Forget the flu vax I have not had one since 1966. I have not had any virus since 2005 when I started taking vitamin D3 supplements. Sunshine/vitamin D3 is the preventative and cure of respiratory viruses.
i take d3 as well. especially make so in winter, i don’t get much sunlight.
I can’t remember the last time I got
the flu or the flu shot. I never get
either. Never had shingles/pneumonia/whooping cough vaccine either.
Had MMR as a kid.
