Despite the fact that many existing viruses not yet defeated finally, there are all the same and the ones that humanity has managed to cope. One of these is the smallpox virus, but a group of researchers from the University of Alberta recently recreated a deadly virus. According to the publication Sciencealert, it will help in the course of further investigation and fight against other serious pathogens. However, not all the scientific community shares this view, and some see this as a huge biological threat.
It is worth mentioning that the who (world health organization) declared victory over smallpox in 1979 through a global vaccination of the population. In those same years, it was decided to destroy all available laboratory samples of the virus. However, according to the publication, two canadian biologists David Evans and Ryan Noyce in the laboratory created samples of the smallpox virus by manipulation of viral RNA using chemically synthesized DNA. Scientists then warned that we are talking about a horse pox, however, further research has shown that under certain conditions the virus can be dangerous to humans.
Many scientists believe that the re-creation of a dangerous virus can lead to the emergence of new biological weapons, and even the emergence of a pandemic. But, as stated by the authors, their findings indicate that editing methods and application of synthetic DNA can be used in the pharmaceutical industry to create drugs of new type, particularly the so-called virus-killers, who will be able to destroy pathogenic cells and bacteria without affecting the healthy tissue.
