What should I do if I develop a fever after a tick vaccination? - in detail
A fever that appears after receiving a tick‑borne disease vaccine requires prompt attention.
First, record the temperature and note the time of onset. If the reading exceeds 38 °C (100.4 °F), begin supportive care:
- Increase fluid intake to prevent dehydration; water, electrolyte solutions, or clear broths are appropriate.
- Rest in a comfortable environment; avoid strenuous activity until the fever subsides.
- Administer an antipyretic such as acetaminophen or ibuprofen according to the recommended dosage for age and weight. Avoid exceeding the maximum daily limit.
Second, evaluate accompanying symptoms. Seek medical advice immediately if any of the following occur:
- Rash, especially if it spreads rapidly or involves the face and neck.
- Severe headache, neck stiffness, or visual disturbances.
- Persistent vomiting, diarrhea, or abdominal pain.
- Difficulty breathing, wheezing, or swelling of the throat or lips.
- Fever lasting longer than 48 hours despite antipyretic treatment.
Third, contact a healthcare professional for guidance. Provide the following information:
- Date and type of vaccination administered.
- Exact temperature readings and pattern over time.
- List of any medications taken, including over‑the‑counter antipyretics.
- Presence of additional symptoms listed above.
The clinician may recommend:
- Continued home management with antipyretics and hydration.
- Prescription of a short course of medication to address an inflammatory response.
- Laboratory tests to rule out infection or an adverse reaction.
- Observation in a medical facility if severe symptoms develop.
Finally, document the episode in the personal health record. Note the vaccine batch number, date of administration, fever onset, interventions taken, and outcomes. This record assists future healthcare providers in assessing vaccine tolerance and planning subsequent immunizations.
