Up to you if you have it or not! Since being diagnosed my GP insists. It has been three weeks since I've had the flu shot and no discomfort at all. I am a little rattly at night but that is more to do with if I go and check the chooks late or head out for firewood and struggle with the night air...……..pretty chilly here as I am more than 600m above sea level.
Last year I had the injection but still managed to pick up colds, 3 in total with 6-8 weeks for one of them. That suggests to me the immune system is still not right and hopefully the flu shot is an insurance not to get the flu!
Take care
