Renowned virologist China Shi Zhengli, director of the Wuhan Laboratory, which identified the cause of the infection in the United States, said this week that people need to be vaccinated as the virus continues to change and that the world must be prepared to live with it.
“As the number of infected cases has increased, it is more likely that the new corona virus will be replaced and selected. New strains will continue to emerge.”According to the South Morning China Post (SCMP), Xi told a local Chinese store.
In that sense, the scientific community needs to develop and improve new vaccines to “prevent upper respiratory tract infections against the virus,” Shi said.
Xi, director of the Wuhan Institute of Virology’s Center for Emerging Infectious Diseases, has been pointed out by politicians and scientists in the United States that he was responsible for the origin of the cov-19 from his study of bats and their origin. Different corona virus. Her team, nicknamed the “Bad Woman”, denies the virus escaped from a laboratory in the Chinese city where the origin of the infection was identified.
Shi published an article last year claiming that Chinese horsetail bats are the natural host of the corona virus, and that bats are a natural reservoir of corona virus.
A close relative of Sars-CoV-2 is a corona virus that was first identified in 2013 by Shi and his team in a cave in the southwestern province of Yunnan. But the genetic sequence of bats of that type shows only 96 percent similarity, viruses differ for decades in evolution, as some theories pointing out against Shik indicate, destroying the formation of the virus in a laboratory.
Already in 2020, the virologist said, new strains will be common because the virus is mutable. Today, the world is facing delta variation and is spreading rapidly so far, with at least 135 countries reporting cases of this mutation, according to the World Health Organization.
New generation vaccines
Xi not only said that the world should no longer live with the corona, according to SCMP, Jin Dongyan, a professor of molecular virology at the University of Hong Kong, agreed with the virologist and said that people should live together. The virus “lasts a long time or forever.”
Jin, like Shia, works on a new generation of vaccines, explaining that thanks to them, despite the mutations, SARS-Cowie-2 could eventually be wiped out like the plague or polio as vaccines are improved.
“There is no limit to the potential for the virus to change,” Gin explained, adding that the mutation rate of SARS-COV-2 is lower than that of influenza and HIV-1.
“Current vaccines are injected into our muscles and protect our lungs, but they do not neutralize infection in our upper respiratory system,” he explained.
