Randomized Controlled Trial
Vitamin A supplementation and BCG vaccination at birth may affect atopy in childhood: long-term follow-up of a randomized controlled trial.

We aimed to determine whether neonatal BCG vaccination, vitamin A supplementation and other vaccinations affect atopy in childhood. ⋯ Clinicaltrials.gov NCT 01420705.
