The human body reacts to infection or injury with an inflammatory response, which kicks off with the acute phase response. The acute phase response helps the body to fight the infection. It is characterized by many altered physiological processes, including changed availability of vitamins and minerals. Recently, we found that delivery in itself causes a major acute phase response. We have formed the hypothesis that the acute phase response initiated by delivery prevents the high dose vitamin A supplement given to the mother directly after delivery from being absorbed and from being available for breast milk. If this is true, the current WHO recommendation to give the vitamin A within the first 6 weeks post-partum should be changed to giving the vitamin A 4 - 6 weeks post-partum instead, to allow the acute phase response induced by delivery to fade.
