The Flu Vaccine During Pregnancy: What You Need to Know

Getting the influenza (flu) vaccine is a common and strongly recommended way to protect both you and your baby during pregnancy.

This article explains the latest Australian guidance on flu vaccination during pregnancy and how to access it through MyHealth.

Why Pregnant People Are Urged to Get the Flu Vaccine 

Pregnancy changes the immune system, making it harder to fight infections like influenza. This puts pregnant people at higher risk of serious flu complications, including pneumonia, hospitalisation, and in rare cases, intensive care admission.

Flu infection during pregnancy may also increase the likelihood of adverse birth outcomes, such as preterm birth or low birth weight.

Vaccination not only protects the parent but also the baby. Maternal antibodies passed on during pregnancy help shield newborns from influenza in their first six months of life, before they are eligible for vaccination themselves.

Flu complications during pregnancy can lead to hospitalisation and early delivery—but the vaccine helps reduce that risk.

Is the Flu Vaccine Safe During Pregnancy?

The inactivated flu vaccine is considered safe at any stage of pregnancy. It does not contain live virus, so it cannot cause influenza in the parent or baby.

Australian health bodies, including the Department of Health, endorse flu vaccination as part of standard antenatal care, supported by decades of safety data. Pregnant people in many countries receive the vaccine routinely, and studies show no increased risk of complications for either the parent or baby.

Getting vaccinated is one of the most effective ways to protect both yourself and your child from influenza.

When Should You Get the Flu Shot While Pregnant?

It’s best to get the flu vaccine before or during the flu season to ensure optimal protection. The vaccine is safe at any stage of pregnancy - in the first, second, or third trimester. Immunity develops about two weeks after vaccination, so getting the flu shot early in the season gives you and your baby the most protection.

Can You Get the Flu Vaccine Free While Pregnant?

Pregnant people are eligible for a free flu vaccine under the National Immunisation Program (NIP). It’s available through MyHealth clinics and other participating GPs. Check your eligibility and book your appointment early, as demand increases when flu season approaches.
