About Vaccine Track
GSK and IQVIA has launched Vaccine Track, the first comprehensive, public data tool for understanding adult vaccination trends in the United States, with an aim to provide an open data resource for immunization partners and decision makers to convene around shared public health goals to recover and improve uptake of recommended vaccines.
GSK is a science-led global healthcare company. For further information please visit www.gsk.com/about-us.

IQVIA claims data are sourced from vaccinations administered in physician medical offices and retail pharmacies (including chain, mass merchandise, food stores, and independent pharmacies). Vaccines administered in the workplace, community (e.g., Federally Qualified Health Centers (“FQHCs”)), institutional, or hospital settings are not included in these data.
All claims and data sources are run through a patented encryption engine to create a de-identified patient token which protects patient privacy. The end result is Health Insurance Portability Accountability Act (“HIPAA”) compliant anonymized patient- level data that can be linked longitudinally across data sets.
Medical claims are projected (e.g., using a sample to estimate the full population) nationally to the American Medical Association (“AMA”) universe of office-based physicians. Due to potential sample bias, all reporting sub-nationally leverages raw medical claims. Sub-national reporting represents the state of the rendering provider.
Pharmacy claims are collected from reporting, or “sample”, pharmacies and projected nationally and sub-nationally to IQVIA’s syndicated universe of retail pharmacy prescriptions. Non-sample pharmacy volume is accounted for in the syndicated universe by applying several statistical analyses based on volume from sample pharmacies. Occasionally, manufacturers will prohibit, or “block”, their products data from being shared with third parties. Blocked products are not accounted for in syndicated or custom reporting. Sub-national reporting represents the state of the pharmacy where the vaccine was administered.
Race/ethnicity data was not available for all patients that received a vaccination. These data are thus not representative of the entire U.S. population.
Medical Claims Data
Medical claims include anonymized patient level data containing diagnosis, procedures, and treatments received during visits to U.S. office-based professionals. Medical claims data is sourced from 837p claims and collected through practice management software vendors and switch clearinghouses. IQVIA captures claims from 82% of AMA physicians, however, actual sample collected can vary greatly depending on therapeutic area and products.
Longitudinal Prescription Data
Longitudinal prescription claims include anonymized patient level data that capture what therapy a patient starts on and how it changes over time. The majority of longitudinal prescription information is collected directly from pharmacies, but data is also collected from Switches and software vendors and IQVIA coverage is ~92% across retail pharmacies.
Consumer data allows for the understanding of the patient beyond age and gender to create stronger patient insights. IQVIA can report on 2,000 attributes, such as race/ethnicity, by matching the de-identified consumer to its Medical and Longitudinal Prescription data assets. Consumer match rates to claims data can vary greatly depending on therapeutic area and geographical composition. Reported attributes should be considered directional as they are not representative of the entire U.S. population.
