Beijing to reopen schools, Shanghai declares victory over COVID

The two major cities were among several places in China that implemented curbs to stop the spread of the Omicron wave during March to May, with Shanghai imposing a two month-long city-wide lockdown that lifted on June 1.

Beijing on Saturday said it would allow primary and secondary schools to resume in-person classes and Shanghai’s top party boss declared victory over COVID-19 after the city reported zero new local cases for the first time in two months.

The efforts, part of China’s adherence to a zero-COVID policy that aims to eradicate all outbreaks, have brought case numbers down but many of the heavy-handed measures have fuelled anger and even rare protests and taken a heavy toll on the economy.

Beijing shut its schools in early May and asked students to move to online learning amid a spike in locally transmitted COVID cases. Senior year students at middle and high schools were allowed to return to classrooms from June 2.

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.
