How can I use a co-routine to yield player damage?

Hi, I am trying to use a co-routine to make my player invulnerable to damage for a few seconds after being hit. I tried the following code, but the player can still constantly take damage. Any suggestions would be great! Thanks!

I have my private bool invul = false; then…

void OnCollisionEnter2D(Collision2D collision)
	{
				if (collision.gameObject.tag == "Enemy") { // If colliding with enemy, execute this block
						HealthScript playerHealth = this.GetComponent<HealthScript> (); //get player health script
						playerHealth.Damage (1); //damage player
						invul = true; //player is invulnerable
						animator.SetTrigger ("Hit"); //play hit animation
						StartCoroutine (InvulWait ());
						}
		}
	private IEnumerator InvulWait() {
		yield return new WaitForSeconds (2); //invul time
		invul = false;
		}
		}

Assuming this is the only point where damage is given, you need to change line 3:

  if (!invul && collision.gameObject.tag == "Enemy") { // If colliding with enemy, execute this block
