A seroprevalence study of poliovirus antibody against a collection of recombinant and non-recombinant poliovirus vaccine strains in the population of southern Greece.

In this study, the serological status of the southern Greek population in the 1­10-year, 11­20-year, 21­30-year and 31­40-year age groups with regard to Sabin vaccine strains and a collection of 15 recombinant and four non-recombinant poliovirus vaccine strains was determined. For all three poliovirus types, the highest neutralization test (NT) titres were observed in the 1­10- year age group, indicating a good response to vaccination. In general, the serological status of the population of southern Greece with regard to poliovirus is better for types 1 and 2 than for type 3. The presence of the lowest NT titre in the 21­ 30-year age group against poliovirus type 3 suggests the need for a booster dose of monovalent Sabin3 vaccine to ensure personal and herd immunity.
