Newborn infants are deficient in vitamin K. and this injection prevents your infant from abnormal bleeding.”

Vitamin K is necessary for the body to synthesize coagulation factors. Vitamin K is administered to the newborn infant to prevent abnormal bleeding.

The infants bowel does not have support the production of vitamin K until bacteria adequately colonizes it by food ingestion.
