The invasion by a symbiont of a cell of a host organism, forming a vacuole in which the symbiont resides. The vacuole membrane is formed from lipids and proteins derived from both host and symbiont. Begins when the symbiont attaches on to the host cell membrane which invaginates and deepens as the symbiont enters, and ends when the host cell membrane closes behind the newly-formed vacuole.
