Caution is advised when interpreting the immunization records of Russian immigrants.
We advise you to disregard any history of rubella immunization when the immunization was given prior to the person's arrival in this country. Please give a MMR vaccination to Russian immigrant children upon arrival in the U.S. if the child is over one year of age, and administer a second dose at sixth grade entry. It is wise to revaccinate any child who has immigrated from a developing country with MMR vaccine. The exclusion period may be extended if additional cases occur. All susceptibles are being offered MMR vaccination.
