Summary:

      Background:

      People with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) tend to
      get infections more easily. This is because their immune systems are weakened. Hepatitis B is
      a virus that can be transmitted when body fluids from an infected person enter the body of an
      uninfected person. This virus can be dangerous for people with leukemia and lymphoma.
      HEPLISAV-B is a new hepatitis B vaccine. Researchers want to see if it can protect people
      with CLL/SLL from getting hepatitis B.

      Objective:

      To learn how HEPLISAV-B works in people who have CLL or SLL.

      Eligibility:

      Adults 18 years and older with CLL (or SLL). They must be getting no treatment for their CLL,
      or getting ibrutinib or acalabrutinib for it.

      Design:

      This study lasts 6 months from the date of first vaccination.

      Participants may be screened with:

      Physical exam

      Blood tests

      Pregnancy test

      Visit 1

      Participants will get blood drawn and the study vaccine. It will be given as an injection. If
      they get any symptoms within 7 days of the vaccine, they will write them in a diary.

      Visit 2

      After 3 months, participants will come back to the NIH to get another blood draw and the
      second vaccine dose.

      Visit 3

      Participants will return 3 months after the second vaccine dose was given. They will have
      blood drawn.
