Norway Study: COVID Vaccine in Pregnancy Halves Newborn Hospital Risk

Pregnant women in Martin, St. Lucie, and Indian River counties have new research backing a vaccination choice their own doctors have long recommended: a large study confirms that receiving a COVID-19 vaccine during pregnancy meaningfully shields newborns from the virus during their most vulnerable early months.

The study, published Friday in the journal Pediatrics, tracked 146,031 children born in Norway between March 2020 and December 2023, following their medical records for up to two years after birth. Infants whose mothers were vaccinated during pregnancy were about half as likely to be hospitalized specifically for COVID-19 in their first two months of life, according to lead author Dr. Helena Niemi Eide and colleagues. By three to five months of age, that protection remained, reducing the risk of a COVID-related hospital visit by 24 percent. The protective effect faded after the six-month mark — precisely when infants become eligible to receive their own COVID vaccine. That research finding directly supports the guidance the American College of Obstetricians and Gynecologists (ACOG) has issued for providers, who counsel expectant mothers on vaccination throughout pregnancy.

The study also addressed a claim circulating in federal vaccine policy circles that COVID vaccination could cause "immune dysregulation," a disruption of the body's infection-fighting response, and leave children more susceptible to other illnesses. Researchers found no increased risk of overall infections in babies whose mothers were vaccinated, contradicting that assertion.

Babies under six months old face COVID hospitalization rates comparable to adults ages 65 to 74, according to a separate September 2024 study. Roughly one in five of those infants required intensive care. Yet no COVID vaccine is currently authorized for children younger than six months, making maternal vaccination during pregnancy one of the few available tools for protecting newborns.

The Norwegian study was funded by the University of Oslo and a Scandinavian government agency, with no pharmaceutical industry funding. ACOG reaffirmed its recommendation that pregnant patients receive the COVID vaccine in the same week the research was released.
