The last time I knew for sure I had the flu was in 1959. I was bedridden for six weeks and almost died. Since then, I have had a flu shot every year and after we got married in 1972 so did my wife at my insistence. We've never had symptoms of anything more than a mild cold even though we both got old. Until this year. This year at Christmas our youngest granddaughter was visiting and obviously had something. On December 30 both my wife and I were sick. It wasn't until the last week in January that we thought we were about recovered. Then on February 5 we relapsed putting us both down in bed for a couple of days. By then I had to concede to my wife's insistence that it was the flu. Naturally, I was puzzled at both the fact that I got the flu and it was pretty bad. Finally, the answers have come forth in this AP article Flu shot did poor job against worst bug in seniors. In summary and in plain language, us old people who had the flu shot didn't build a resistance to the current strain of Type A H3N2. The extremely long article as usual didn't describe the symptoms. But I found this article that clearly listed every symptom we had: Runny nose Sore throat Aching muscles Headache Cough Nasal congestion Malaise Fever Watery eyes Aching joints Sore throate Aching body Chills Fatigue Red eyes Red skin Red nose Red throat Loss of appetite Weakness Both of us had a fever for a day, not the same day. Perhaps the vaccine kept us from having a debilitating fever. It is clear to me now that at the moment we felt sick, we should have gone to the doctor and gotten one of the two antivirals oseltamivir or zanamivir, except that we might have been treated with one of the adamantanes to which the H3N2 is resistant. We didn't seek treatment as we did not get the information that the vaccine wasn't working because the CDC didn't know until now. It's been 53 days and we both still have symptoms, though just mild nasal congestion, cough, occasional headache, and malaise (meaning a vague or unfocused feeling of mental uneasiness, lethargy, or discomfort). If you're Medicare age or older and start feeling the symptoms, go get an antiviral even if you have had the flu shot. And in the future, I'll remember that flu shots aren't perfect and not all influenza is the same - for instance the 1918 Spanish Flu struck the adult population harder than kids and seniors. By the way, "they" are offering a large dose shot for seniors now hoping to stimulate a better antibody reaction.
