Additional precautions: Seek medical advice urgently if you develop a high fever, severe headache, pain behind the eyes, rash, vomiting, bleeding gums, unusual bruising, severe stomach pain, or feel seriously unwell during travel or after returning home. The dengue vaccine may not be suitable for everyone and is usually considered for travellers who have had, or may have had, dengue before.
