Can anyone find any information to show that anything has changed since this statement?
In the United States, The National Childhood Vaccine Injury Act of 1986 established a Committee from the Institute of Medicine (IOM) to review the adverse consequences of childhood vaccines.
This group found severe limits in the knowledge and research capability on vaccine safety.
Of the 76 vaccine adverse events they reviewed for causal relation, 50 (66%) had no or inadequate research.
Specifically, the IOM Committees identified the following limitation's:
1) Inadequate understanding of biologic mechanisms underlying adverse events;
2) Insufficient or inconsistent information from case reports and case series;
3) Inadequate size or length of follow-up of many population-based epidemiologic studies;
4) Limitations of existing surveillance systems to provide persuasive evidence of causation and
5) Few experimental studies published relative to the total number of epidemiologic studies published.13,14
