Researchers at Boston University added a spike protein from the Omicron variant with the original Wuhan strain, which has an 80% kill rate.
Researchers at Boston University say they have developed a new COVID strain that has an 80% kill rate following a series of similar experiments first thought to have started the global pandemic that began in China.
The variant, a combination of omicron and the original virus in Wuhan, killed 80% of the mice infected with it, the university said. When mice were only exposed to omicron, they experienced mild symptoms.
The research was conducted by a team of scientists from Florida and Boston at the school’s National Emerging Infectious Diseases Laboratories.
