Flu vaccine

My son had his wednesday last week and been fine. It took all of 30 seconds and he didn't even flinch. It's a tiny little syringe, smaller then a Calpol one and she just popped it in each nostril and pushed the syringe part. Not sure if he was amused as it was somewhere different and someone new but he just happily sat there. He's been fine since too, no flu like symptoms or anything so all worked out for us. Hope that helps a little 😊
