Open Source Solutions for Immunization Tracking and COVID-19

The United States is starting to emerge from a nation-wide shut down imposed to slow down the spread of COVID-19. Most states are starting to reopen, and while higher education will likely stay largely remote this fall, primary and secondary schools are expected to reopen as the economy tries to get back on its feet. As both children and adults begin to spend more time together again, it is important to understand the impact that COVID-19 is having on current immunization practices and services, and how open source software is being leveraged to keep the population safe.

Data Management for Large-scale COVID-19 Immunization: This is all not as simple as it seems

There is a global race for the development of a vaccine for the SARS-CoV-2 virus that causes COVID-19. Finding a vaccine that works and receives approval is only part of the process. There are a series of other steps that need to be taken so that the vaccine can be delivered. These include the mass production of the vaccine, shipment, administration and record-keeping.

Feature Overlaps Between Immunization Information Systems and EHRs

Immunization Information Systems (IIS) have been around for nearly twenty years. Their functionality, completeness, and usefulness have all increased over this time. IIS and electronic health record (EHR) systems have always had unique features, as well as some overlapping features, and the deployment of EHRs has enhanced the local immunization capabilities of clinician practices. Several critical clinical features that are considered to be core functions of IIS are beginning to be supported by EHRs. This article will review and discuss five such critical features: online data entry, clinical decision support for immunization, reminder-recall, practice-level assessment of up-to-date status, and patient access to their immunization data.
