Hi I have PV and take (Clopidogrel and hydracarbimide daily). After reading the link here I contacted my GP with regards to the flu jab, especially since I'm just recovering from a 2nd chest infection in the past few months. I was told I didn't meet the criteria so wouldn't be considered due to shortage of the vaccine, if I'd asked 4 years ago would have been given it. Crazy really because I wouldnt have even considered it back then. You can pay for the vaccine from boots but still dont know if I should have it or not.
