[Serum interferon in newborn infants and their mothers]

The results from a study on serum interferon in newborns and their mothers are described. The newborns infants receive serum interferon transplacentally in a relative part of the examined cases. Coincidence in the levels of interferon in newborns and their mothers is found in 50% of the cases. Intrauterine synthesized interferon (5.8%) with considerable concentration is also established, due probably to ascendant virus infection.
