Bos-Veneman NGP, et al. - Researchers performed a randomised controlled trial to evaluate the effectiveness and potential side effects of formula feeding to reduce pain during vaccination among infants. They compared infants who drank formula feeding before, during and after vaccination with infants who did not to evaluate pain experienced during vaccination. Formula feeding reduced vaccination pain in the recovery phase in full-term born infants receiving their first vaccinations between ages 4 and 10 weeks with no adverse effects in line with findings of previous studies regarding breastfeeding. They suggested that experts should discuss this non-costly and feasible pain-reducing intervention with guardians of infants who receive vaccinations.
