According to a report published in People’s Daily, vaccine maker CanSino Biologics Inc has won a patent approval from Beijing for its COVID-19 vaccine candidate Ad5-nCOV.
According to the report, which is based on the documents from the country’s intellectual property regulator, the patent was submitted for application on March 18, and was approved on August 11.
China’s CanSino’s vaccine uses a modified common cold virus to carry genetic material from the new coronavirus into the human body, a method also used by the Oxford/AstraZeneca vaccine.
Both vaccines elicited antibody and T-cell immune responses and neither prompted any serious side effects in early trials. T-cells are an important component of the immune system’s attack against foreign invaders, such as viruses.
Results of both trials were released in the medical journal the Lancet.
Other potential vaccines developed jointly by Sinovac Biotech and a unit of China National Pharmaceutical Group (Sinopharm) have also moved to Phase III trials.
All five types of COVID-19 vaccines in China are being developed under international cooperation with a list of countries including the UAE, Brazil, the UK, the US and Germany, media reported.
