I have written previously about the role that Immunization Information Systems (IIS) play in the US with respect to providing authoritative, complete information about vaccinations for the citizens within their jurisdictions. Under Centers for Disease Control and Prevention (CDC) leadership, the IIS community is making strides towards enabling a more transparent exchange of information between IIS. This is to primarily ensure that vaccinations received by an individual in a location other than where they live (for example, a workplace or school in another state) will find their way to the IIS in the individual’s home jurisdiction. This ensures that the IIS where a person lives has as complete a record as possible.
I have been writing for some time on the topic of vaccine credentials in the US and especially the role of public health registries in creating and supporting them. While the rules around data management for vaccinations apply within the US, people move in and out of the country and their data needs to move with them. Managing and documenting vaccination events for people inside the US who received COVID-19 vaccinations outside of the US is challenging and may not get easier anytime soon.
I have been monitoring the vaccine credential effort for a long time and watching various initiatives worldwide with a particular focus on what might be done in the United States. In a series of blog posts over the past several months I have described at length how the situation in the US differs from the situation in many other countries. In this post I will review the “facts on the ground” as I see them and offer a way forward for the US.
More than a year into the COVID-19 outbreak and the lockdowns to slow the spread of the virus, one of the key factors to reopen the United States and some other countries may be a requirement for individuals to prove that they have been vaccinated against COVID-19. This “Proof” of vaccination is called vaccine credentialing and will likely be embodied in a paper or electronic certificate. We have discussed this extensively in a series of articles (see below). On the other hand there are already systems of records that have a far more extensive vaccination history. There is a major concern here among public health officials that the push to minimalization with vaccine credentials will push aside fuller vaccination history. As part of their core function, Immunization Information Systems (IIS) already provide complete and comprehensive immunization records for the individuals whose records they hold either directly or through a clinical provider. In this article we will address the similarities and differences between vaccine credentials and traditional immunization histories and offer some opportunities for public health to maintain its role in data access.
US public health agencies have been playing a critical role in the response to the COVID-19 pandemic. They are currently managing an unprecedented vaccination campaign. Immunization Information Systems (IIS) are a key tool that these agencies use to manage their public health mission and the vaccination campaign. How should public health agencies understand and manage the flurry of controversy – and the loud cautions – surrounding digital vaccine credentials? This blog post is part of a series of posts we have written over the past few weeks where we offer specific advice to reduce confusion about what vaccine credentialing is and how it functions. As a leading public health informatics consulting company, HLN is uniquely positioned to provide guidance and support for government, private enterprise, and consumers interfacing with IIS projects and their standards.
