One component of this system must be an electronic exposure registry that can track vaccine administrations. Similar to other mass vaccination campaigns, 2 public health authorities will need to control distribution and roll out a nationwide campaign. Since the 2009 to 2010 H1N1 pandemic, many models have utilized pharmacies to administer influenza vaccine. 3, 4 Developing this infrastructure and model for vaccination delivery will allow for orderly distribution of the product which must be linked to efficient billing process through multiple channels to create a much needed active surveillance system. Vaccine administration has been at the forefront of innovative public health delivery. Part of this innovation has led to the development of organized record keeping systems to document the administration. In 1955, Congress passed the Polio Vaccination Assistance Act at the time private physicians were urged by the American Medical Association to make records on vaccinations they performed consisting of the name and age of the individual, the site of injection, and source and lot number of the vaccine. 5 In 1962, Congress extended the Centers for Disease Control and Prevention's (CDC) Public Health Service Section 317 Immunization Grants Program to establish the Vaccination Assistance Act to assist in purchasing vaccine doses. In addition to direct public vaccine provision, the act developed immunization registries and promoted the conduct of vaccine-preventable disease surveillance and population needs assessments. 6 In 1986, the National Childhood Vaccine Injury Act was enacted and afforded the The FDA Sentinel System is a distributed data network with a common data model (CDM) of curated real-world data and distributed analytic tools to generate real-world evidence for FDA decisionmaking, 8 and offers a unique ability to conduct active medical product surveillance as has been shown before for influenza. 9 However, the Sentinel System lacks the electronic documentation of community and workplace vaccine administrations and is delayed in physician and health system medical record claims documentation of vaccine administration. In order to maximize the utility of such surveillance systems, administrations of a COVID-19 vaccine should be broadly available with an ability to integrate data into a CDM such as Sentinel. One way to facilitate broad availability is to consider use of pharmacy distribution systems given the robust ability of pharmacy claims adjudication to provision a near real-time registry. There are three reasons distribution and physical administration should be conducted through retail pharmacies or utilize the retail pharmacy distribution and adjudication systems. (1) Controlled distribution of product through existing supply chain processes; (2) Established electronic claims adjudication conducted at the time of physical administration; (3) Reduced burden on health systems and providers who will be providing care for those with COVID-19. Health systems that wish to administer the vaccine to either hospital or home bound patients could utilize retail pharmacies owned by those health systems or local pharmacy distribution for documentation. While the current infrastructure in place serves as an excellent foundation, community pharmacies will need additional nursing and public health staff trained in immunization delivery to aid in increased physical administrations. In addition, local pharmacies will need to be staffed with additional pharmacy technicians to process the electronic documentation of vaccine administrations. This process can be modeled after the seasonal influenza vaccine programs most retail pharmacies provide with documented ability to increase vaccine distribution reach and capacity. 10 Through secure smart phone technology, pharmacy claims adjudication using bar code scanning via secure pharmacy claims processing could be established virtually anywhere, including physician offices, hospital entrances, airports, places of worship, community centers, or mobile clinics. Smart phone technology has been used in Syria to document vaccine administrations. 11 Similarly, the Handheld Automated Notification for Drugs and Immunizations (HANDI) system has captured influenza vaccination data during Denver Health's annual employee influenza campaign. 12 Engaging state boards of pharmacy to permit this mobilization of the pharmacy distribution network would help expand the availability to all corners of health care delivery and community engagement while maintaining the ability to create the digital registry. The utilization of administrative pharmacy claims to conduct high quality comparative effectiveness vaccine studies of influenza vaccine have shown the utility of this real world data to support evidence generation. 13 Physician billing processes through procedure claims documentation of HCPHCs and CPT codes is slow and prevents real time utilization in safety surveillance systems a radical shift would be to have providers bill through NDC pharmacy claims systems for more real time electronic data capture. The rapid adjudication of pharmacy claims within the FDA Sentinel System has been proven to provide an active product surveillance framework for vaccine safety. 14 The traditional pharmacy transactional claims processing can provide a robust mechanism to electronically update a registry of the population vaccinated and through technology enabled solutions provide this registry securely to providers to update patient's electronic health records (EHR). This integration of retail pharmacy data with EHRs would greatly enhance the immunization information systems (IIS) developed at the state level to track immunization histories as many are in desperate need for modernization. 15 A patchwork of state laws limits the utility of these vital information systems in how the data are collected and transmitted. 16 Coordinator and the CDC, it is feasible now to put in place the mechanisms to improve vaccine safety surveillance. 18 Although given the public health reporting purpose, which allows for direct use of personally identifiable information (PII), secure privacy preserving record linkage could be implemented to further protect PII in a Health Insurance Portability and Accountability Act As our nation contends with the current COVID-19, we must also prepare the vigilance systems necessary to digitally track the physical administration of a future available vaccine and ensure that public safety surveillance monitoring will be in place to protect public health. Our nation has an opportunity to build the necessary digital infrastructure to support the public health safety surveillance to counter emerging threats. World Health Organization.
