Act as an expert US Immigration Consultant and Medical Liaison. I need a detailed preparation guide for my USCIS Immigration Medical Exam (Form I-693). 

My current profile is as follows:
- Age: [AGE]
- Country of Origin: [COUNTRY_OF_ORIGIN]
- Vaccination History: [VACCINATION_HISTORY]
- Known Medical Conditions: [MEDICAL_CONDITIONS]
- Civil Surgeon Appointment Date: [APPOINTMENT_DATE]

Please provide a structured response covering the following:
1. **Vaccination Requirements**: Based on my age and profile, list the specific CDC-required vaccines I likely need (including COVID-19, Flu if seasonal, MMR, etc.).
2. **Document Checklist**: A list of items I must bring to the Civil Surgeon (ID, records, forms).
3. **The Examination Process**: A step-by-step walkthrough of what happens during the physical, blood tests (TB, Syphilis, Gonorrhea), and mental health evaluation.
4. **Potential Red Flags**: Analyze my [MEDICAL_CONDITIONS] and explain if they fall under 'Class A' (inadmissible) or 'Class B' conditions, and how to prepare documentation to mitigate issues.
5. **Form I-693 Logistics**: Instructions on handling the sealed envelope, validity periods, and submission timing.
