Batch release for biological products is an important mode of regulating vaccine safety and quality, as mentioned in article 74 of the Pharmaceutical Affair Act in Taiwan. This report outlines the statistical analysis of the batch release of common vaccines and toxoids from 2012 to 2014. Common vaccines consist of: Influenza vaccines, pneumococcal vaccines, diphtheria tetanus acellular pertussis vaccines, and rabies vaccines. Through analyzing and investigating these results, we expect that there will be a better understanding of the current situation of the batch release of frequently administrated vaccines and toxoids for the past three years, and that the results can be used as a resource to avert future epidemics.
