An inspection team was dispatched to check the disposition of substandard DPT vaccines produced by Wuhan Institute of Biological Products Co., Ltd. Wednesday.

The team is jointly formed by members from departments including the State Drug Administration (SDA) and National Health Commission, and led by Li Li, deputy director of the SDA.

DPT refers to a combination of vaccines for three infectious diseases: diphtheria, pertussis, and tetanus.

A batch of 400,520 doses of DPT vaccines produced by Wuhan Institute of Biological Products Co, Ltd. was found defective due to a short-term failure in the packaging equipment last year. The finding was disclosed to the public in November 2017.

The biological company was fined, and its illegal gains were confiscated.
