Respiratory Syncytial Virus (RSV) Adult Vaccinations Administered

Respiratory Syncytial Virus (RSV) Vaccinations Administered in Retail Pharmacies and Physicians’ Medical Offices*, Adults 60 years and older, United States

The projected pharmacy estimates are based on IQVIA^†,‡ LRx product and vaccinations administered in retail pharmacies (including chain, mass merchandise, food stores, and independent pharmacies). Using the raw number of doses administered at a sample of retail pharmacies, IQVIA uses a proprietary projection methodology to estimate the projected number of vaccinations administered at all retail pharmacies For the 2023-24 season, projected estimates are based on a sample of 40,469 pharmacies.^{^} The estimates include RSV vaccinations that were billed to insurers (i.e. claims) or paid by cash. Projected pharmacy estimates are updated each week for the prior 13 weeks. Evaluations are underway to determine average time-lag for claims and data processing for RSV vaccinations; for comparison purposes, initial evaluation of IQVIA flu vaccination estimates is available and indicates that the reported number of doses administered for a particular week increased over the next few weeks.
The projected physicians’ medical offices estimates are based on IQVIA’s Dx product. Using the raw number of doses administered at the offices of a sample of physicians from American Medical Association’s (AMA) proprietary list, IQVIA uses a proprietary projection methodology to estimate the projected number of vaccinations administered in medical offices of all physicians from AMA’s list. For the 2023-24 season, projected estimates were based on a sample of 2,866 AMA physicians. The number of AMA primary care physicians in the U.S. is 258,350.^± The estimates include RSV vaccinations that are claims-based only, and estimates are expected to increase over time for a given time period as claims are processed and adjudicated. Projected estimates are updated monthly and do not mature until about two months. This results in an increase or decrease in the initial or subsequent estimates for a given week. Evaluations are underway to determine average time-lag for claims and data processing for RSV vaccinations; for comparison purposes, initial evaluation of IQVIA flu vaccination estimates is available and indicates that the reported number of doses administered for a particular week increased over the next few weeks.
Vaccinations administered in workplaces, community locations, long-term care settings, and other medical settings such as public health clinics are not represented in these data.
