Why is this not a health priority? Especially vaccinating health workers, food workers and other who might come in contact with vulnerable populations?
Since March 2017, CDC’s Division of Viral Hepatitis (DVH) has been assisting multiple state and local health departments with hepatitis A outbreaks, spread through person-to-person contact.
The hepatitis A vaccine is the best way to prevent HAV infection
- The following groups are at highest risk for acquiring HAV infection or developing serious complications from HAV infection in these outbreaks and should be offered the hepatitis A vaccine in order to prevent or control an outbreak:
- People who use drugs (injection or non-injection)
- People experiencing unstable housing or homelessness
- Men who have sex with men (MSM)
- People who are currently or were recently incarcerated
- People with chronic liver disease, including cirrhosis, hepatitis B, or hepatitis C
- One dose of single-antigen hepatitis A vaccine has been shown to control outbreaks of hepatitis A and provides up to 95% seroprotection in healthy individuals for up to 11 years.
- Pre-vaccination serologic testing is not required to administer hepatitis A vaccine. Vaccinations should not be postponed if vaccination history cannot be obtained or records are unavailable.
CDC has provided outbreak-specific considerations for hepatitis A vaccine administration.
