – more pressing than the start of the pandemic” because modelling showed the capital’s hospitals would be overwhelmed by September 17 if no action was taken
From Monday, all offices will be closed except for businesses in 11 “essential” fields. Entertainment venues will be closed and all gatherings banned. Religious events will only be allowed at the village level for people who live in the area, he added.
Indonesia has recorded 8,336 deaths from coronavirus, the most in Southeast Asia.
