Wednesday December 31, 8:00 am ET
Mr. Xiaofeng Liang, director of National Planed Immunization Center of China CDC, stated, "All vaccines available on the Chinese market are considered safe products as they are produced and inspected through strict processes. It is impossible to cause disease by vaccinating with inactivated vaccines."
Mr. Weidong Yin, Chairman, President and CEO of Sinovac Biotech Ltd., commented, "Although the autopsy results showed that the death of the minor was not related to the administration of our vaccine, we are sorry for the family's loss. We are confident about the safety profile of Healive as supported by the clinical trials and the track record of vaccine administration following launch in 2002. Since vaccination has proven to be the most effective and successful approach to preventing diseases, we continue to supply our high quality vaccines in order to improve public health and maximize shareholder value."
As previously disclosed, the Health Services Bureau of Fengtai District in the City of Beijing suspended the use of 83 doses of inactivated hepatitis A vaccine Healive® following a report of the death of a minor in the Fengtai District on November 27, 2008, which coincided with the administration of the vaccine two days prior.
Classification of Adverse Events Following Immunization (AEFI)
According to WHO, five types of adverse events may occur following the administration of a preventative vaccine including: vaccine reaction, programme error, coincidental event, injection reaction and unknown. A coincidental event is the event that happens after immunization but is not caused by the vaccine.
