Have you had Flu?

Let me ask you a simple question to start with - - have you ever had the flu? I did, it was back in 2018. I’ve been to the GP for my annual check up and he suggested to me that whilst I was there he would give me the flu jab. Opportunistic jabbing! One week later I was sick in bed with what I thought was the flu. I was really quite unwell and I thought it a bit odd that despite him injecting me with the Flu jab, I had come down with the very thing from which I was seeking immunity! Silly me.
