Scientists have the same procedure that allowed Severe Acute Respiratory Syndrome (SARS) to infect people, but the mutation discovered derails them.
Scientists say the substitution occurred in a component of the complex protein that the new coronavirus binds to certain human cells. The design targets cells containing ACE2, an enzyme discovered in cells on the outer surface of the lungs, which allowed the SARS virus to infect people, the South China Morning Post first reported.

Researchers know a lot about the receptor and have analyzed the antibodies to attack it, but the structural mutation may have put all studies at risk.
Collaborators at Murdoch University in Australia, as well as wei-Lung study authors from Changhua National University of Education in Taiwan, said the strain in India is the first report of a significant mutation in the series.
“The result of this study sounded the alarm that a Sars-CoV-2 mutation that varies depending on the epitope profile (to which an antibody attaches) can occur at any time. This means that the existing progression of a Sars-CoV vaccine -2 is at increased risk of becoming useless.”

His study, which has not been peer-reviewed, was first published on the pre-printing review site biorvix.org this weekend.
While the Indian strain, taken from a patient in Kerala, was presented to the National Institute of Virology in early January, the entire genome series was published two months later, a long delay that baffles some researchers.

According to the SCMP, “there is a growing fear that thousands of sampled and sequenced strains will be just the tip of the iceberg, and a wide variety increases the threat that new strains will require new vaccines just like the influenza virus.”
Despite the reverse, scientists around the world rushed to locate a vaccine opposite a virus that inflamed 1.9 million people worldwide on Tuesday morning and has a death toll of 120450, according to knowledge provided through Johns Hopkins University. In the United States, there were 582,590 cases and 23,649 deaths.
