In this worked example the dilution that provided the 50 percent infection of eggs or 1 EID 50 is 10-8.7. The reciprocal of this dilution is the amount virus contained in the 0.1 mL of the original suspension = 10 8.7 EID 50 /0.1 mL = 10 9.7 EID 50 /mL. The infectivity titre of I-2 wet vaccine stored at 4°C has been calculated to be 10 9.7 EID 50 /mL.
