A nation-wide campaign with trivalent oral poliovirus vaccine was organized in Finland in February-March 1985 in order to stop the unexpected outbreak of poliomyelitis. Excretion time of the vaccine viruses and antibody responses due to vaccination were studied in a group of healthy 6-year-old child

Abstract
HIV excretion patterns and specific antibody responses were evaluated in blood, semen, female genital secretions, saliva, and crevicular fluid. Samples were examined for infectious virus, viral antigens, viral nucleic acid, HIV specific IgG, IgA, antiβnef, and antiβp24. Viral load in peripheral blood appeared to increase with disease progression. The proportion of patients with antibody responses specific for nef and p24 was also lower among patients with more advanced disease. Infectious virus and viral antigens were detected infrequently and at lower levels in body fluids than in blood, which may reflect the presence of local antibodies. HIV nucleic acid was detected in some semen and saliva samples in the absence of infectious virus.
