How to Relieve Pain After Vaccination in Babies

Vaccinations are an important part of protecting your baby from serious illnesses. While vaccines are safe and effective, it is common for babies to experience some mild pain, redness or swelling at the injection site afterward. Knowing how to relieve pain after vaccination can help you comfort your baby and support their recovery.

What to Expect After Vaccination

After a vaccination, your baby may have a sore or tender arm or thigh where the injection was given. They might be a little unsettled, cry more than usual, or have a slight fever. These symptoms usually appear within a few hours and improve within one to two days.

Why Does Pain Occur After Vaccination?

Pain after vaccination is caused by the body’s immune response to the vaccine. The injection itself can irritate the skin and muscle, causing temporary discomfort. Mild swelling or redness is a sign that the body is building protection.

How to Relieve Pain After Vaccination

Holding and cuddling your baby can provide comfort and reassurance. Skin-to-skin contact is especially soothing and helps reduce distress.

Applying a cool, damp cloth gently to the injection site can reduce redness and ease soreness. Avoid rubbing or applying any creams unless advised by your healthcare provider.

If your baby is unsettled or uncomfortable, giving their usual dose of infant paracetamol (such as Calpol) can help relieve pain and reduce fever. Always follow the dosing instructions carefully and consult your pharmacist or GP if you are unsure.

Feeding your baby during or shortly after vaccination can help calm them and distract from discomfort.

Ensure your baby gets plenty of rest and keep them hydrated with regular breastfeeding or bottle feeds.

Avoid strenuous activity for the next 24 hours, but gentle play is fine.

When to Seek Medical Advice

Contact your GP or health visitor if your baby has a high fever (over 38°C), persistent crying lasting more than three hours, difficulty breathing, or if you notice unusual swelling, rash or other concerning symptoms.

If you are worried about your baby’s reaction to a vaccine at any time, seek advice from a healthcare professional.

Emotional Impact

Seeing your baby in pain can be upsetting for parents and carers. Remember that mild discomfort is normal and short-lived. Support from family, friends and health professionals can help you feel more confident in caring for your baby.

Final Thoughts

Pain after vaccination in babies is common but usually mild and temporary. Comforting your baby with cuddles, applying a cool compress, and using infant paracetamol if needed can help ease discomfort. Always follow professional advice and reach out for support if you have any concerns.
