Summary
Background Results of randomised controlled trials of newborn (age 1–3 days) vitamin A supplementation have been
inconclusive. The WHO is coordinating three large randomised trials in Ghana, India, and Tanzania (Neovita trials).
We present the findings of the Neovita trial in Ghana.
Methods This study was a population-based, individually randomised, double-blind, placebo-controlled trial in the
Brong Ahafo region of Ghana. The trial participants were infants aged at least 2 h, identified at home or facilities on
the day of birth or in the next 2 days, able to feed orally, and likely to stay in the study area for at least 6 months. They
were randomly assigned (ratio 1:1) to receive either one oral dose of vitamin A (50 000 IU) or placebo immediately
after recruitment. The research team and parents of the infants were masked to treatment assignment. Follow-up
home visits were undertaken every 4 weeks, when data were recorded for deaths, facility use, and care seeking. The
primary outcome was post-supplementation mortality to 6 months of age. Analysis was by intention to treat. Potential
adverse events were recorded at 1 and 3 days after supplementation. This trial is registered with the Australian
New Zealand Clinical Trials Registry (ANZCTR)CTRN12610000582055.
Findings We assessed 26 414 livebirths for eligibility between Aug 16, 2010, and Nov 7, 2011. We recruited
22 955 newborn infants, with 11 474 randomly assigned to receive vitamin A and 11 481 to receive placebo. Loss to
follow-up was low with vital status at 6 months of age reported for 22 698 (98·9%) infants. We recorded
278 post-supplementation deaths to 6 months of age in the vitamin A group (mortality risk 24·5 in 1000 supplemented
infants) and 248 deaths in the placebo group (mortality risk 21·8 per 1000 supplemented infants), relative risk (RR)
1·12 (95% CI 0·95–1·33; p=0·183) and risk difference (RD) 2·66 (95% CI –1·25 to 6·57; p=0·18). Adverse events
within 3 days of supplementation did not differ by trial group. 122 infants died in the first 3 days after supplementation;
70 (0·6%) in the vitamin A and 52 (0·5%) in the placebo group (risk ratio [RR] 1·35, 95% CI 0·94–1·93, p=0·102).
53 infants were reported to have a bulging fontanelle; 32 (0·3%) in the vitamin A group and 21 (0·2%) in the placebo
group (RR 1·53, 0·88–2·62, p=0·130).
Interpretation The results of this trial do not support inclusion of newborn vitamin A supplementation as a child
survival strategy in Ghana.

Introduction
When vitamin A supplements are given to children they
substantially reduce mortality at 6–59 months but they
have no effect on mortality in children aged 1–5 months.
1–5
Whether newborn (age 1–3 days) vitamin A
supplementation can reduce neonatal (age 1–28 days)
and infant mortality has been of substantial interest.
However, results of randomised trials have been
inconclusive.
6–13
A WHO technical consultation in
December, 2008, stated that the evidence base to make a
public health recommendation about neonatal vitamin A
supplementation was insufficient.

Three additional
randomised placebo-controlled trials were recommended
(two in Africa and one in Asia). The consultation
recommended that the trials should be done in areas
with high infant mortality and low HIV prevalence. The
consultation also recommended that the trials exclude
populations with adequate vitamin A status and exclude
areas with high levels of vitamin A fortification.

WHO secured funding to coordinate randomised trials
in three sites. Ghana, India, and Tanzania were selected.
The primary objective of all three trials was to see if a
single vitamin A oral dose of 50 000 IU given to newborn
infants on the day of birth or in the next 2 days could
reduce post-supplementation mortality by at least 15% in
the first 6 months of life. Secondary objectives were to:
assess effects on post-supplementation mortality to 28 days
and 12 months of age; assess effects on risk of hospital
admission to 6 months of age; document any potential
adverse effects in the 3 days after supplementation; and to
