DTcP (Booster)


 DTcP Booster is a vaccine being developed by us that 

addresses the weaker protection preventing pertussis 

after primary vaccination, designed for children

(4 to 6 years old). We are developing a potential China

 first-in-class DTcP booster vaccine to address the lack

 of vaccines that protect against pertussis after  primaryvaccination of co-purified DTaP vaccines. Our DTcP booster candidate received CTA approval in 2018. We have commenced a phase I clinical trial, which we expect to complete in 2019.
