Table 5. One way antigenic relationship (r1-value) of the outbreak and carrier virus isolates with the currently used vaccine strain, O/IND/R2/1975, as determined by 2D-VNT assay.
Values are expressed as mean± standard deviation (s.d). Values <0.3 are in bold, indicating poor vaccine protection against that isolate.
