Four infants in Hunan, Guangdong and Sichuan provinces recently died after being injected with hepatitis B vaccines produced by the Shenzhen-based BioKangtai, according to reports on cnr.cn.
While the cause of death is still under investigation, a two-month study
into the incidents is required to conclude whether the vaccines had in fact caused the deaths, according to Gao Lidong, deputy head of the Hunan Provincial Center for Disease Control and Prevention.
Chinese authorities suspended the use of the recombinant hepatitis B vaccines produced by BioKangtai on December 20.
Founded in 1988, BioKangtai is the largest manufacturer of hepatitis B vaccines in China, according to its website.

Stages of vaccination
Vaccination has been a key part of a successful national strategy to combat viral hepatitis in China, with the practice encouraged by the World Health Organization.
The vaccination for newborns is taken in three stages. The first shot must be taken immediately after birth. The second and third shots of the vaccine are taken after a baby is one month and then six months old, respectively.
Vaccination not for all
The hepatitis B vaccine is not suitable for all newborns. Those suffering from fever, weak immune system, low birth weight or serious eczema should not be given the vaccination.
Ensuring quality control
Hepatitis B vaccines are provided by the government free of charge. Health authorities are in charge of overseeing its purchase and production, while disease control centers are responsible for transporting refrigerated vaccines to hospitals. China has already established a system to monitor adverse reactions after vaccinations.
Degree of safety
The hepatitis B vaccine is one of the most developed and safe vaccines in the world. The vaccination is effective and inexpensive. Over 100 million new-born babies have received the vaccination since 1983 in China. The number of documented adverse reactions is within the acceptable limits, according to a spokesman for the Guangzhou Center for Disease Control and Prevention.
