Nature has published a large study showing that text message reminders to receive a COVID-19 booster worked to increase vaccine uptake, but that offering free rides to pharmacies did not.
Several variants are likely to be contributing to the nationwide trend, said Dr. Dan Barouch, director of the Center for Virology and Vaccine Research at Beth Israel Deaconess Medical Center in Boston.
The authors compared outcomes among those who had received an updated XBB vaccine and those who had not received an XBB vaccine of any kind, regardless of prior COVID-19 vaccination or infection history.
