Proof of Vaccination Must Now Include Proof of Booster

Real Vaccination ID provides digital and physical proof of COVID-19 Vaccination Status, Booster Shots or Legal Waiver Requests

August 27, 2021


WILMINGTON, NC—With Pfizer and its partner BioNTech filing paperwork seeking approval for a booster of its mRNA-based COVID-19 vaccine, Comirnaty, and Moderna not far behind, the task of proving vaccination or waiver status to comply with the growing number of vaccine mandates is now more complicated than ever. But one solution – CastleBranch’s card – was specifically designed to address this long-term need, and is now available to schools, businesses and individuals as a way to easily show proof of a booster shot, vaccination or waiver status.


To obtain their first card, individuals are asked to provide documentation to prove their vaccination status or legally permissible waiver request. Once validated, a driver’s license-sized card featuring highly sophisticated anti–fraud technology is issued to the individual that includes their name, address, date of birth, physical identifiers, photo, and a QR code. Using the QR code on the back of the card, along with a unique access code and PIN number, third parties presented with this information can access digital copies of primary–source documentation to confirm status.


Updating the cards to reflect booster shots is just as simple. When someone receives a booster, they can submit their documentation to CastleBranch, whose team of experts will verify the documentation. CastleBranch houses the new information in their protected digital space as a way to help prove status.


“Our understanding of the COVID-19 virus changes with each passing day, requiring a response that also adapts and grows,” said Brett Martin, CastleBranch CEO. “With variants come boosters, which requires a form of vaccination proof that can be updated over time. Our cards were designed to respond to these emerging realities, helping people and organizations as they continue to navigate the new normal.”


CastleBranch launched RealVaccinationID.comin January 2021 to save clients in the education, healthcare, and business sectors from the logistical, legal, and liability pitfalls that come with allocating inexperienced internal resources toward implementing a comprehensive vaccination and waiver system. CastleBranch experts review all documentation, create medical and religious waiver processes and forms, and successfully handle sensitive, private information without running afoul of strict state and federal data handling rules and regulations.


The cardholder controls when and with whom his or her data is shared. CastleBranch will never distribute the private data gathered for cards to third parties.


CastleBranch is one of the leading providers of vaccination and immunization tracking in the United States. With 25 years’ experience, the company has tracked, reviewed, and/or stored over 35 million medical documents for a majority of healthcare education programs across the nation.
