| [study of the properties of a tissue smallpox vaccine manufactured by the moscow research institute of viral preparations]. | the tissue culture vaccine against smallpox has some important advantages over the dermal preparation: it is free from bacterial contamination, contains no serum proteins, and suitable for intradermal inoculation with jet injections. the virus for the tissue culture smallpox vaccine is grown in japanese quail embryo cultures controlled for the absence of contaminating viruses. in trials of the tissue culture smallpox vaccine in 800 revaccinated volunteers no untoward reactions or complications w ... | 1977 | 333762 |

| [comparative restriction enzyme analysis of the genome in variola virus strains from the russian collection]. | comparative rflp analysis was for the first time performed for 21 variola virus (varv) strains of the russian collection with 20 amplicons covering the total varv genome. the amplicons were synthesized in the long polymerase chain reaction. a database useful as a reference for identifying varv strains was generated. varv strains isolated in different geographical regions were compared and proved to vary mostly in variable genome regions. each of the dendrograms constructed included three cluster ... | 2004 | 15285611 |
