General information, not an individual diagnosis. Ask a healthcare professional if you are unsure about your situation.
You develop a fever before a vaccination appointment. Contact the professional before travelling. Explain what has changed and ask whether to keep or postpone the appointment rather than deciding from general information alone.
For flu, Ameli states that an acute infectious illness with fever leads to postponement until recovery. This concerns your condition when vaccination takes place; it is not a remote assessment of your case.
Santé publique France explains that a minor illness, even with slight fever, does not automatically rule out vaccination. Acute illness with high fever and more pronounced symptoms may lead to postponement. The professional assesses that distinction.
Prepare useful details: when symptoms began, your temperature if measured and the planned vaccine. Avoid setting a universal threshold or calculating a return date yourself from information online.
Temporary postponement differs from a lasting contraindication. Ask about the next step and how to get back in touch. If symptoms concern you, seek suitable medical advice without waiting for vaccination.
If a new appointment is agreed, use the vaccination block for flu or Covid-19 as appropriate. Conditions are checked before vaccination. Mon bilan prévention remains a separate appointment.

Flu and Covid-19: the 2026–2027 campaign
The national flu and Covid-19 vaccination campaign starts on 13 October 2026. In Doctolib, choose “Vaccination antigrippale (Grippe)” or “Vaccination COVID-19” for the vaccination you want to discuss.
Bring your carte Vitale and, for flu, your coverage voucher if you have one. The professional checks the recommendations and coverage conditions that apply to you.
The pharmacy checks whether vaccination and coverage apply based on the vaccine, your age and your circumstances.
