The swelling protests against severe COVID-19 pandemic restrictions in China — the world’s second-largest economy — are injecting a new element of uncertainty and instability into the global economy when nations are already struggling to manage the fallout from a war in Ukraine, an energy crisis and painful inflation.

For years, China has served as the world’s factory and a vital engine of global growth, and turmoil there cannot help but ripple elsewhere. Analysts warn that more unrest could further slow the production and distribution of integrated circuits, machine parts, household appliances and more. It may also encourage companies in the United States and Europe to disengage from China and more quickly diversify their supply chains.

Millions of China’s citizens have chafed under a tight lockdown for months as the Communist Party seeks to overcome the spread of the COVID-19 virus, three years after its emergence. Anger turned to widespread protest after an apartment fire last week killed 10 people and comments on social media questioned whether the lockdown had prevented their escape.

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.
