BEIJING: China’s health authorities said yesterday that they have found no link between a hepatitis B vaccine and the deaths of 17 children shortly after they were immunised.
An investigation into the deaths, reported between December 13 and 31, has found no evidence that they were caused by the vaccine, the China Food and Drug Administration and the National Health and Family Planning Commission said in a joint statement.
“Nine of the cases have so far been confirmed to have nothing to do with the vaccine,” said the statement.
But autopsies were still needed to confirm the cause of the other eight deaths, they said.
Reports of the deaths had sparked widespread public concerns after a series of food and health and safety scandals in recent years, largely due to lax and corrupt supervision and law enforcement.
An epidemiological analysis showed the 17 deaths were due to various “unidentical” problems, including severe pneumonia, kidney failure and suffocation, which were similar to the causes of deaths of children under five monitored by a national reporting network, they said in the statement.
Authorities have halted the use of BioKangtai’s hepatitis B vaccines while they investigate the issue. Previous reports in the Chinese media said more than 44 million doses of the drug were in stock or had been sold to 27 provinces and regions across the country.
Output at BioKangtai and two other Chinese vaccine manufacturers has been suspended since Wednesday because they failed to pass certification standards by a deadline of December 31.
Vaccination against hepatitis B is one of around 10 free but compulsory inoculations for most children in China. The vaccine is injected within 24 hours of birth, with further doses at one and six months. Afp
