I've just come across this article, I'm 42 next week, a life long brittle asthmatic. I won't go anywhere near vicks vapour rub, I was frequently having bad attacks as a child (8-15) at around 12 I was poorly, mum put vicks on my chest and within 30 mins I was on my way to hospital  (I was then a red card holder in medway) mum called I'm on my way, prepare to receive me, but this time, on route, I foamed at the mouth became cyonized and remember so clearly thinking I won't make it there. I swore blind it was the vapour rub that caused something nearly took my life! There was something so dangerously different so quickly that day (quicker than usual) I had oxygen at home, BEEN ICU before and after, but that's the only time I remember being terrified. I've always felt no one quite believed me, but as the person who lives it, I knew, it's not just little people this may affect, I'm so glad I read this article
