Passport Health funktioniert nicht

Passport Health clients now have quick and easy access to vaccines received in our network of travel clinics, booster reminders, travel itineraries and much more. --Vaccine and Medical History: See which vaccines you've received, when you may need boosters and update any relevant medical history on-the-go through our secure app, designed with you in mind. --Travel Itineraries: Whether you're going to one destination or five, your personalized travel itineraries can be viewed through the Passport Health app.  View it through the app or download it on your device to see it where internet may not be available. --Appointment Management: See when and where your appointments are, create new appointments and more through our convenient app interface. --Yellow Fever Stamp: Many countries, especially in South America and Africa, require proof of yellow fever immunization.  Want to have the itinerary with you as you travel?  While the yellow card is the preferred method for many countries, have some extra peace of mind with yellow fever stamp information available a few taps away through the Passport Health app.
