China outlines COVID-origin findings, ahead of WHO report

The briefing appeared to be an attempt by China to get out its view on the report, which has become enmeshed in a diplomatic spat. The U.S. and others have raised questions about Chinese influence and the independence of the findings, and China has accused critics of politicizing a scientific study.

Chinese officials briefed diplomats Friday on the ongoing research into the origin of COVID-19, ahead of the expected release of a long-awaited report from the World Health Organization.

The briefing appeared to be an attempt by China to get out its view on the report, which has become enmeshed in a diplomatic spat. The U.S. and others have raised questions about Chinese influence and the independence of the findings, and China has accused critics of politicizing a scientific study.

“Our purpose is to show our openness and transparency,” said Yang Tao, a Foreign Ministry official. “China fought the epidemic in a transparent manner and has nothing to hide.”

The report, which has been delayed repeatedly, is based on a visit earlier this year by a WHO team of international experts to Wuhan, the city in central China where infections from a new coronavirus were first reported in late 2019.

The experts worked with Chinese counterparts, and both sides have to agree on the final report. It’s unclear when it will come out.

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.

Feng Zijian, a Chinese team member and the deputy director of China’s Center for Disease Control and Prevention, said the experts examined four possible ways the virus got to Wuhan.

They are: a bat carrying the virus infected a human, a bat infected an intermediate mammal that spread it to a human, shipments of cold or frozen food, and a laboratory that researches viruses in Wuhan.

The experts voted on the hypotheses after in-depth discussion and concluded one of the two animal routes or the cold chain was most likely how it was transmitted. A lab leak was viewed as extremely unlikely, Feng said.

His remarks were reported by state broadcaster CCTV, which said envoys from 50 countries and the League of Arab States and the African Union attended the briefing at the Foreign Ministry.

“China firmly opposes certain countries’ attempts to politicize the origin tracing issue and make groundless accusations and hold China accountable,” the ministry said in an online post about the briefing.

Separately, Foreign Ministry spokesperson Hua Chunying said, “I would like to stress that virus tracing is a scientific issue that should be studied by scientists through cooperation.”

She told reporters that the experts are still discussing the contents and translation of the report, and she did not know when it would be released.
