The apparent adverse impact of COVID on preterm births diminished quickly in places where vaccines were widely accepted. Based on these observations, the authors state that vaccination prevented a large number of preterm births during the pandemic. A study by Northwestern University Chicago found no rise in preterm births during the pandemic, and oddly, a decrease in preterm deaths among low-income groups. in Orissa found a higher frequency of preterm births among unvaccinated women compared to vaccinated. There could well be additional unmeasured variables, perhaps socio-economic in nature that explain the observed difference in preterm births between highly vaccinated areas and less vaccinated areas.
