COVID-19 origin probe: US intelligence agencies access genetic data from Wuhan lab

Earlier, multiple experts and media reports have even warned that the novel coronavirus could have been leaked from China's Wuhan lab.

The US intelligence agencies have accessed massive genetic data from China's Wuhan lab and are scouring them to find the origin of the COVID-19 pandemic, reported CNN citing sources.

According to the report, the accessed data contains genetic blueprint information from virus samples studied at Wuhan lab, which several American officials still believe may have been the source of the COVID-19 outbreak, the media report said.

The novel coronavirus first emerged in China’s Wuhan in 2019.

The report further said it still remains unclear how or when the US intelligence agency gained access to the information. However, reportedly, the machines involved in the creation and processing of such genetic data from viruses are connected to external cloud-based servers leaving the possibility of being hacked.

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.
