title: Efficacy study of a new albumin-free human diploid cell rabies vaccine (Lyssavac-HDC, Berna) in 100 severely rabies-exposed Thai patients.
abstract: A newly developed human diploid cell rabies vaccine (Lyssavac-HDC), produced without added serum albumin and with an effort to remove the virus-inactivating beta-propriolactone prior to addition of the gelatin, L-cysteine and potassium phosphate stabilizer, was tested for safety immunogenicity, adverse reactions and efficacy in 100 severely rabies-exposed Thais. All patients also received human rabies immune globulin and vaccine was administered using the conventional 5-dose intramuscular schedule of one dose on days 0, 3, 7, 14 and 28. One hundred percent of a subgroup of 40 subjects, where blood had been collected, had neutralizing antibodies greater than 0.5 IU ml-1 on days 28 and 90 and all had detectable titers on days 7, 14, 28, 90, 180 and 360. All patients could be followed for at least 1 year and remained well. No significant side-effects from this vaccine were noted.
