[Effect of a live measles vaccine on the chromosome apparatus of mouse bone marrow cells].

Vaccination of albino mice with live measles vaccine caused an increase in the chromosome aberrations frequency during the period from the 30th till the 120th day of the experiment. The maximum increase in the number of chromosome aberrations as well as in centromeric and telomeric chromosome associations was observed 60 days after immunization. Chromatid breaks were main type of the structural aberrations observed.
