UW professor behind study showing COVID-19 vaccines reduced premature births breaks down findings

COVID-19 caused an alarming surge in premature births, says Jenna Nobles, a UW sociology professor. “The effect of maternal COVID infection from the onset of the pandemic into 2023 is large, increasing the risk of preterm births over that time by 1.2 percentage points,” Nobles said. “To move the needle on preterm birth that much is akin to a disastrous environmental exposure, like weeks of breathing intense wildfire smoke.”
