China to scrap PCR test requirement for inbound travellers

Travellers entering China will no longer need to provide a negative PCR test result starting from Saturday, in another easing of China's 'zero-COVID' policies.

Travellers can instead show a negative antigen test result taken within 48 hours before boarding, Chinese Foreign Ministry spokesperson Mao Ning told reporters Tuesday.

Over the last three years, China imposed an array of anti-virus controls to try to eliminate the virus from the community, including lockdowns and regular mass testing. But after the rules hammered the economy and sparked protests, the government suddenly rolled back its onerous measures in December and made a major step to drop its quarantine rule in early January.

Last month, the country resumed the issuance of all types of visas as part of its efforts to revive tourism. Still, it has kept PCR testing requirements for passengers arriving from some countries - a costly requirement that was a major deterrent for visitors to return.

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.
