Vaccination Efforts

Vaccination efforts are underway targeting at-risk groups by County public health and our community health care partners. Because of the outbreak, the hepatitis A vaccine has now been recommended for people who are homeless, illicit drug users, staff at homeless service providers and substance use treatment agencies, public safety and emergency workers, health care workers and sanitation workers.

Hygiene Kits

As part of its hepatitis A infection prevention efforts, the County of San Diego Health and Human Services Agency has hygiene kits available to help promote handwashing (pictured right). These kits contain hand sanitizer (as available), cleansing wipes, bottled water, an informational flyer, and a waste bag. The kits are being provided to community partners that serve homeless persons and illicit drug users who are at risk for hepatitis A infection and who have limited access to handwashing facilities. When distributing kits to clients, community partners are encouraged to also recommend the hepatitis A vaccination.
