How to avoid colds and flu

These past few days I’ve felt rather listless, had vaguely aching limbs, a mild headache that comes and goes, and a dull, throbbing ache where I had my flu jab more than a month ago…could it be that I’ve actually caught flu, and that the vaccine has held off the worst of the symptoms? That throbbing pain at the site of the jab seems to be the smoking gun, but I’m not sure whether there is some persistent immune response at the site of an injection that might cause recurrent symptoms when one is struck subsequently by the live virus…

Anyone know for sure? I’d be interested in qualified comments
