Description
PATENTKRAV: 1. Vaccine mod hepatitis B-virus hos mennesker, kendetegnet ved, at den indeholder en effektiv mængde hepatitis B-overfladeantigen (HbsAg), som er fremstillet ved at man har ladet en hvirveldyrcellekultur trans-ficeret med en rekombinant viral ekspressionsvektor, som er i stand til i en transformant hvirveldyrcellekultur at udtrykke en DNA-sekvens, der koder for modent hepatitis B-overfladeantigen (HBsAg) uden nogen sekvens, der koder for HBsAg-forsekvens, hvor den nævnte HBsAg-kodesekvens erstatter kodesekvensen af et viralt vektorgen, således at den er under den rette styring af promotoren for det virale gen, som er heterolog for HbsAg, vokse under sædvanlige betingelser i medium, indtil det nævnte HBsAg var produceret deri, og har udvundet det nævnte HBsAg, i blanding med et egnet medium til anvendelse i præparater, der indgives for at forhindre virusinfektioner. 2. Vaccine ifølge krav 1, kendetegnet ved, at translationsstartcodonen for DNA-sekvensen, som koder for det modne HBsAg, er lokaliseret i den oprindelige position, der blev indtaget af translationsstartcodonen for det virale protein, der normalt styres af den virale promotor, eller inden for ét basepar fra den oprindelige position . 3. Vaccine ifølge krav 1 eller 2, kendetegnet ved, at den rekombinante virale ekspressionsvektor er SV4O-vektoren. 4. Vaccine ifølge krav 3, kendetegnet ved, at den rekombinante virale ekspressionsvektor er valgt blandt pSVHBSA, pHBs348-E og pHBs348-L fremstillet som angivet i beskrivelsen. 5. Vaccine ifølge et hvilket som helst af kravene 1-4, kendetegnet ved, at hvirveldyrcellekulturen er opnået ved transformation af CV-1 linien af abenyre-fibroblaster. 6. Vaccine ifølge et hvilket som helst af kravene 1-5, kendetegnet ved, at det nævnte HBsAg er secerneret i adskilt partikelform til dyrkningsmediet. 7. Vaccine ifølge krav 6, kendetegnet ved, at det nævnte HBsAg er udvundet i form af 22 nm partikler.
