The type of coronavirus detected in December 2019 whose source is not yet clearly known. SARS-COV-2, causing the disease COVID-19, which has killed millions of people to date. While there is no definitive finding on the source of the coronavirus species, the most widely accepted theory was that the virus came from bats.

While the virus has lost much of its lethality thanks to the COVID-19 vaccines, new news came out of Russia today. A newly published study shows that a new strain of the coronavirus has been detected in bats in Russia and that the virus can resist the antibodies in vaccines revealed.

It was originally discovered in 2020

The new virus, called Khosta-2, was discovered in horseshoe bats in Russia’s Sochi National Park, according to research published in the journal PLOS Pathogens. This bat species He also lived in Europe and North Africa. marked.

The virus strain was actually first discovered in 2020, along with the Khosta-1 virus. But the pathogens of the virus at that time was not seen as dangerous. Scientists have achieved remarkable results in their research in the laboratory environment.

In the tests performed, the angiotensin converting enzyme 2 (ACE2) receptors on human liver cells, tissue Infect in the same way as SARS-CoV-2 turned out to be able to use it. In addition, it was found that the receptor binding sites in the spike proteins also showed complete resistance to the monoclonal antibodies caused by the COVID-19 vaccine.

It is not known whether it can infect humans:

There has been no definitive finding on whether the new dangerous virus found in bats can be transmitted to humans. But when the virus is passed on to someone with a different strain of the coronavirus, risk of merging two viruses and creating a new variant was declared.

In the scientific world, no general protective vaccine against SARS-related coronavirus types has yet been developed. Developed vaccines generally replace these viruses. target specific viruses and provides protection against them. In particular, studies are underway to develop a vaccine that will cover all of these viruses.
