How a mother's antibodies affect newborn flu vaccine protection

The interplay of maternal antibody and newborn vaccine responses

NIH-funded research Wake Forest University Health Sciences · NIH-11322702

What this research studies

If you are pregnant or have a newborn, this work studies how the antibodies you pass to your baby before birth affect the baby's response to flu vaccines. Researchers will measure antibody levels transferred across the placenta and follow how those maternal antibodies change the infant's immune reactions after vaccination. They will use models that closely mimic human maternal antibody transfer and examine immune responses over time to find vaccination timing or methods that let babies build their own protection as maternal antibody fades. The overall aim is to reduce the vulnerable window when very young infants are at high risk for severe flu.

Who could benefit from this research

Good fit: Ideal candidates would be pregnant people and their newborns, particularly infants under six months of age whose protection depends on antibodies received from the mother.

Not a fit: Older children, adults, or infants beyond the early vulnerability window who are already eligible for standard vaccination would not be the focus and are unlikely to benefit directly from this newborn-focused work.

Why it matters

Potential benefit: If successful, this could lead to vaccine timing or approaches that help infants develop lasting protection against influenza even when they start life with maternal antibodies.

How similar studies have performed: Previous work shows maternal antibodies can both protect infants and sometimes interfere with infant vaccine responses, and strategies to overcome that interference have shown mixed but promising results.
