title: Long-term analysis of sterility testing of immunobiological preparations.
abstract: The data for sterility testing for 16 years show a high stability from different points of view. The summarized and compared results after 10 and 16 years are similar, so we can assume a fixed methodological, technological and biological balance. The necessity of changes in these methods and the achieved balance is discussed.
