China could start clinical trials for a potential vaccine for the novel coronavirus around late April, an official said Friday.
Public and private researchers around the world have been working to develop treatments and vaccines to combat the COVID-19 virus that first emerged in central China in December.
More than 400 cases of the new coronavirus have been detected in prisons across China, officials said Friday, fuelling concerns about new clusters of the epidemic.
Hubei, the hard-hit central province where the virus emerged late last year, said Friday that 271 cases were reported by its prisons on Thursday, including 220 that had previously not been known to provincial authorities.
More than 2,200 people have died and more than 75,000 have been infected by it in China. Another 11 people died abroad, with some 1,100 infections in around 25 countries.
‘Several research teams were trying different techniques to develop a potential vaccine, and the earliest vaccine is expected to be submitted for clinical trials around late April,’ Xu Nanping, vice science and technology minister, told a press briefing.
China’s vaccine development and research is currently ‘basically in step with other countries’, he added.
The World Health Organization said Tuesday it could take a year or longer for a vaccine to become available.
‘The vaccine could be the long-term because it could take up to 12 to 18 months and this is like preparing for the worst situation,’ said WHO chief Tedros Adhanom Ghebreyesus.
China is currently using five different approaches to develop the vaccine to curb the spread of the virus, said Zeng Yixin, deputy director of China’s National Health Commission
These include using inactivated coronavirus to produce a vaccine, using genetic engineering to mass-produce proteins that could act as antigens for the novel coronavirus or modifying existing vaccines for influenza, Zeng said.
‘At present, some projects have entered the stage of animal testing,’ he said.
Scientists in the US announced Wednesday they had created the first 3D atomic-scale map of the part of the novel coronavirus that attaches to and infects human cells, a critical step toward developing vaccines and treatments.
Local Communist Party newspaper Hubei Daily reported that 230 of the prison cases came from a single facility, the Wuhan Women's Prison, whose warden has been removed for failing to prevent the outbreak, while the other 41 cases were reported at a facility in Shayang county.
Seven guards and 200 inmates also tested positive for the virus at Rencheng prison in eastern Shandong province, the provincial health commission said at a press conference.
Xie Weijun, head of Shandong's justice department, was sacked over the outbreak along with two other provincial prison administration officials and five officials from the penitentiary, officials said.
Wu Lei, director of Shandong's prison administration, said the new cases showed that "the implementation of our prevention and control measures has not been effective".
Another 34 cases were found at Shilifeng prison in eastern Zhejiang province, leading to the ouster of its director and another official.
Hubei announced earlier on Friday that a total of 411 new cases of the virus were confirmed in the province on Thursday, but later revised its figure up to 631 to include the prison numbers.
The clusters came as Chinese authorities have pointed to a drop in officially reported new cases this week as evidence that quarantines and other drastic measures to contain the virus are working.
Most of China remains paralysed over fears of contagion, with schools remaining closed and Beijing ordering those returning to the city to self-quarantine for 14 days.
New cases at two hospitals in the country's capital have also emerged.
Health officials said 36 patients, medical workers and family members have been infected with the virus at Beijing's Fuxing hospital, which has been partially sealed off since January 31.
An elderly woman receiving kidney treatment at Peking University People's Hospital also tested positive after two infected relatives visited her earlier this month, the hospital said.
People who came into close contact with those infected at both hospitals are being monitored, while 12 women and 10 infants from the obstetrics ward have been ordered to leave Peking University People's Hospital for their own safety, authorities said.
Members of China's Uighur minority living in exile have also warned of the risk of the coronavirus spreading in internment camps, where rights groups say more than one million people have been rounded up by authorities.
The virus spreads through droplets disseminated by sneezing or coughing, highlighting the risks for large groups of confined people, possibly without adequate access to soap and water.
