Interesting how different Medical systems work. I live in the UK and I received a letter from my General Practitioner (Local Physician) this week asking me to come in for my FLU jab as I am in one of the risk categorys, due to being under treatment for Cancer. I did consult with my oncologist for advice he said yes have it before I start Radiations treatment. (Due to start 1st of Nov.) Needless to say I have now had it. Just interesting how the UK medical system picked me up as a potential at risk person due to my illness.
