Researchers from the Wuhan Institute of Virology at the Chinese Academy of Sciences recently published a study in the journal Scientific Reports about the vaccine they are working on which would help you keep your teeth healthy (although you’ll still need to brush and see the dentist for cleanings).
According to the WHO dental carries are a huge health problem in most industrialized nations (let alone developing nations) so there is serious money to be made with a vaccine like this. (Opps, sorry, I meant there are people to help. I hope you get the sarcasm.)
“Led by WIOV scientist Yan Huimin, the researchers tested a fusion of proteins to prevent the development of dental caries. Better known as dental cavities, caries is caused by the bacteria Streptococcus mutans (S. mutans).”
The current fusion of proteins they have found to work were used on mice and rats via their nasal cavity. Overall, it was shown to offer a high level of protection against dental caries.
Much more testing will need to be done before the vaccine is ready for clinical tests.
