TB Booster

1533546915216148.pngTB Booster is a recombinant human type 5 adenovirus-based 

tuberculosis vaccine, a globally innovative TB booster vaccine

 for BCG-vaccinated population. Currently, BCG is the only available

 TB vaccine in world and all newborns in the PRC are required to

 receive the BCG vaccination. However, the efficacy of BCG declines

 after 10 to 20 years from primary vaccination and no effective BCG booster vaccine is available. Our TB Booster candidate would be indicated for the 4 to 18 year-old age group in China, which had a total population of 290.0 million in 2017. The phase I clinical trials of our TB Booster candidate are expected to be completed in Canada by the end of 2019.
