China's Communist Party claims 'decisive victory' over COVID

Since December last year, millions of people in China contracted the Omicron virus and unofficial reports said thousands of people, especially those above 60 years old, fell victim to it.

China's ruling Communist Party has claimed to have scored a 'decisive victory' over the coronavirus pandemic by minimising the casualties and staunchly defended its much-criticised zero-COVID policy, saying that it has succeeded in preventing the widespread prevalence of variants.

Since December last year, millions of people in China contracted the Omicron virus and unofficial reports said thousands of people, especially those above 60 years old, fell victim to it.

More than 200 million people were treated and nearly 800,000 patients in severe conditions received effective treatment, according to an official press release issued after the party's political bureau meeting held on Thursday.

With a strong sense of responsibility and strategic resolve, China has optimised and adjusted the COVID-19 prevention and control measures in light of the evolving situation, and effectively balanced pandemic containment with economic and social development, it said.

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.
