According to Phillip Felgner and Huw Davies of the Department of Medicine at UC Irvine, a new artificially developed virus may be capable of replacing the current stockpile of smallpox vaccine.
Since an assortment of international scientists announced the eradication of smallpox in 1979 and the World Health Assembly formally endorsed this announcement in 1980, smallpox has long faded from the media’s eye in regards to potential global threats.
However, smallpox still exists in a contained state. In 2002, the World Health Organization changed its policy to focus on the final destruction of the disease. For this reason, different governments and international agencies have kept a standard smallpox vaccine in storage in case an accidental outbreak occurs.
The new cure developed and the vaccine virus infection works by creating a mild infection in humans that will subsequently make them immune to smallpox.
