Why would someone need a rhogam shot after giving birth?
A rhogam shot is necessary both during pregnancy and after birth for the mother if she has a different rh blood type then the baby. For example if a mother has a rh negative blood type and the baby is a rh positive blood type her body may have an immune response if any blood gets mixed at any point of the birth or pregnancy. The body will then think it's sick and try to fight off an illness that isn't there, causing issues for future pregnancies and other health issues. The rhogam shot helps prevent the body from developing rh positive antibodies. Keep the mother healthy and safe for future pregnancies.
