Is there any recognised link between the h1n1 flu vacination and pityriasis rosea please? I had this vacination about 5 weeks ago, developed a herald patch about three weeks ago and the first of several waves of rash over the past two weeks? Thank you.
Hello, H1N1 and satyriasis are not related to each other. Satyriasis is a not infectious disease and has got no relation with H1N1. Hope I have answered your query. Let me know if I can assist you further. Take care
