In the early 1990s, there was a scare over intramuscular vitamin K when a link was suggested between it and childhood leukaemia. This link has been disproven by further larger studies and there is now nothing to suggest that vitamin K is at all dangerous to babies. In fact it is almost certainly a very good thing. It is given to protect against the rare but catastrophic condition called haemorrhagic disease of the newborn, which can cause serious brain haemorrhage and damage in the baby. |
