Vaccination for the Treatment of Previously Untreated or Relapsed Follicular Lymphoma

• The dose of vaccine will depend upon how many of the participant's own tumor cells are available and at which point they join study. This Phase I trial is a "dose escalation" study. This means that participants will be enrolled in groups. Group 2 will receive a larger dose than Group 1. Group 3 will receive a larger dose than Group 2.
• The vaccine is administered in injections under and into the skin six times. Participants will receive vaccination shots once weekly for 3 vaccines, then every other week for 3 vaccines.
• After the first and fifth vaccinations, a small amount of the participants own lymphoma cells (killed) will be injected under the skin to see if their immune system will react against it and cause redness and swelling. A punch skin biopsy will also be performed at these injection locations.
• During the course of the study, we will also be drawing blood to evaluate immune cells and the effect that the vaccinations have on the participants immune system. During all treatment cycles a physical exam and questions about the participants general health will be performed.
• After the final treatment (approximately week 10) the participant will undergo "re-staging" to assess the status of their disease. If after completion of six vaccines, evaluation of the participant's disease reveals that it is stable or responding to the vaccine, and there is still vaccine available, they may be eligible to continue to receive the vaccines every two weeks until their supply runs out.
• After completion of the vaccinations, participants will come back for physical exams and blood tests every 3 months for 1 year and then once a year for fifteen years to monitor the effects of the vaccine.
