- Three county-level health officials in Jiangsu province have been dismissed since the case came to light earlier this week.
- Beijing announced a nationwide clean-up of the country's vaccine industry last year after it emerged that a major Chinese manufacturer of rabies vaccines had fabricated records.
At least 145 children were administered expired polio vaccines in eastern China, state media reported, despite the government promising to prevent such lapses in the industry following a major scandal last year.
Three county-level health officials in Jiangsu province have been dismissed since the case came to light earlier this week -- the latest to raise public health concerns -- according to an announcement by the Jinhu county government.
A parent discovered earlier this week that a batch of orally administered polio vaccines were being given to children at a county-run health facility nearly one month after their December 11 expiration date, state broadcaster CCTV reported on Thursday.
The local government has since found 145 children received the vaccines between December 11 and January 7, CCTV said, quoting a government source.
Local health officials have said the expired vaccines would have decreased efficacy but should not cause adverse health effects.
The World Health Organisation's website says that people given such vaccines that have expired are "unlikely to get sick as a reaction to receiving the vaccine" but warns that they might not be adequately immunised.
