TB vaccine development aimed at breaking transmission chain

Guangzhou Laboratory, a key State facility focused on studying respiratory diseases, is developing a vaccine that could completely break the transmission chain of tuberculosis in the coming years, Zhong Nanshan, a noted expert on respiratory illness, said in a video speech on Thursday.

Zhong made the remarks during a tuberculosis prevention and control awareness event in Guangzhou, Guangdong province, which served as a prelude to the 30th World TB Day on Monday.

"Ending the transmission of tuberculosis requires actions from the whole society, including early diagnosis and treatment, elimination of discrimination and technological breakthroughs," Zhong said.
