China National Biotec Group Co. (CNBG), a leading vaccine developer has sought authorisation to bring its COVID-19 candidate to the market, Bloomberg has reported.

The Bloomberg report cites Shi Shengyi, the vice general manager of Sinopharm – CNBG’s parent company – as saying that an application in this regard was submitted to Chinese regulators on November 25. The application is likely to include data from the phase-3 clinical trials that were conducted in the Middle East and South America.

CNBG, Sinopharm Group and China’s drug regulator, the National Medical Products Administration, did not immediately confirm this development.

This would make CNBG the first drugmaker outside Russia to seek general use authorisation for its vaccine candidate against COVID-19, the disease caused by the novel coronavirus.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

The move is being seen as an attempt to challenge rivals from the United States and the United Kingdom as the race to develop a vaccine against COVID-19 heats up. Western vaccine developers such as Pfizer, Moderna and AstraZeneca are yet to formally seek emergency use authorisation from regulators.

CNBG had said its phase-3 human trials involved more than 50,000 people in countries such as Argentina to Egypt and had progressed smoothly. It had also said there had been no serious adverse events. However, unlike its Western rivals, CNBG is yet to release phase-3 efficacy data of its vaccine candidate. Thus, it remains unclear how quickly will the shot be approved by the Chinese regulators.

The news report suggests CNBG has signed supply agreements with multiple countries including Malaysia, Brazil, Pakistan and the United Arab Emirates (UAE).

Moneycontrol’s full coverage of the coronavirus pandemic

More than 5.9 crore people have been infected by the disease so far leading to over 14 lakh deaths. While the number of new COVID-19 cases being reported has fallen in some countries, others fear a second wave of infections. Rapid and effect inoculation is being seen as the only way to end the pandemic.

Yet, despite vaccines having not been approved, they are already in widespread use. Hundreds of thousands of people in China are believed to have been inoculated under an emergency-use program, leading to concerns in the scientific community.
