Abstract
We investigated an outbreak of 5 hepatitis A cases among skilled nursing facility residents in Los Angeles County, California, USA, including 3 who were vaccinated after exposure. Our results suggest that persons in congregate living facilities should receive both the vaccine and immune globulin after hepatitis A exposure to mitigate further transmission.
