China approves first nasal spray COVID-19 vaccine for trials
Beijing: China has approved for trials its first nasal spray vaccine to combat the novel coronavirus that has claimed over 904,000 lives and infected more than 27 million people globally, official media here reported on Thursday.
China's only nasal spray vaccine against the coronavirus is expected to start phase I clinical trials in November, and it is recruiting 100 volunteers.
It is the only vaccine of its type approved by China's National Medical Products Administration, the state-run Global Times reported.
The vaccine is a collaborative mission between Hong Kong and the Chinese mainland that involves researchers from the University of Hong Kong, Xiamen University, and Beijing Wantai Biological Pharmacy.
Microbiologists from the University of Hong Kong, Yuen Kwok-Yung, said the vaccine stimulates the natural infection pathway of respiratory viruses to activate the immune response.
The nasal spray vaccination could generate double protection for vaccine recipients - influenza and the novel coronavirus if it also contains influenza viruses including H1N1, H3N2 and B, Yuen said, adding that it would take at least another year to finish the three clinical trials.
A Beijing-based immunologist told the daily that compared with injections, a nasal spray vaccination is easier to administer and would also be easy to mass-produce and distribute as it adopts the mature influenza vaccine production technology.
The nasal spray vaccine uses live attenuated influenza vaccine; the other four technical routes China is using to develop the coronavirus vaccines are inactivated vaccines, adenoviral vector-based vaccines, and DNA and mRNA vaccines. The inactivated vaccine is estimated to be the earliest to be in the market, the report said.
The immunologist said the new vaccine may not cause systemic side effects, but side effects may occur in the respiratory system such as asthma and shortness of breath.
Ideally, scientists do not expect side effects except for minor nasal obstruction or rhinorrhea, Yuen said.
It is not yet clear whether immunity generated from nasal spray vaccinations will last longer than for injected vaccines, the report said.
China has approved three COVID-19 vaccine candidates for clinical trials. It has also authorised emergency usage of COVID-19 vaccines developed by some select domestic companies.
"We've drawn up a series of plan packages, including medical consent forms, side-effects monitoring plans, rescuing plans, compensation plans, to make sure the emergency use is well regulated and monitored," Zheng Zhongwei, head of China's coronavirus vaccine development task force told the official media here last month.
An emergency use authorisation, which is based on Chinese vaccine management law, allows unapproved vaccine candidates to be used among people who are at high risk of getting infected in a limited period.
The Global Times has previously reported that employees of state-owned enterprises (SOEs) preparing to go abroad and the frontline medics have been offered two choices of domestic inactivated vaccine candidates developed by Sinopharm for urgent use.
The novel coronavirus, which originated from China's Wuhan city in December last year, has claimed 904,485 lives and infected 27,902,002 globally. The US is the worst affected country with 190,887 deaths and 6,363,729 infections, according to the Johns Hopkins University data.

Odisha Police arrests key accused in Rs 40-crore investment fraud
Bhubaneswar (PTI): Odisha Police's Economic Offences Wing (EOW) has arrested the prime accused in a Rs 40-crore trading fraud, an officer said on Friday.
The accused, identified as Amit Mandal of West Bengal's Bankura, was arrested from his home district on December 31, the officer said.

After producing him in a local court there, Mandal was brought to Odisha on Friday, the EOW officer said.
The arrest was made in connection with a case registered on December 29 at the EOW police station on the basis of a complaint lodged by Sushant Kumar Das of Khurda district.
The complainant alleged that Mandal and his associates induced him to invest in share trading by promising high monthly returns ranging from 3.5 to 7 per cent per month.
Das had reportedly deposited Rs 8.5 lakh during 2022–2024.
According to police, Mandal induced around 500 depositors from Odisha and 100 from West Bengal between 2020 and 2024 and collected over Rs 120 crore, of which over Rs 40 crore is yet to be returned to investors.
"Initially, he paid monthly returns of depositors. However during 2023, Mandal failed to pay the returns and falsely assured the depositors that their money will be re-invested in his newly formed company. But suddenly he went missing before being arrested in Bankura district," the official said.
According to the EOW, the accused had been collecting deposits in his personal bank accounts maintained with two banks. "Scrutiny of one bank account revealed transactions amounting to Rs 122 crore. Other accounts are under verification," the officer said.
