Researchers have presented the first vaccine against dental caries

As Med News notes, scientists of the Wuhan Institute of Virology have successfully tested a vaccine, which fights dangerous microflora and prevents dental caries. As previous studies have shown, Streptococcus mutans bacteria living in the oral cavity may cause caries.

These bacteria produce and release lactic acid into the environment. It provokes the formation of tartar, the enamel destruction and the appearance of carious cavities in the teeth. The vaccine is based on the fusion protein KF-rPAc.

KF protein, obtained from the different type of bacteria, elicits an immune response to the surface membrane protein rPAc of Streptococcus mutans. This allows to intensify the immunity attack against dangerous bacteria. As a result, the number of Streptococcus mutans in the oral cavity is reduced significantly.
