CERN Health Insurance Scheme (CHIS)

As an intergovernmental organization, CERN has its own health insurance: the CERN Health Insurance Scheme (CHIS).
The main purpose of the CHIS is to safeguard its Members against the financial consequences of illness, accidents and maternity by providing reimbursement of expenses arising from medical treatment. A Third-Party Administrator operates the CHIS: UNIQA, whom you may contact for further information and advice, for queries concerning your coverage, the calculation of your reimbursements or your membership.

France : how to obtain your QR code

  • You have been vaccinated in a vaccination centre:  

1) You were vaccinated after May 3rd, 2021: no problem, your vaccination certificate contains the QR code.  

2) You received your two doses of vaccine before May 3rd :  after the title "patient code", your vaccination certificate indicates a 9-letter code, to obtain the QR code you can go back to your vaccination centre and ask them for the QR code. You can also, with your 9-letter code, go to your pharmacist who will consult VACCIN COVID and give you your QR code

  • You have been vaccinated by your doctor (with the AstraZeneca vaccine):

They may not be able to give you a QR code.  

The solution could have been to call the toll-free number 0800 08 71 48 or send an email to, unfortunately this service does not yet work for people with a foreign health insurance fund although they assured us that they are looking for solutions.  

Important information on reimbursement of COVID-19 tests -Updated September 17, 2021- 
Since the COVID-19 pandemic began, the CERN Health Insurance Scheme (CHIS) has reimbursed various types of test. As of 1 October 2021, CHIS will align with the measures in place in the Host States, and tests taken to obtain a COVID certificate  will no longer be reimbursed for those over 16 years of age without a medical prescription or a medical certificate (for people who cannot be vaccinated on medical grounds). The conditions for reimbursement are different for each type of test. For more information, click here.
