Line unpricked pastry shell with a double thickness of heavy-duty foil.
Bake at 450 degrees for 5 minutes; remove foil. Bake 5 minutes longer. Remove from oven; reduce heat to 350 degrees.
In a mixing bowl, beat the cream cheese, sugar and vanilla until smooth. Add eggs, beating on low speed just until combined. Pour into pastry shell.
Stir jam; drizzle over filling. Cut through filling with a knife to swirl the jam.
Bake for 25 to 30 minutes, or until center is almost set. Cool. Refrigerate overnight.
Let stand at room temperature for 30 minutes before slicing. If desired, pipe whipped topping around pie edge.
