None: A flu shot should not cause symptoms of runny nose, sneezing, sniffling, or cough. Anybody can get cold symptoms before a flu shot or after a flu shot, or before or after any shot, because cold symptoms are common. That does not mean the symptoms are FROM the shot. It's just a coincidence in timing.
