Researchers Find Link Between COVID Vaccine Hesitancy and Risk of Traffic Crashes
Awareness of these risks might help to encourage more COVID vaccination
Coronavirus disease (COVID-19) vaccine hesitancy is a reflection of psychology that might also contribute to traffic safety. We tested whether COVID vaccination was associated with the risks of a traffic crash.
We conducted a population-based longitudinal cohort analysis of adults and determined COVID vaccination status through linkages to individual electronic medical records. Traffic crashes requiring emergency medical care were subsequently identified by multicenter outcome ascertainment of all hospitals in the region over a 1-month follow-up interval (178 separate centers).
A total of 11,270,763 individuals were included, of whom 16 percent had not received a COVID vaccine and 84 percent had received a COVID vaccine. The cohort accounted for 6682 traffic crashes during follow-up. Unvaccinated individuals accounted for 1682 traffic crashes (25 percent), equal to a 72 percent increased relative risk compared with those vaccinated (95 percent confidence interval, 63-82; P < 0.001). The increased traffic risks among unvaccinated individuals extended to diverse subgroups, was similar to the relative risk associated with sleep apnea, and was equal to a 48 percent increase after adjustment for age, sex, home location, socioeconomic status and medical diagnoses (95 percent confidence interval, 40-57; P < 0.001). The increased risks extended across the spectrum of crash severity, appeared similar for Pfizer, Moderna or other vaccines, and were validated in supplementary analyses of crossover cases, propensity scores, and additional controls.
These data suggest that COVID vaccine hesitancy is associated with significant increased risks of a traffic crash. An awareness of these risks might help to encourage more COVID vaccination.
