Eligibility
Key inclusion criteria
Healthy infants (greater than 3rd percentile for height and weight) at enrollment living within the catchment area of
the participating polyclinics.
Minimum age
4 Months
Maximum age
5 Months
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Infants less than 3 percentile for height and weight, residence outside the catchment area, or families expecting
to move away during the study period, will be excluded. A diagnosis, suspicion or treatment of
immunodeficiency disorder (either in the participant or in a member of the immediate family) will render
the newborn ineligible for the study. Infants of mother age below legal age (<18 years) or with mentally
incapacity will not be eligible to participate.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Mothers or caretakers will be invited to participate when they present for the 2-month routine immunization visit. Infants are enrolled following the 2-month clinical assessment visit. Study envelopes will be used to determine which study vaccines a study participant will receive.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The use of random number generator (for randomization) will be used allocate study participants to a study arm, and its use will attempt to minimize/avoid bias.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?
