Summary

The purpose of this study is to compare how the body's immune system reacts to a vaccine against smallpox infection, called Modified Vaccinia Ankara (MVA) and to evaluate the safety of this vaccine. Study participants will include 24 adults, ages 18-60 years, who have undergone a stem cell transplant more than 2 years ago. Study procedures will include a physical exam, blood samples, heart activity assessments, and urine samples. Participants will be assigned to 1 of 2 possible study vaccine groups. The participants will receive 1 of 2 possible vaccine doses or placebo (substance containing no medication) 28 days apart. Participants will make at least 8 visits to the clinic during the course of the study; additional visits may be needed if the participant experiences side effects from the vaccine. Participants may be involved in study related procedures for about 6 months.

Conditions

  • Variola Major (Smallpox)

Interventions

DRUG

Placebo

Sterile saline (0.9%).

BIOLOGICAL

MVA-BN

The smallpox vaccine is a liquid frozen solution formulated to contain 0.605 mg Tris and 4.090 mg sodium chloride (NaCl) per 0.5 mL dose. The concentration of the virus will be 1 X 10\^8 tissue culture infectious dose 50 (TCID 50) per 0.5 mL dose and may be diluted in a solution of 0.9% saline prior to vaccination. Smallpox vaccine administered in 2 doses approximately 28 days apart in one of the following doses: 1X10\^7 or 1X10\^8 TCID 50.
