It was concluded that the sera are suitable for the purpose, and they are accordingly established as International Standards for Anti-Poliovirus Sera, Types 1, 2 and 3, replacing the existing International Reference Preparations for the same sera, established in 1958. The unitage was defined as follows: For Type 1 preparation: 1 unit is 10.78 mg. For Type 2 preparation: 1 unit is 10.46 mg. For Type 3 preparation: 1 unit is 10.48 mg.
