China's drug administration has suspended the use of two batches of hepatitis B vaccines after two dead cases occurred after vaccination.

The China Food and Drug Administration on Saturday published a circular urging relevant local authorities and disease control centers to suspend two batches of the vaccines produced by a Shenzhen-based company.

Two people in central China's Hunan Province died after receiving hepatitis B vaccinations from the company, and the suspicious two batches were found to have been sold to Hunan, Guangdong and Guizhou provinces.

The authority has informed relevant agencies in the three provinces and local drug administration in Shenzhen has been told to send a team to the company for investigation.
