42% of Adverse Reactions in Chinese Children are Caused by Vaccines

A male overrepresentation was observed regarding the total number of reports. The most frequently reported group of drugs were vaccines (42.15%). Skin rash and fever were the commonest symptoms reported in the total pediatric dataset. The proportion of children that suffered from a serious ADR was 2.16% and that for drug related deaths was 0.34%. And we found that the multiple drug exposure experienced a high proportion of serious ADRs compared with the single drug use (χ²=15.99, P<0.0001). Sixty-five percent of ADRs were for children less than 6 years of age. And more than half of reports were from doctors.
