Overview
Malaria and iron deficiency cause a significant burden of disease in Africa. Iron deficiency (ID) might affect immune responses to vaccination. In this double-blind randomized controlled trial, we aim to assess: (1) whether ID impairs R21/Matrix-M and measles (MR) vaccine response, (2) whether iron treatment at time of vaccination improves vaccine response.
Interventions
- Dietary supplement Iron syrup
Iron syrup administered daily from 6 to 10 months of age. - Dietary supplement Multivitamin syrup
Multivitamin syrup administered daily from 6 to 10 months of age. - Biological R21-Matrix/M Vaccine (malaria vaccine)
R21-Matrix/M vaccine administered in 3 doses at 7, 8 and 9 months of age. - Biological Measles-Rubella vaccine
Measles-Rubella vaccine administered at 9 months of age.
Primary outcome measures
- NANP-specific IgG [Time frame: At 10 months of age (1 month after the 3rd R21/Matrix-M dose)]
- anti- full lengths CSP IgG [Time frame: At 10 months of age (1 month after the 3rd R21/Matrix-M dose)]
- anti- C-terminal CSP IgG [Time frame: At 10 months of age (1 month after the 3rd R21/Matrix-M dose)]
- anti-measles IgG [Time frame: At 10 months of age (1 month after the first MR dose)]
Secondary outcome measures (12)
- NANP-specific IgG [Time frame: At 8 months age (1 month after the first R21/Matrix-M dose)]
- NANP-specific IgG [Time frame: At 9 months age (1 month after the second R21/Matrix-M dose)]
- anti- full lengths CSP IgG [Time frame: At 8 months age (1 month after the first R21/Matrix-M dose)]
- anti- full lengths CSP IgG [Time frame: At 9 months age (1 month after the second R21/Matrix-M dose)]
- anti-CSP IgA [Time frame: At 8 months age (1 month after the first R21/Matrix-M dose)]
- anti-CSP IgA [Time frame: At 9 months age (1 month after the second R21/Matrix-M dose)]
- anti-CSP IgM [Time frame: At 8 months age (1 month after the first R21/Matrix-M dose)]

- Haemoglobin [Time frame: 6 months of age]
- Haemoglobin [Time frame: 7 months of age]
- Haemoglobin [Time frame: 8 months of age]
- Haemoglobin [Time frame: 9 months of age]
