Thousands of runners took to the streets of China's capital on Sunday for the return of the Beijing marathon after a two-year COVID-19 hiatus, even as another death blamed on China's strict pandemic controls generated more public anger.

Authorities are trying to restore a sense of normalcy while sticking to a zero-COVID strategy that locks down neighborhoods when any virus cases are found and quarantines everyone arriving from overseas in hotels for seven to 10 days.

A simmering public frustration, which has grown as the rest of the world opens up, has been fueled by a series of tragic incidents — in several cases because people were denied timely care for non-COVID-19 medical emergencies.

An investigation report released Sunday by authorities in Hohhot, the capital of China's Inner Mongolia region, blamed property management and community staff for not acting quickly enough to prevent the death of a 55-year-old woman in a sealed building after being told she had suicidal tendencies.

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.
