The WI/DHS-Immunization Program developed the Wisconsin Immunization Registry (WIR), an online database that tracks vaccine records for Wisconsin children and adults (WIR, 2019). The WIR was used to verify the immunization status for children and youth whose caregivers were enrolled in CHIMC. Enrolled participants and CHIMC partners received training on how to use the WIR.

There are limitations in this study. First, due to the prospective time-series data, our study was limited by a lack of detailed records on potential confounders, although the model is effective and reliable which corresponds to previous approaches[13,15]. Therefore, enough data should be collected and analyzed with the development of disease surveillance. Second, we could not illustrate the associations between one-dose and two-dose clearly, thus, potential exposure misclassification may have occurred. Third, Possible surveillance bias might have impacts on the study results, because varicella was defined through clinical diagnoses or laboratory confirmation. However, physicians in one city usually have integrative stability level of diagnosis technology, and the occurrence of varicella cases in our study varied slightly over the long term. Finally, breakthrough varicella cases with milder symptoms may be less likely to seek medical consultation or require hospital admission. In addition, vaccination coverage presented in the immunization registry may be overestimated, since unvaccinated children may be underrepresented [23]. We obtained only reported five-year data, which was not sufficient to develop an understanding of long-term effects. Therefore, more data should be collected and analyzed in the future.
Records request response rate and vaccination status of first-time college students at a mid-sized Midwestern university

The SHC’s Immunization History Form (IHF) was a five-page document with fill-in-the-blank boxes. Identifying information requested at the top included the student’s name, address, phone number, birth date, and sex. The subsequent boxes requested vaccination dates for Tetanus and Diphtheria (Td) or Tdap, MMR, varicella, hepatitis A, HepB, menACWY, meningitis B, influenza, Diphtheria, pertussis, and tetanus (DPaT), polio, and HPV. For varicella, a history of disease was also considered acceptable. It was also common that students returned a copy of their state immunization registry record. The most common document returned was from the Wisconsin Immunization Registry (WIR). This document usually included basic identifying information such as name, birth date, and mother’s maiden name. It listed vaccines obtained along with the date of each dose. The WIR has been shown to be an accurate source of immunization history data.21 Finally, some students returned personal medical records. Many were printed from the medical records maintained by the students’ primary care providers (PCP). The formatting of these records varied, though many were in a list form by either date of vaccination or by vaccination type.

Generally, impact studies utilized vaccination coverage data at the national level, whereas vaccine effectiveness studies (38, 39.6%) often relied on self-reported vaccination status (Table 2). In one-third of the studies reviewed, self-reported vaccination status was verified in a proportion of the participants using claim databases (7/38, 18%) or EHR (6/38, 16%). Registries were also a frequently used source of data to ascertain HPV vaccination status (45/196, 23%). In general, these registries pre-dated the HPV vaccine and are used for all (childhood) vaccinations and all or a selection of adolescent and adult-age vaccinations. As an example, the Danish Vaccination Register covers all vaccinations, including those given outside the National Immunization Program. Registration is in real-time and data retrieval and linkage can be performed for surveillance or research [175]. In Australia, a national HPV vaccination registry was implemented at the time of the roll-out of the immunization program. Recently, this registry has been included into the Australian Immunization Registry.
