| comparison of antibodies against different viruses in cerebrospinal fluid and serum samples from patients with multiple sclerosis. | the occurrence of a local production in the central nervous system (cns) of antibodies against different selected viruses was analyzed by comparison of titers in serum and cerebrospinal fluid samples from groups of 50 patients with multiple sclerosis from finland, norway, and sweden. measles antibodies were determined in hemagglutination inhibition, hemolysis inhibition, and nucleocapsid complement fixation tests; mumps, parainfluenza virus type 1, and rubella virus antibodies were determined in ... | 1974 | 4372178 |
| measles antibodies and herd immunity in 20- and 40-year-old norwegians. | the introduction of a measles vaccination programme in norway in 1969 using one dose of vaccine, and since 1983 two doses, was followed by a substantial decrease in the incidence of the disease. since 1992, the annual incidence has been less than 20 cases. small clusters and outbreaks have occasionally been observed among military personnel and unvaccinated children. this paper describes a seroepidemiological investigation of the level of immunity among 1,188 military conscripts, aged 18-28 year ... | 1997 | 9181648 |
