Covid-19
Research shows COVID-19 vaccination does not increase the risk of delivering a baby who weighs less than usual for the number of weeks of pregnancy.

COVID-19 vaccination during pregnancy was not associated with preterm delivery or underweight newborns, a fresh survey by the US Centers for Disease Control and Prevention (CDC) shows.

The rates of preterm birth were 4.9 percent among more than 10,000 women who received at least a shot of COVID-19 vaccine, compared to 7 percent for roughly 36,000 unvaccinated women.

The research also found out that COVID-19 vaccination did not increase the risk of delivering a baby who weighed less than usual for the number of weeks of pregnancy, therefore supporting the CDC’s recommendation on the safety of the jab during pregnancy.

“Evidence of the benefits of COVID-19 vaccination during pregnancy continues to accrue, including the detection of antibodies in cord blood,” the researchers wrote, noting that pregnant women with COVID-19 have increased risks for intensive care unit admission, need for mechanical ventilation, and death.

The women in the study had become pregnant between May and October of 2020, well before the vaccines were available.

Nearly all who were vaccinated got the shots in their second or third trimester of pregnancy.

Some 96 percent of them had received at least one dose of an mRNA vaccine from either Pfizer Inc and BioNTech, or Moderna Inc.

The other group of participating women received the single-shot vaccine from Johnson & Johnson.

There were no differences in the outcomes based on the timing of vaccination, or on which mRNA vaccine was received, or how many doses.

The data were drawn from eight healthcare organizations in six US states, the report said.

However, the researchers noted that because they reviewed data collected for other purposes, they may have missed some vaccinations, and they lacked information on women’s previous history of birth-related complications.

The survey also lacked information on first-trimester vaccinations and on boosters, which were not available at the time.
