Back to reality...never had a flu shot, never will.
Pity for those who take the shots instead of the summer sunshine and winter D-3 supplements. The shots vary from minimally effective to 70% or so each year according to the NIH. The Vitamin D is 100% and good for ALL seasonal viruses. A megadose of D-3 in my experience (x3 with other people) is effective in ending a case of flu no matter how severe in under 12 hours.
