Key result
Among 411 sera samples from São Paulo, Brazil, protective neutralizing antibody titers (≥1:8) were present in 88.1%, 88.8%, and 61.6% for poliovirus serotypes 1, 2, and 3, respectively.
Cross-Sectional (n=411)
Evaluation of poliovirus immune status shows high seroprevalence for serotypes 1 and 2, but lower for serotype 3, which may inform polio vaccine policy.

Highlights potential type 3 immunity gaps in São Paulo; leaves open need for targeted surveillance or boosters.
Luchs et al. (2010) conducted a cross-sectional in Poliovirus immune status (n=411). Poliovirus neutralizing antibodies was evaluated on Presence of neutralizing antibody titres ≥1:8 for poliovirus serotypes 1, 2, and 3. Among 411 sera samples from São Paulo, Brazil, protective neutralizing antibody titers (≥1:8) were present in 88.1%, 88.8%, and 61.6% for poliovirus serotypes 1, 2, and 3, respectively.
