Travel Vaccines Enter the Digital Age: Creating a Virtual Immunization Record

Area of Science:

• Public Health
• Health Informatics
• International Health Regulations

Background:

• Proof of immunization, like the International Certificate of Vaccination or Prophylaxis (ICVP), is required for international travel.
• The current paper-based ICVP has limitations: illegibility, loss, and damage.
• Digital health records offer potential advantages for public health and travelers.

Purpose of the Study:

• To propose a digital alternative to the paper-based International Certificate of Vaccination or Prophylaxis (ICVP).
• To explore the benefits and challenges of implementing a digital ICVP.
• To outline a development and implementation strategy for a digital ICVP.

Main Methods:

• Literature review on current vaccination certificate systems and digital health records.
• Analysis of limitations of the paper-based ICVP.
• Conceptualization of a digital ICVP system architecture and features.
• Discussion of implementation challenges and potential solutions.

Main Results:

• A digital ICVP offers enhanced availability, reliability, and data integration capabilities.
• Potential to include vaccine lot-specific information for improved traceability.
• Integration with existing immunization information systems is feasible.
• Verification at border crossings presents a key implementation challenge.

Conclusions:

• A digital ICVP presents a viable and advantageous complement to the existing paper-based system.
• Development and implementation require addressing verification challenges at international borders.
• Digital ICVP can improve traveler experience and public health surveillance.
