A<unk>  (VAE), sometimes referred to as a vaccine injury, is an<unk><unk>  caused by vaccination. The World Health Organization (WHO) knows VAEs as<unk><unk> s Following Immunization (AEFI). AEFIs can be related to the vaccine itself (product or quality defect-related reactions), to the vaccination process (error or stress related reactions) or can occur independently from vaccination (coincidental) and are classified as: * Vaccine product-related reaction * Vaccine quality defect-related reaction * Immunization error-related reaction * Immunization anxiety-related reaction * Coincidental<unk>  Most<unk> s are mild. Serious injuries and deaths caused by vaccines are very rare, and the idea that severe<unk> s are common has been classed as a "common misconception about immunization" by the WHO. Some claimed vaccine injuries are not, in fact, caused by vaccines; for example, there is a subculture of advocates who attribute their children's autism to vaccine injury, despite the fact that vaccines do not cause autism. Claims of vaccine injuries appeared in litigation in the United States in the latter part of the 20th century. Some families have won substantial awards from sympathetic juries,<unk> though many public health officials have said that the claims of injuries are unfounded. In response, several vaccine makers stopped production, threatening public health, and laws were passed to shield makers from liabilities stemming from vaccine injury claims.
