The Food and Drug Administration said in a statement on Sunday evening that its investigation had found that Changsheng fabricates production records and product inspection records, and arbitrarily changes process parameters and equipment, "serious violations" of the law. A number have now been recalled, but there is no information at this stage as to how they could affect the health of those children who have already been injected.
Authorities in Hebei announced yesterday that almost 150,000 people in the northern province received a sub-standard diphtheria, tetanus and pertussis vaccine made by another firm, Wuhan Institute of Biological Products.
Xi, who is now on a state visit to Rwanda, said people's health should always be a top priority and that their safety should be resolutely guarded, reports state-run news agency Xinhua. "We are anxious about the quality of domestic vaccines", said Yin, who said she had spent HK$5,000 ($640) on the inoculations: PCV13 which protects against pneumococcal bacteria, Japanese encephalitis and the ACWY vaccination to protect against meningitis.
Beijing's efforts to push domestically made vaccines have been hit by the latest crisis and faith in the state drug regulator to clean up the industry shaken.
First mentioned by Xi in November 2012, the Chinese dream shares many similarities with the American one, namely that every person will be able to get ahead and succeed, along with a recognition that China's economic growth in recent decades has not been equally distributed among the country's population.
Changsheng has been found to have faked production documents related to a rabies vaccine that is given to babies as young as three months, underscoring the difficulties China faces in cleaning up the image of what is the world's No.2 drug industry as it aims to promote locally made vaccines globally.
He called for authorities to "scrape the poison off the bone" in their efforts to rectify the vaccine problems.
Li's remarks were aimed at assuaging Chinese parents who complain about worrying over fake food, milk and medicine in a society that seems to lack a "moral bottom line" - and also competent, uncorrupt regulators.
"Those involved will be resolutely punished with zero tolerance".
"We will resolutely crack down on illegal and criminal acts that endanger the safety of peoples' lives, resolutely punish lawbreakers according to the law, and resolutely and severely criticize dereliction of duty in supervision", a statement on his website read.
The company is listed on the Shenzhen Stock Exchange.
For their mistake, Changsheng was fined 3,442,887 yuan ($507,843) by the Chinese government. Six of the children died.
While reactions to the Changsheng scandal were initially censored, it appears that Chinese censors have now been forced into being more lenient as the scandal has become the only piece of news that anyone in China seems to be talking about, with frequent updates and many threads on Weibo containing hundreds, if not thousands, of critical comments.
Relevant departments and local authorities should pay close attention and immediately probe the case to find the truth, Xi said, adding that the investigation should be thorough, the punishment severe, the accountability held seriously, and the case's progress should be publicized on time to address public concern.
