Type 2 shedding in children and infants after monovalent OPV2 and high-dose novel OPV2 administration

Proportions (with 95% CI) of children (A) and infants (B) shedding poliovirus type 2 (PCR-positive stools) 7, 14, 21, and 28 days after vaccination with monovalent OPV2 or high-dose novel OPV2 candidates. Shedding was compared with the two-sided Fisher's exact test. p values indicated when novel OPV2 data were significantly different versus monovalent OPV2. OPV2=type 2 oral poliovirus vaccine.
