Serological studies of the immunological condition versus rebulla virus in maternal and neonatal serum samples

In 116 serum pairs sampled from the mother and the newborn at delivery, the antibody level against Rubeola virus has been assessed haemagglutination inhibition test. Thirty one per cent of the mothers resulted not protected, as the antibody titer was below 1/16. A situation akin to that described in the same percentage of not protected women was 29,45%. In 19% of the newborns the antibody level against the virus proved higher than the mother's one by at least two dilution factors. Research work is in progress to try the reason of this result, as a possible consequence of different Ig classes or aspecific inhibitors involved.
