A vaccine against tooth decay “is urgently needed” writes Nature — and a team of Chinese scientists is getting close. hackingbear writes: Scientists at Wuhan Institute of Virology, Chinese Academy of Sciences developed low side effects and high protective efficiency using flagellin-rPAc fusion protein KFD2-rPAc, a promising vaccine candidate. In rat challenge models, KFD2-rPAc induces a robust rPAc-specific IgA response, and confers efficient prophylactic and therapeutic efficiency as does KF-rPAc, while the flagellin-specific inflammatory antibody responses are highly reduced.
