If a pregnant mother receives the H1N1 vaccine, will the baby have some immunity to the H1N1 virus after it is born?
After vaccination with seasonal flu vaccine, there may be passive transfer of anti-influenza antibodies that might provide some protection from the vaccinated woman to the newborn. At this time, there is no specific data available for H1N1 vaccine and passive transfer of antibodies from vaccination of pregnant women to their newborns.
