I last had flu, the bone aching shaking wipeout flu, not a cold, 50 years ago. I have never had a flu jab, and This year I have had two bouts, one in June wtf and coming out of another now. 

Speaking to a couple of friends of a similar  age who are also very healthy as a rule, share similar stories. I don't travel at all, but they both have had exposure to international work environments.

I have clearly not gained immunity from exposure after my first June episode. 

I'm not mentioning the c word here because that has not been diagnosed. The word is there are some plain and simple nasty flu strains floating around the world these days. And if that's the case, a flu jab  seems like an even less effective proposition than  when flu was somehow predictable, a jab was  based on what strain is flourishing in Australia and it would still get office workers, school kids and OAPs in homes.

Any thoughts or insights?

 Taking vitamin D and maybe some peptides to boost immunity 

 hastily looks up peptides. Old and dumb, I deserve to get flu :)
