Explainer: What we know about China-made vaccines – World news

China was ahead in the global race to develop coronovirus vaccines with the most candidates in the late phase of testing at the beginning of the year and on Thursday got the first approval of a homemade shot for the general public, yet no detailed influential data did not get.

We are aware of China’s vaccine development, efficacy data and approval times.

Which are the most advanced?

Five vaccines from Synovac Biotech, China National Pharmaceutical Group (Sinopharma), Cancinobio and the Chinese Academy of Sciences are under late clinical trials. Neither of them has released detailed efficacy data.

Officials on Thursday approved a vaccine developed by Sinopharm’s Beijing affiliate, a day after the developer said an interim analysis of its Phase 3 trial showed 79.34% efficacy without providing details.

The efficacy readings for the same vaccine are less than 86% based on the initial vaccine announced by the United Arab Emirates on 9 December.

A Sinopharma executive said detailed data would be released on Thursday without giving a detailed timeline.

Synovac candidate has also read various efficacy. Data from a late-stage trial of its Coronavac shot in Turkey showed a 91.25% success rate, while researchers in Brazil stated that its efficacy ranged between 50% and 90%.

Brazil expects Coronavac’s efficacy data to be released by 7 January after three delays.

A top Mexican health official said that Cansoinobi plans to submit clinical trial results for its vaccine to authorities in Mexico next week.

How many people have been deactivated?

While China has been slower than many other countries in approving Kovid-19 vaccines, it is vaccinating its citizens with three different shots undergoing late-stage tests.

China launched an emergency use program aimed at high risk of infection to essential workers and others in July and has administered two doses of cyanopharma and more than 4.5 million doses of Synovac’s Coronavac.

This has been intensifying the program over the past month in anticipation of greater transmission risks during winter.

The South China Morning Post newspaper reported that China would vaccinate 50 million people before the Lunar New Year holiday in mid-February.

China has also approved a vaccine for cannabino for military use and the vaccine has been given to some 40,000 to 50,000 people, a CancinoBio executive said on 28 November.

Which technique is used?

Sinopharma and Synovac vaccines are based on traditional techniques that use inactivated or dead viruses, which cannot replicate in human cells to trigger immune cells.

National Health Administration official Zeng Rixin said Thursday, the overall incidence rate of adverse reactions to those Kovid-19 shots is similar to other inactivated vaccines, and the allergic rate of relatively severe adverse effects is also nearly two million. .

Who is buying China’s vaccines?

The United Arab Emirates became the first country to administer a Chinese vaccine to the public this month.

Pakistan on Thursday announced a 1.2 million dose purchase deal with Sinopharma.

Synovac’s Coronavac shot has been signed by Brazil, Indonesia, Turkey, Chile and Singapore. The company is also in supply talks with Malaysia and the Philippines.

CanSinoBIO is a supply deal with Mexico.

President Xi Jinping has pledged to make China’s vaccines good for the global public.
