[Determination of effectiveness of FMD vaccine type Asia 1 in neutralization tests in cattle].
On June 20th 1984 FMD type ASIA 1 appeared in two herds of cattle for the first time in Europe (Greece). All affected and suspected cattle (1200) were killed on July 4th to 13th 1984. Blood samples of 125 of these animals were collected and examined by neutralisation test. All susceptible animals in this area as well as of buffer zone were vaccinated against ASIA 1 (from FAO, produced by IFFA Merieux). In three weeks after this first vaccination blood samples from 148 animals were collected, examined and the results of the neutralisation test were correlated with the effectiveness of the vaccine. 17.2% from these animals have been found to have neutralisation titers less than 1.2.
