It is very common and normal to experience a mild fever and localised pain after a typhoid vaccine; this indicates your immune system is responding well. To relieve these symptoms, you can take an over-the-counter pain reliever like paracetamol (acetaminophen) or ibuprofen. Please follow the dosage instructions on the package carefully. Applying a cool, damp cloth to your thigh can also help soothe the injection site. These side effects typically resolve within 24 to 48 hours. If your fever rises significantly or the pain worsens after a few days, please consult a healthcare professional for advice.
