Forty-six infants, ranging from less than 1 day to 6 months of age, were given more than 100 feedings of living, attenuated poliomyelitis viruses without the occurrence of major or minor illness. The strains used were CHAT (type 1), Wistar (type 1), Jackson (type 2), P-712 (type 2) and Fox (type 3). All strains except the Jackson strain were found to be antigenic on oral administration. Response to vaccination was demonstrated in these infants by the presence after vaccination of antibody levels significantly in excess of those attributable to transplacentally acquired antibodies, and by the detection of fecal excretion of poliomyelitis virus. Infants less than 2 months old were more difficult to immunize than older infants. The evidence suggests that biologic immaturity rather than transplacental antibodies caused the difference. When the three types of poliomyelitis virus were fed at 3-week intervals, responses occurred to all types. No interference between types was observed when they were fed in all possible sequences. Three infants given a second feeding of homotypic, attenuated poliomyelitis virus 3 to 5 months after a successful vaccination showed resistance to intestinal reinfection.

Approximation Errors

We give the estimates of approximation errors while approximating of a positive operator $A$ in a Banach space by analytic vectors. Our main results are formulated in the form of Bernstein and Jackson type inequalities with explicitly calculated constants. We consider the classes of invariant subspaces ${\mathcal E}_{q,p}^{\nu,\alpha}(A)$ of analytic vectors of $A$ and the special scale of approximation spaces $\mathcal {B}_{q,p,\tau}^{s,\alpha}(A)$ associated with the complex degrees of positive operator. The approximation spaces are determined by $E$-functional, that plays a similar role as the module of smoothness. We show that the approximation spaces can be considered as interpolation spaces generated by $K$-method of real interpolation. The constants in the Bernstein and Jackson type inequalities are expressed using the normalization factor.
