TL;DR: This report summarizes the adverse events reported to the Vaccine Adverse Event Reporting System (VAERS) from January 1, 1991, through December 31, 2001, and indicates that the most commonly reported adverse event was fever, which appeared in 25.8% of all reports.

TL;DR: Although the role of varicella vaccine remained unproven in most serious adverse event reports, there were a few positive rechallenge reports and consistency of many cases with syndromes recognized as complications of naturalvaricella.

TL;DR: The Vaccine Adverse Event Reporting System (VAERS), the spontaneous reporting system for vaccine-associated adverse events in the United States, is evaluated as a public health surveillance system using evaluation guidelines from the Centers for Disease Control and Prevention.

TL;DR: Rigorous smallpox vaccine safety screening, educational programs, and older vaccinees may have contributed to low rates of preventable life-threatening adverse reactions.

TL;DR: It is found that the rate of reported adverse events among elderly vaccinees was higher than among vaccinees 25 to 44 years of age, and two additional deaths among elderly YF vaccinees are found, suggesting enhanced surveillance is needed.
