Forensic examination of security features of the CDC-issued COVID-19 vaccination card and suggested improvements to minimize counterfeiting

During the COVID-19 pandemic, the United States released the CDC-issued vaccination card to document the status of immunizations. It eventually was used as a verification system to allow patrons to safely access public venues. This is/was apparently a simple printed piece of paper with minimal security features which made it an easy target for counterfeiters with little expertise required. Those unvaccinated who wished to enter areas that required proof of the COVID-19 vaccine were soon finding alternative illegal methods to do so which led to public health concerns. This research was divided into two parts. Part A aimed to forensically identify the security features with a video spectral comparator and a stereomicroscope. Ten known blank cards were collected directly from dispensaries that administered the vaccine and 68 unknowns from individuals who received the COVID-19 vaccine. Part B aimed to evaluate the authentication systems employed by countries outside the United States to propose a model on how the vaccination card could be improved and what security features should be included for future instances requiring proof of immunization. The results revealed the CDC document was produced with minimal security features making the document prone to counterfeiting. Furthermore, based on the information collected from other countries' vaccination certificates, it is recommended to develop a dual authentication system, with digital and printable aspects, that contains a QR code linked to a database. Other security features may include a non-optical brightener substrate, security fibers, a watermarked logo, offset printing, and a geographical color-coded system.

Automated summary

The CDC-issued vaccination card used during the COVID-19 pandemic had minimal security features, making it vulnerable to counterfeiting. The research suggests the development of a dual authentication system with digital and printable components, including a QR code linked to a database, to enhance security.
