What is maternal immunization?
- Maternal immunization refers to the process of vaccinating a pregnant woman so protective antibodies can be passed to the baby through the placenta before birth.
- During pregnancy, your body naturally passes on antibodies that protect your baby against bacteria and viruses in the first few months of life, before they’re old enough to develop their own protection.
- It’s a standard practice to immunize pregnant women to give the baby additional antibodies that help protect against a specific disease.
- Many pregnant women choose to receive a vaccine while they are pregnant so their baby doesn’t have to receive a shot themselves after birth.
Maternal immunization is a choice pregnant women can make to help protect their babies.
