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)
A master randomization sequence list will be prepared by off-site a priori. The randomization lists will be used for individually packaging and labeling the vitamin A/placebo doses for each enrolled newborn. Two capsules will be packed in a blister pack, one for the dose and the second for the backup dose. The blister packing, shape, size and color of the vitamin A and placebo capsules will be similar. Labels will be printed with the site and subject ID. Each participant will be assigned to the next regimen number in sequence at enrollment.

After becoming aware of a birth (when visiting the health facilities daily) or when notified of a birth by a key informant in the community, the Enrollment Research Assistant (ERA) will meet the newborn's parents between two hours and two days after birth. The ERA will do that either at the facility where birth as occurred or at the infant's home. The ERA will administer the enrollment consent form to mothers at this time if they were not identified to participate in the study through pregnancy surveillance. If the mother provides informed written consent to participate in the study, the newborn will be screened for the eligibility and exclusion criteria and enrolled in the study. Enrollment information such as date of birth, multiple births, birth weight, sex, and timing of initiation of breastfeeding will be collected. If the infant is eligible for enrollment, an identification number or a subject ID will be allocated and the vitamin A or placebo capsule administered.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomization list will be prepared off-site, under the responsibility of the World Health Organization (WHO). The method of sequence generation to be used is permuted block randomization.
