- Hematology
- Haemoglobin \<9.0 g/dL or \<5.59 mmol/L
- Absolute Neutrophil Count (ANC): \< 1000/mm3 or \< 1.0 x 109/L
- Absolute Lymphocyte Count (ALC): ≤ 500/mm3 or ≤ 0.5 x 109/L
- Platelets: ≤ 90,000 ≥ 550,000/mm3 or ≤ 90 x 109 ≥ 550 x 109/L
- Chemistry
- Creatinine: \> 1. 1 x ULN
- AST: \>2.6 x ULN
- ALT: \>2.6 x ULN
- Urinalysis: abnormal dipstick confirmed by microscopy
- Protein 2+ or more
- Blood 2+ or more (not due to menses)
- History or evidence of autoimmune disease.
- Positive for Hepatitis B surface antigen (HbsAg), positive for antibodies to Hepatitis C virus (HCV) or active syphilis.

- Volunteers will be enrolled regardless of schistosomiasis infection status. Volunteers with high S. mansoni egg count of \>2000 eggs per gram of stool at screening will be treated before vaccination. Volunteers with low S mansoni egg count of \<2000 eggs per gram of stool at screening will be asked to forgo treatment until after completion of week 24 visit of the trial. Volunteers with other helminth infections at screening will also receive treatment before vaccination.
