From the Editor:
Studies including ours showed that air pollution exposure was associated with increased risks of coronavirus disease (COVID-19) incidence and severity, including COVID-19–related hospitalizations (1–4). Most studies were conducted during the early pandemic when COVID-19 vaccination was not administered widely. Few studies have been conducted after the vaccination campaign (5, 6). It is unknown how COVID-19 vaccination affects the adverse effects of air pollution exposure. This research letter reports findings assessing associations of long- and short-term exposures to three ambient air pollutants: nitrogen dioxide (NO2), fine particles (PM2.5), and ozone (O3) with COVID-19–related hospitalizations during July and August of 2021 when the Delta variant was the dominant strain, COVID-19 vaccines had been distributed over 7 months, and booster vaccines had not yet started (7); and effect modification with COVID-19 vaccination.
