Headache after yellow fever vaccine

Headache, tiredness, muscle aches, and mild fever can happen as the body responds after vaccination. A mild headache that settles and is not accompanied by concerning features may be managed with rest, fluids, and symptom relief recommended by a pharmacist or clinician.

The timing and pattern matter. Tell the vaccinating clinic when the headache began, how it has changed, what you have taken for it, and whether you have other symptoms. This information helps distinguish a short-lived post-vaccination symptom from an illness that needs evaluation.

Rest in a cool, quiet setting, drink fluids regularly, and avoid alcohol if you are feeling unwell. Check with a pharmacist or clinician before using pain medicine if you have liver or kidney disease, stomach ulcers, take blood-thinning medicine, are pregnant, or have been told to avoid a particular medicine.

Keep your vaccination date and travel plan available. If symptoms continue, contact the clinic that gave the vaccine or another healthcare professional for personalised advice.

Get urgent medical care for a sudden extremely severe headache, headache with confusion, stiff neck, weakness, fainting, seizures, vision changes, breathing difficulty, or swelling of the face or throat. Prompt assessment is also needed if headache comes with persistent vomiting, a spreading rash, yellowing of the eyes or skin, or a fever that is getting worse. Mention the yellow fever vaccination and any recent travel when you seek care.

Ask which symptoms fit an expected vaccine response, what pain relief is suitable for you, and when you should be reviewed. If you are travelling soon, ask how the symptoms affect your travel plan and which details to give a clinician abroad.
