RIWI’s RDIT Tracks Vaccination Rates in Real Time in the U.S.

RIWI’s Random Domain Intercept Technology (RDIT) was recently leveraged in a study to gauge and measure vaccination rates across the United States. RDIT, in such circumstances is the ideal solution to an issue faced by governments and societies alike to collect timely and accurate data. The objective of the study was to assess the validity of RDIT for tracking self-reported vaccination rates in real time at the US national and state levels. RIWI used RDIT from June 30 to July 26, 2021, to reach a broad sample of US adults (18 years+) web users and asked questions related to COVID-19 vaccination. Self-reported vaccination status was used as the focus of this validation exercise.

By using RDIT, 63,853 adult web users reported their vaccination status (6.2% of the entire American web-using population that was exposed to the survey). At the national level, the RDIT-based estimate of adult COVID-19 vaccine coverage was slightly higher than the CDC-reported estimate (67.9%) on July 15, 2021 (midway through data collection). However, the RDIT-based and CDC-reported state-level estimates were strongly correlated.

RIWI’s unique technology allows for this broad-reaching, real-time data stream to provide advantages for tracking the use of a range of vaccines and for the timely evaluation of vaccination interventions. Moreover, RDIT could be harnessed to rapidly assess demographic, attitudinal, and behavioral constructs that are not available in administrative data, which could allow for deeper insights into the real-time predictors of vaccine uptake–enabling targeted and timely interventions.
