<p>The invention relates to DNA constructs encoding a safe, selectable marker, other than an antibiotic resistance marker; vectors and/or cells including said constructs; and vaccines based on said constructs for use in animals and particularly humans. The safe, selectable marker being a marker than confers resistance to an agent, other than an antibiotic, which would otherwise deleteriously affect the growth of a cell in which said construct was placed.</p> |
