1 Clinical Trials for Various Conditions
Background: People who have cancer tend to get sick more often. This is in part because of the cancer treatments they get. Because of this, they may get shingles. Scientists had thought people with chronic lymphocytic leukemia (CLL) should not get the shingles vaccine. Now there is a new shingles vaccine that is not live and cannot cause shingles. The new shingles vaccine may protect people with weak immune systems from getting shingles. This is currently shown to be safe to give people 50 years and older to prevent shingles. Researchers want to test how safe the vaccine is and how it works in people with CLL. Objective: To learn how a new shingles vaccine works in people who have chronic lymphocytic leukemia or small lymphocytic lymphoma (SLL). Eligibility: Adults ages 18 years and older with CLL or SLL who are not being treated for CLL or who are getting certain treatments. Design: Participants will be screened with a chart review or through another protocol. Visit 1 At visit 1, participants may have a pregnancy test, blood test, or physical exam. Pregnant participants cannot be in the study. Eligible participants will get the shingles vaccine as an injection. Participants will receive a diary and write down any symptoms they have for 7 days after the vaccines. Visit 2 Visit 2 will be 3 months later. Participants will have blood taken and get another dose of the vaccine. Participants will receive a diary and write down any symptoms they have for 7 days after the vaccines. Visit 3 Visit 3 will be 3 months after visit 2. Participants will have blood taken. Participants may be able to get an additional vaccine the same day as the shingles vaccine.
