Coronavirus: Oxford vaccine effective in monkeys, heading for mass production in India

  • Six animals inoculated with vaccine candidate then exposed to virus did not catch Covid-19 after 28 days
  • Up to 60 million doses could be produced by Serum Institute of India this year

A leading candidate for a Covid-19 vaccine has shown promising results in animal trials, and is expected to see mass production in India within months.

The Serum Institute of India, the world’s largest maker of vaccines by volume, said on Tuesday that it plans this year to produce up to 60 million doses of a potential vaccine developed by the University of Oxford, which is under clinical trial in Britain.

While the vaccine candidate, called “ChAdOx1 nCoV-19”, is yet to be proven to work against Covid-19, Serum decided to start manufacturing it as it had shown success in animal trials and had progressed to tests on humans, Serum Chief Executive Adar Poonawalla said.

Six rhesus macaque monkeys were inoculated with the vaccine candidate at the National Institutes of Health’s Rocky Mountain Laboratory in Montana last month, according to The New York Times.

The subjects were exposed afterwards to large quantities of the novel coronavirus, but all six remained healthy after more than 28 days, the newspaper reported, citing researcher Vincent Munster, who conducted the test.

More than 3 million people have been reported to be infected globally and over 210,000 have died from Covid-19, the respiratory disease caused by the coronavirus.

“They are a bunch of very qualified, great scientists [at Oxford] … That’s why we said we will go with this and that’s why we are confident,” Poonawalla told Reuters in a phone interview.

“Being a private limited company, not accountable to public investors or bankers, I can take a little risk and sideline some of the other commercial products and projects that I had planned in my existing facility,” Poonawalla said.

As many as 100 potential Covid-19 candidate vaccines are now under development by biotech and research teams around the world, and at least five of these are in preliminary testing in people in what are known as phase one clinical trials.

Poonawalla said he hoped trials of the Oxford vaccine, due to finish in about September, would be successful. Oxford scientists said last week the main focus of initial tests was to ascertain not only whether the vaccine worked but that it induced good immune responses and no unacceptable side effects.

Serum, owned by the Indian billionaire Cyrus Poonawalla, plans to make the vaccine at its two manufacturing plants in the western city of Pune, aiming to produce up to 400 million doses next year if all goes well, Poonawalla said.

“A majority of the vaccine, at least initially, would have to go to our countrymen before it goes abroad,” he said, adding that Serum would leave it to the Indian government to decide which countries would get how much of the vaccine and when.

Serum envisages a price of 1,000 rupees (US$14.70) per vaccine, but governments would give it to people without charge, he said.

He said Prime Minister Narendra Modi’s office was “very closely” involved in the vaccine production and the company is hoping the government will help foot the cost of making it.

Over roughly the next five months, Serum will spend some 300 million to 400 million rupees (US$4.4 million to US$5.9 million) on making around 3-5 million doses per month, he said. “[The government] are very happy to share some risk and fund something with us, but we haven’t really pencilled anything down yet,” Poonawalla said.

Serum has also partnered with the US biotech firm Codagenix and Austria’s Themis on two other Covid-19 vaccine candidates and plans to announce a fourth alliance in a couple of weeks, he said.

Serum’s board last week also agreed to invest roughly 6 billion rupees (US$8.8 billion) on making a new manufacturing unit to solely produce coronavirus vaccines, Poonawalla said.

Wuhan declared free of Covid-19 as last patients leave hospital after months-long struggle against coronavirus

  • City at centre of outbreak finally able to declare itself clear of disease after months in lockdown and thousands of deaths
  • Risk of infection remains, however, with some patients testing positive for coronavirus that causes disease without showing symptoms

The city of Wuhan, the initial epicentre of the coronavirus pandemic, no longer has any Covid-19 patients in hospital after the last 12 were discharged on Sunday.

Their release ended a four-month nightmare for the city, where the disease was first detected in December. The number of patients being treated for Covid-19, the disease caused by a new coronavirus, peaked on February 18 at 38,020 – nearly 10,000 of whom were in severe or critical condition.

“With the joint efforts of Wuhan and the national medical aid given to Hubei province, all cases of Covid-19 in Wuhan were cleared as of April 26,” Mi Feng, a spokesman for the National Health Commission said on Sunday afternoon.

The announcement came only one day after the city discharged the last patient who had been in a severe condition. That patient also was the last severe case in Hubei province.

The last patient discharged from Wuhan Chest Hospital, a 77-year-old man surnamed Ding, twice tested negative for Sars-CoV-2, the virus that causes Covid-19, and was released at noon on Sunday.

“I missed my family so much!” Ding told Changjing Daily.

Another unidentified patient exclaimed as he left the hospital: “The air outside is so fresh! The weather is so good today!”

Wuhan faced a long journey to bring its patient count down to zero.

The city of 11 million, the capital of Hubei province and a transport hub for central China, was put under a strict lockdown on January 23 that barred anyone from entering or exiting the city without official approval for 76 days until it was officially lifted on April 8.

Residents were ordered to stay in their apartments as the city stopped public transport and banned private cars from city streets. As the epidemic worsened, more than 42,000 medical staff from across the country were sent to the city and to Hubei province to help ease the burden on the local health care system.

Wuhan was the hardest hit city in China, accounting for 50,333 of the 82,827 locally transmitted Covid-19 cases recorded in China. More than 4,600 died in the country from the disease.

On March 13, the city reported for the first time that there were no new suspected cases of the infection, and five days later there were no confirmed cases.

The number of discharged patients bottomed out at 39.1 per cent at the end of February, gradually climbing to 92.2 per cent by last Thursday.

“Having the patients in the hospital cleared on April 26 marks a major achievement for the city’s Covid-19 treatment,” the Wuhan Health Commission said in a statement.

However, having no severe cases in hospital does not mean all the discharged patients will require no further treatment as they may still need further care.

“Clearing all the severe cases marks a decisive victory for the battle to safeguard Wuhan,” health minister Ma Xiaowei told state broadcaster China Central Television on Saturday.

“Some patients who have other conditions are being treated in specialised hospitals. It has been properly arranged.”

Ten patients aged between 42 and 85 who have been declared coronavirus-free are still in intensive care at the city’s Tongji Hospital where they are being treated for kidney problems and other complications arising from Covid-19. Some still need ventilators to help them breathe.

These 10 patients are under 24-hour care, with 190 nurses on four-hour rotations. There are other patients in a similar condition in two other hospitals in Wuhan, according to the Hubei Broadcasting and Television Network.

However, the discharge of the last batch of Covid-19 patients does not mean that the risk of infection is gone.

The city reported 20 new cases of people testing positive for Sars-CoV-2, the official name for the coronavirus that causes the disease, but who do not yet show symptoms.

There are 535 such carriers under medical observation. Past data shows some of these asymptomatic carriers will develop symptoms, and so will be counted as Covid-19 patients under China’s diagnosis and treatment plan.

China’s coronavirus infection curve has flattened out with about 694 imported cases of Covid-19 on top of about 800 locally transmitted ones now under treatment.

The national health commission spokesman warned that people still need to be on high alert as the virus is continuing to spread around the globe, with no sign yet of a slowdown.

“[We] must not drop our guard and loosen up. [We] must discover cases in time and deal with them quickly,” Mi said, citing the continued pressure from cases imported by people returning from overseas.

“The next step will be to implement the requirements of the central government and continue to guard against imported cases and a rebound of domestic transmitted cases.”
