Your baby's 6-week immunisations

Your baby’s first big round of vaccinations comes at around 6 weeks of age, as part of Australia’s National Immunisation Program. It’s a milestone that can feel daunting for new parents, but immunisation is one of the most important things you can do to protect your baby. Here’s what to expect and how to make it easier.

Why it matters. Vaccines protect your baby against serious, sometimes life-threatening infectious diseases — like whooping cough (pertussis), diphtheria, tetanus, hepatitis B, polio, Hib, pneumococcal and rotavirus — at an age when they’re most vulnerable. Young babies can become very unwell from these illnesses, so early protection genuinely saves lives. Vaccination also protects other vulnerable people in the community.

When and what. The Australian schedule gives vaccines at birth (hep B), 6 weeks, 4 months, 6 months, 12 months, 18 months and beyond. The 6-week visit is the first main round, usually given as a few injections plus an oral (drinkable) rotavirus vaccine. Your provider will tell you exactly which vaccines your baby is due.

Where to get them. Childhood immunisations are free under the National Immunisation Program. You can have them done at your GP, many council/community immunisation clinics, or Aboriginal Medical Services. Book ahead, and it’s worth timing it around a feed so your baby is settled.

What happens on the day. A nurse or doctor gives the injections quickly, usually in your baby’s thighs. It’s over fast. Feeding or cuddling your baby during or straight after, and holding them close, comforts them and can reduce the distress. Bring their baby health record book so it can be updated, and you’ll usually be asked to wait about 15 minutes afterward just in case.

Common reactions (all normal). After vaccines, it’s common for babies to be a bit unsettled, sleepy or grizzly, have a mild fever, or a red, sore lump where the needle went in for a day or two. These are normal signs the immune system is responding. Extra cuddles and feeds, and keeping your baby comfortable, help. Ask your provider about using paracetamol if needed.

When to seek help. Serious reactions are very rare, but contact your doctor (or seek urgent care) if your baby has a high fever that won’t settle, a reaction that seems severe or unusual, persistent inconsolable crying, or any signs of a serious allergic reaction (difficulty breathing, swelling) — call 000 for that. Trust your instincts and get advice if you’re worried.

If your baby is unwell or premature. If your baby is sick with a fever on the day, ask whether to proceed or reschedule (a minor cold is usually fine). Premature babies are still vaccinated according to their actual age (from birth), not their due date — it’s especially important for them. Check with your provider about anything specific to your baby.

Feeling nervous is normal. It’s hard to watch your baby have needles, and many parents feel anxious or upset — that’s completely normal, and it passes quickly for your baby. Focus on the comfort you can give (feeding, cuddling, your calm voice), and remember you’re doing something powerfully protective for them.

Keeping track and staying up to date. Staying on schedule matters, so your baby gets protection at the right ages — set reminders, and use your state’s immunisation register/reminders if available. Being up to date is also linked to some family payments in Australia, and is often required for childcare down the track. If you fall behind (illness, travel, or life simply happening), your GP can arrange a catch-up — it’s never too late to get back on track, so just book in.

Your baby’s 6-week immunisations are a safe, free and vital step in keeping them healthy. Book ahead, comfort your baby through it, expect a day or two of being a bit unsettled, and keep the record book updated. If you ever have questions about the schedule or a reaction, your GP or child health nurse is there to help.
