Are Flu Vaccines Safe During Pregnancy?
In this guide, we will know why getting vaccinated is an important step in keeping you and your baby healthy.
Why Pregnant Women Are Advised to Get the Flu Vaccine
Pregnant women are more at risk of developing severe illness if they catch the flu, which can lead to pneumonia, premature birth, or low birth weight. According to the NHS, flu vaccination significantly lowers these risks and provides crucial protection for both mother and child.
How Flu Affects Pregnancy
- Increases the risk of hospitalisation
- Can cause respiratory complications
- May affect foetal growth and wellbeing
Benefits of Flu Vaccination During Pregnancy
- Strengthens the immune system against circulating strains
- Reduces the likelihood of serious illness
- Protects the baby in the first few months after birth
Is the Flu Vaccine Safe During Pregnancy?
Yes. The flu vaccine in pregnancy is safe to receive at any stage, according to the NHS — whether in the first, second, or third trimester. The version offered through the NHS flu vaccination programme is an inactivated vaccine, meaning it cannot cause flu infection.
Safety Evidence and Monitoring
- Backed by extensive studies and global monitoring
- No increased risk of miscarriage or birth defects
Common Concerns Addressed
- Safe to take alongside the whooping cough vaccine
- Millions of pregnant women have been vaccinated safely worldwide
What Are the Side Effects of the Flu Vaccine?
The side effects of the flu vaccine are generally mild and short-lived, showing your body is building protection.
Common Side Effects

- Mild fever, fatigue, or muscle aches for 1–2 days
Rare or Serious Reactions
- Serious allergic reactions are extremely rare
- Always seek medical help if breathing difficulties or swelling occur
How the Flu Vaccine Protects Your Baby
After vaccination, your antibodies pass through the placenta, protecting your baby for the first few months of life. This early protection is vital until your child can receive the children’s flu vaccination themselves.
When and Where to Get the Flu Vaccine
The flu jab is available free on the NHS from GPs and participating pharmacies. It’s best to get vaccinated before flu season peaks, but it’s safe at any point during pregnancy.
