China on Monday questioned US Secretary of State Antony Blinken's charge that Beijing has helped the WHO scientists to write the soon-to-be-released report on the origins of the coronavirus, saying that Washington is making such allegations to put pressure on the experts team.

Blinken in an interview to CNN on Sunday expressed concern about the "methodology and the process" followed by the forthcoming WHO report on the origin of the coronavirus. There is a report coming out shortly by the World Health Organisation. There are real concerns about methodology and the process that went into that report including that fact that the government in Beijing has helped to write it. But let us see what comes out of that report, Blinken said.

He said there needs to be "accountability for the past" and "focus needs to be on building a stronger system for the future." "I think the issue for us is to make sure that we do everything possible to prevent another pandemic even as we're working through this one or at the very least to make sure that we can mitigate in much more effective ways any damage done if something happens in the future," he 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.
