Immunization

It is important to have your immunizations up-to-date as part of your pregnancy plan. Your health care provider can review your immunization status and you can have a discussion about any additional vaccines that might benefit you and your baby.   While most vaccines are safe to receive during pregnancy, there are some that are best given at least four weeks before pregnancy. 

Immunization (vaccination) is an effective and safe way to protect you and your baby from certain infections you may be exposed to once pregnancy occurs. Pregnant individuals are at greater risk than non-pregnant individuals for more severe illness from some diseases that can be prevented by vaccines. Some of these infections can also cause permanent health problems if the baby is exposed to them during pregnancy. Vaccinations will protect the baby after birth, while the baby is too young to get their own vaccines.

While most vaccines are safe to receive during pregnancy, there are some that are best given at least four weeks before pregnancy.
