I'm not actually sure of how a flu jab works...does it introduce the virus in some safe form into your body so it can build up an immunity..or what ?
I had the jab some years ago, and felt like death for 24 hours.
I know plenty of other people had the jab with no day after effects !!!
Is it because perhaps some people who havnt either had the flu or the jab for years and years react badly.
you CAN NOT get flu from the flu jab. Period. Any illness following it is purely co-incidental.
