title: Studies on vaccination against papillomaviruses: a comparison of purified virus, tumour extract and transformed cells in prophylactic vaccination.
abstract: Calves were vaccinated with two preparations made from one cutaneous fibropapilloma induced by bovine papillomavirus type 2 (BPV-2). One vaccine consisted of homogenised tumour; the other contained purified virus only. Both produced resistance to a heavy challenge infection of BPV-2. One calf in the vaccinated group developed a small tumour and rejected it earlier than the control calves. It would appear likely that the prophylactic immune response was induced by viral structural proteins only and that tumour-specific antigens are unnecessary. Bovine fibroblasts were transformed in vitro by BPV-2 and administered as a vaccine; immunity was not induced.
