The local government in Chengdu, southwestern China, confirmed, on Saturday, that the authorities have agreed to conduct human tests for a possible vaccine for the emerging corona virus, grown inside insect cells.

China is in a global race to develop effective and inexpensive vaccines to curb the COVID-19 pandemic.

The city government said, in a notification on social media, that using insect cells to grow proteins in order to obtain a vaccine for the Corona virus, the first of its kind in China, could accelerate large-scale production.

According to the notice, the vaccine, developed by the “West China” Hospital of Sichuan University in Chengdu, has obtained approval from the National Administration of Medicinal Products to enter a clinical trial.

He added that, when testing the vaccine in monkeys, it was shown to prevent SARS-Cove-2 infection without apparent side effects.

Chinese scientists are already leading work on at least eight other potential coronavirus vaccines that have entered various stages of clinical trials.

Foreign parties, including “Bio-Tech” Germany and “Innovio Pharma” in the United States, have cooperated with local companies to test their experimental vaccines in China.

The race to develop an effective vaccine has become intense in different countries around the world, and some have reached advanced stages of testing.

At the end of last July, the World Health Organization counted 26 candidate vaccines, which are being evaluated through human clinical trials.

Most of these trials are still in the “first stage”, which is mainly aimed at assessing the safety of the product, or the “second stage” when the issue of effectiveness is actually explored.

There are at least five vaccines in the most advanced “third stage”, as the effectiveness is measured on thousands of volunteers, and this applies to the experimental vaccines developed by the German companies “Biontech” and “Pfizer” of the United States, and the American “Moderna” laboratories and the laboratories of “Sinopharma” and “Senovac” China and the University of Oxford, in cooperation with the British “AstraZeneca”.
