Baby Hints & Tips

Influenza immunisation in pregnancy

During pregnancy the risk of serious complications from influenza, the flu, is greatly increased.  The best way to protect yourself against the flu is by immunising against it.  In Australia the influenza immunisation is free for pregnant women at your GP.

Influenza immunisation is safe in all stages of pregnancy and when trying to conceive.  The Royal Australian and New Zealand College of Obstetricians and Gynaecologists strongly endorse routine vaccination of all pregnant women and those planning pregnancy against influenza.

influenza immunisation in pregnancyWhat is influenza?

Influenza is a potentially life-threatening viral infection.  The flu is spread by droplets when someone sneezes, coughs or touches an infected surface.

Proteins of the virus frequently change resulting in new strains of the disease.  As a result a new immunisation is needed yearly for every influenza season.

Risks of influenza in pregnancy and to newborns

Pregnant women with the flu are more likely than the general population to experience serious disease and death.   This is due to pregnancy changes including to the heart, lungs and immune system.  The flu can also result in premature labour and delivery.

Influenza in an unborn or newborn child can cause serious problems and even death.  Babies aged under 6 months of age are more likely than older children to be hospitalised from influenza.

When should I immunise against the flu in pregnancy?

Immunisation is ideal early in the influenza season (April/May) however you should immunise at any time during the season while vaccine is available.

Does influenza immunisation protect an unborn baby?

A child can not have the influenza immunisation until they are 6 months old.  Antibodies produced after a pregnant women is immunised transfer across the placenta and are an effective way to protect a baby in their first 6 months of life.   Antibodies are also transferred through breastfeeding.

Risks of influenza immunisation

Influenza immunisation has been shown to be safe in all stages of pregnancy.  There is no evidence at this point to show that there is an increased risk of side effects for a pregnant woman or their baby.

The influenza immunisation does not contain live virus and so can not give you the flu.  Side effects that can occur include soreness at the injection site, fever, tiredness and muscle aches.  A full list of potential side effects from influenza immunisation is available here.

Other ways to protect against the flu

  • Cover your mouth when coughing or sneezing
  • Dispose of dirty tissue immediately
  • Wash your hands often, especially after coughing or sneezing
  • Stay away from those who are sick
  • Ask everyone who cares for your baby to have the influenza immunisation (at least 2 weeks before they are around your child)
