The Centers for Disease Control (CDC) estimated that 732,000 American children were saved from death and 322 million cases of childhood illnesses were prevented between 1994 and 2014 due to vaccination.
About 30,000 cases of adverse reactions to vaccines have been reported annually to the Vaccine Adverse Event Reporting System (VAERS) since 1990, with 10-15% classified as serious, meaning associated with permanent disability, hospitalization, life-threatening illness, or death.
