‘Zero COVID,’ once ubiquitous, vanishes in China’s messy pivot

While the rest of the world concluded months ago that the coronavirus was becoming less deadly, Beijing presented the development as fresh news to explain its abrupt decision to undo the lockdowns that prompted widespread protests.

A day after China’s ruling Communist Party announced a broad rollback of the “zero COVID” restrictions that had smothered the economy and transformed life in the country, the propaganda apparatus on Thursday began the daunting task of promoting an audacious revision of history.

While the rest of the world concluded months ago that the coronavirus was becoming less deadly, Beijing presented the development as fresh news to explain its abrupt decision to undo the lockdowns that prompted widespread protests. In doing so, it also made a high-risk bet that vaccination rates in China are sufficient, or soon will be, to prevent a severe outbreak that overwhelms the nation’s hospitals.

“The pathogenicity of the omicron strain of the coronavirus now is significantly reduced,” Wang Guiqiang, a health expert, told reporters in Beijing at a news briefing on Thursday that was widely covered in state media. “Everyone should treat it with a normal heart — there is no need to be nervous or even fearful.”

State television also trumpeted assertions that more than 90% of cases of the year-old omicron variant are mild or asymptomatic, without explaining the sudden embrace of such conclusions. The health commission released details on how residents should quarantine at home if they test positive, instead of at hospitals. Workers began tearing down testing booths. Officials detailed new limits on when and how local authorities can impose lockdowns.

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.
