Why do you have to a rh factor shot?

The Rh factor shot, also known as the RhoGAM shot, is given to Rh-negative pregnant women to prevent Rh disease in their future pregnancies. Rh disease is a condition in which the mother's immune system attacks her fetus's red blood cells. This can lead to serious health problems for the fetus, including anemia, jaundice, and even death.

Rh disease occurs when the Rh-negative mother's immune system is exposed to Rh-positive blood from her fetus. This can happen during pregnancy or delivery. Once the mother's immune system is sensitized to Rh-positive blood, it will produce antibodies that attack the fetus's red blood cells.

The Rh factor shot is a monoclonal antibody that prevents the mother's immune system from being sensitized to Rh-positive blood. The shot is given at 28 weeks of pregnancy and again within 72 hours of delivery if the baby is Rh-positive. The shot is also recommended after a miscarriage or abortion.

The Rh factor shot is a safe and effective way to prevent Rh disease. It is important for all Rh-negative pregnant women to receive the Rh factor shot to protect their future pregnancies.
