Britain develops anti-cavity vaccine by changing tobacco genes
Scientists at the Gass Hospital in London used genetic engineering methods to extract vaccines by changing tobacco genes. Genetically modified tobacco produces an antibody that kills the bacteria that rotted the tooth. When the scientists extract this antibody from tobacco and put it into a solution, the solution can be used to protect it by coating the solution on the teeth. The trial conducted by Gass Hospital showed that this vaccine can prevent the recurrence of bacteria that cause tooth decay within 4 months. Although some Other bacteria have been replaced in the mouth, scientists believe that those bacteria appear to be harmless. There are usually thousands of different bacteria in a person's mouth. In fact, only a few bacteria have the ability to rot teeth.
