China is the latest country mixing things up when it comes to COVID-19 boosters. Since boosters were implemented in China in October, adults have been given a third dose of their primary vaccine regimen, which has consisted of one of three inactivated vaccines produced by Sinopharm Group Co. Ltd. and Sinovac Biotech Ltd.
In addition to the four COVID-19 vaccines it has provisionally approved, Australia’s Therapeutic Goods Administration (TGA) is recommending that two more vaccines – Sinovac Biotech Ltd.’s Coronavac and Astrazeneca plc-Serum Institute of India’s Covishield – be considered “recognized vaccines.”

Chinese companies are finding that their COVID-19 vaccines are effective as booster shots and against variants of the virus, as data from more studies emerge. Those who have received the third dose of Sinovac Biotech Ltd.’s COVID-19 vaccine, Coronavac, showed 2.5-fold higher neutralizing potency against the Delta variant, compared to COVID-19 convalescents and two-dose vaccinees.

Sinovac Biotech Ltd. said booster shots of its Coronavac vaccine against SARS-CoV-2 induce strong immune responses in adult and elderly populations following a considerable loss of antibodies six to eight months after completing the current two-dose regimen.
The lack of data surrounding the efficacy of Chinese COVID-19 vaccines against the Delta variant has had many questioning them, especially after a recent study showed that one of those vaccines, Sinovac Biotech Ltd.’s Coronavac, was less effective than Pfizer Inc. and Biontech SE’s Comirnaty in Chile.

Sinovac Biotech Ltd.'s inactivated COVID-19 vaccine, Coronavac, has been approved by Chinese regulators for emergency use in children aged between 3 and 17, the company’s CEO Yin Weidong told Chinese state media on June 4. Sinovac briefly unveiled phase I/II data in the age group back in April. Chinese state media, China Central Television, said it confirmed the news with an expert from China’s State Council, though an official announcement has yet to be made. Sinovac did not immediately respond to BioWorld’s query to confirm the news.
