CCTV9英语新闻：禁止乙肝疫苗

And now let's take a look back at how this vaccination¹ crisis began.

On December 9th, three infants in central China’s Hunan province fell seriously ill after receiving hepatitis B vaccines³. Two of them later died. The vaccines came from the Shenzhen-based BioKangtai company, which produces more than half of all the hepatitis B vaccines in China.

Two days later, Hunan health authorities and police formed an expert investigation⁴ team to look into the matter.

On the 14th, the China Food and Drug Administration issued a notice urging disease control centers to suspend the use of two batches⁵ of BioKangtai’s vaccines. That night, Guangdong authorities moved to pull over 3,000 shots of the vaccine² from circulation.

This past Friday, Chinese authorities announced a ban on all hepatitis B vaccines produced by BioKangtai.
