COVID-19 Vaccination During Pregnancy Offers Protection to Infants

Strategic Insights -

Getting vaccinated against COVID-19 during pregnancy could provide some protection to babies after they're born, according to a new study published by the US Centers for Disease Control and Prevention. The study found that infants born to mothers who received two doses of either the Moderna or Pfizer/BioNTech vaccines during pregnancy had a reduced risk of being hospitalized with COVID-19 in the first six months of their lives. This protection is significant, especially in the context of recent increases in hospitalizations among very young children.

Key Takeaways:

  • The study suggests that maternal vaccination is an effective way to protect young infants from COVID-19, with a 61% reduction in hospitalization risk.
  • Infants whose mothers received the vaccine during the second half of pregnancy had an 80% effectiveness in preventing hospitalization due to COVID-19.
  • The study found that 88% of infants born to mothers not vaccinated before or during pregnancy were admitted to the ICU with COVID-19.
  • The researchers believe that COVID-19 antibodies can be transferred from the mother to the baby across the placenta, providing protection to the infant.
  • The study highlights the importance of maternal vaccination in protecting infants from severe illness, particularly during their first six months of life.

Statistics:

  • 61% reduction in hospitalization risk among infants born to mothers who received the COVID-19 vaccine during pregnancy.
  • 80% effectiveness in preventing hospitalization due to COVID-19 among infants born to mothers who received the vaccine during the second half of pregnancy.
  • 15.9% of mothers of infants with COVID-19 were vaccinated during pregnancy, compared to 32% of mothers of infants without COVID-19.
  • 10.3% of mothers of infants with COVID-19 were vaccinated early during pregnancy, and 5.7% were vaccinated late in pregnancy.
  • 49.9% of infants with COVID-19 had mothers who were vaccinated, compared to 67.5% of infants without COVID-19.
