Treat liver cancer with smallpox vaccine

For the first time, an infectious disease has been removed, moreover, this vaccine can also help patients defeat liver cancer.

The vaccine for smallpox disease includes a live Vaccinia virus. The virus attacks cancer cells and neutralizes antiviral proteins and boosts molecules that attract the Vaccinia virus.

To improve the effectiveness of the Vaccinia virus, scientists have implanted a live virus into two variant genes. In it, a gene deprives the metabolism of enzymes in cancer cells to encourage it to replicate like other normal cells, the other gene produces proteins to absorb the immune system's attack.

Tests on 30 people with end-stage hepatocellular carcinoma showed that those who received high-dose vaccines had an additional life of up to 14 weeks, and those who used lower-dose antibiotics only lived for 7 weeks.

Currently, scientists are also testing this virus on colon cancer. Tony Reid - University of California (San Diego - USA), who presented the results of his research at the Liver Cancer Seminar last week in San Francisco.
