The three Sabin strains of poliomyelitis seed virus were serially passaged in either secondary monkey kidney or Vero cell cultures and the tenth passage of each virus harvest compared to non‐passaged Sabin reference virus of the same type using the monkey neurovirulence test. All three types were further attenuated by passage in Vero cells, whereas only type 2 became further attenuated after passage in secondary monkey kidney cells. After passage in Vero cells, type 3 poliomyelitis virus became more heat stable, as measured by its replicative capacity at 40°C.
