In this early draft, we describe a user-centric, card-based system for vaccine distribution. Our system makes use of digitally signed QR codes and their use for phased vaccine distribution, vaccine administration/record-keeping, immunization verification, and follow-up symptom reporting. Furthermore, we propose and describe a complementary scanner app system to be used by vaccination clinics, public health officials, and immunization verification parties to effectively utilize card-based framework. We believe that the proposed system provides a privacy-preserving and efficient framework for vaccine distribution in both developed and developing regions.

MIT SafePaths卡（MiSaCa）：使用打印代码增强纸质疫苗卡

在此早期草案中，我们描述了一种以用户为中心，基于卡的疫苗分发系统。我们的系统利用经过数字签名的QR码及其在阶段性疫苗分发，疫苗管理/记录保存，免疫验证和后续症状报告中的用途。此外，我们提出并描述了一个补充的扫描仪应用程序系统，该系统将由疫苗接种诊所，公共卫生官员和免疫验证人员使用，以有效利用基于卡的框架。我们认为，该提议的系统为发达和发展中地区的疫苗分发提供了一个保护隐私的有效框架。
