In August 2019, 30 attendees at a Nebraska wedding developed mumps after being exposed to one asymptomatic index patient who was fully vaccinated according to Advisory Committee on Immunization Practices (ACIP) recommendations (1), resulting in a multistate outbreak. A public health investigation and response revealed epidemiologic links that extended from the index patient through secondary, tertiary, and quaternary patients and culminated in a measles-mumps-rubella (MMR) booster vaccination campaign in the local community where approximately half of the patients resided.
2019 年 8 月，30 名参加内布拉斯加州婚礼的人在接触到一名无症状的指数患者后患上了腮腺炎，该指数患者根据免疫实践咨询委员会 (ACIP) 的建议（1）完全接种了疫苗，导致了一次多州暴发。公共卫生调查和应对揭示了从指数患者到二级、三级和四级患者的流行病学联系，最终导致在当地社区开展了麻疹-腮腺炎-风疹（MMR）加强疫苗接种运动，大约一半的患者居住在该社区。
