The only effect I can think of is generally giving a short-term immune boost just from having antigens in the body, like you would not catch a flu a few weeks after you had a cold.
Obviously, a "cold" does not immunize you against a "flu", but it raises some short term immune defenses.

That's all.
It would be much safer just to give people a cold virus.
