Vaccinations During Pregnancy

What’s the Difference Between Immunisation and Vaccination?

Most of us switch between using the words vaccination and immunisation, although they don’t mean exactly the same thing.

Vaccination means actually having a vaccine. This can be an injection (needle) or taken in via the mouth.

Vaccines contain small doses of either:

  • a live but weakened virus;
  • a killed bacteria or virus, or small parts of bacteria; or
  • a modified toxin produced by bacteria.

Immunisation means having a vaccine and then developing immunity to a disease.  This timeframe varies. There is generally a few weeks between having a vaccination, the immune system responding and then developing antibodies (resistance) to the disease.

What You Need to do Before You Conceive

If possible, start thinking about your vaccination cover before you conceive.  If you are planning a baby, checking your immunisation status is as important as any other aspect of your pre-conception health.

  • Have a check-up with your doctor or healthcare provider.
  • Find your vaccination record book, if you have one, and take it along with you.
  • Ask your doctor about having blood tests to check your immunity to vaccine preventable diseases. If, as a child, you did not complete the full primary course of your immunisations, you may need to have “catch-up” doses. If there’s any doubt, the general recommendation is to be immunised again.
  • Most importantly, check if you are fully immunised against these diseases: chickenpox, influenza, measles, mumps, rubella, diphtheria, tetanus and whooping cough.
  • Check with other people who live with you, your partner and who you’ll be having close contact with, about their own vaccination cover.
  • Aim to wait at least one month before conceiving after having vaccines which contain live viruses. These include measles, mumps and rubella (MMR) vaccine and the chickenpox vaccine.

But I’m Already Pregnant – Is it Safe For Me to be Vaccinated?

Many pregnant women worry about the safety of vaccinations during pregnancy. Though they know on one hand that some are recommended, many still have lingering doubts about the safety.

Immunisation during pregnancy serves a dual purpose – it helps to protect both the mother and her developing baby.

Read on to understand more about vaccinations and what you can do to protect yourself and your unborn baby.

Ideally, vaccination is avoided during pregnancy unless there is a risk to the woman and her unborn baby.

But there are a couple of exceptions to this rule.

It is recommended that all women should receive vaccinations for influenza and whooping cough* during every pregnancy.

*A whooping cough combination vaccine including tetanus and diphtheria protection - the adult dTpa  - Diphtheria-Tetanus-acellular Pertussis vaccine - is  recommended to be given in the third trimester of every pregnancy, ideally between 28 and 32 weeks gestation, but it can be given up until delivery. (Reference).

Serious side effects and allergic reactions to vaccinations are rare. The diseases themselves and the complications which vaccines protect against are far more common.

Remember too …

If pregnant women catch “the flu” they can become very sick and there is a higher risk of them developing complications. The influenza vaccine is protective for women and their baby for the first six months of life.

Influenza vaccine, otherwise known as “the flu shot” is free for pregnant women though you may need to pay a consultation fee to see your GP.  It can be given at any time during pregnancy. Autumn is generally the time when new flu vaccine strains are released for the community.

What’s the Risk with Infectious Diseases During Pregnancy?

Depending on the particular disease, the unborn baby could be affected.  And in the newborn period, before they’ve had a chance to build their own immunity and have their own vaccinations, very young children can also be harmed if their mother has an infection.

Some of the diseases which are particularly harmful to babies include rubella, chickenpox, measles, mumps and influenza. Whooping cough and influenza are also risky. It’s not just the diseases which are dangerous, but their complications as well.

What Else Can I do to Prevent Getting Sick?

  • Hand washing goes a long way in protecting all of us from disease. Get into the habit of washing your hands regularly, especially before eating, after toileting and handling animals.
  • Try not to put your hands to your face and touch your eyes, mouth or nose. Mucous membranes are a perfect entry point for microbes.
  • Try to stay away from people who are sick.
  • Avoid international travel, if possible, when you’re pregnant.
  • Eat healthy foods which support your immunity. Drink lots of water, aim for at least eight hours sleep a night and exercise regularly.

Where to go for Your Vaccinations

A tip
Vaccinations may be free under The National Immunisation Program Schedule (NIPS).

  • Speak with your GP or healthcare practitioner.
  • Ask your maternity care provider and/or the hospital where you plan to give birth.
  • Ask at your local community health centre.
  • Check with your local council about where immunisation clinics are held.
