What state are you in? In the west the ratio of Fujian/Panama is 3 or 4 to 1. In the Midwest there seems to be a bit more Panama (but I suspect the ratio will go to 3 or 4 to 1 like it is in the west).
Infection with Panama will offer some protection, and exposure to a "live" vaccine may offer more protection than the dead virus in the current vaccine.
Incidentally, we all had the flu last year (except my husband who got the shot through work). It was the sickest I had been in years. I rarely get an illness with a cough and I was hacking up a lung for the better part of a week. Painful, painful coughing. My daughter, who develops a cough if she stubs a toe, was coughing and he, again, only had a minor cough associated with it.
BTW, appreciate all your information. Thank you.
