Abstract: | A follow-up study of poliomyelitis, rubella, and dengue antibodies has been made in light of results obtained in a 1972 health and serological survey in Barbados, W.I. Poliomyelitis antibody neutralization tests performed on sera from 307 children under age 15 using overnight serum/virus mixtures on microtiter plates at low serum dilutions revealed the absence of polio antibody at 1:2 dilution in 13.7% for type 1, 6.5% for type 2, and 14.3% for type 3 virus. A significant correlation of the presence or absence of poliomyelitis antibody to types 2 and 3 was seen with the response to immunization histories. Forty-three of 49 girls (88%) given rubella vaccine (RA 27/3) in 1972 had demonstrable haemagglutination-inhibition antibody 4 years later. Neutralization tests for dengue antibody confirmed the results of the complement-fixation tests and indicated that type 2 was probably the sole infecting strain. |
