    I've never had the flu shot, but I'm thinking this year is the year. Last year was the first that my boyfriend and I lived together. I've never had the flu, but he seems to get it every year. I know vaccines are ridiculously safe, but these findings are kind of unsettling. icon_confused.gif

    Ridiculously safe, yes, effective this year.. not so much.

    I've had 2 strains of flu this year, both post vaccine, and confirmed influenza.

    I have never had a flu vaccine and I've never had the flu... That's funny

    I had the flu at least twice when I was younger, but never after the US Army, and later the VA, started giving annual flu shots (mandatory in the Army). I'm scheduled to get mine this month, and I wouldn't go through the flu season without it.

    the only time i've gotten vaccinated, i got the flu shortly afterwards, i'd have to think about getting vaccinated again.

    My lab has made it mandatory this year, unless it's against your religion. Refusal is otherwise griunds for termination. I have no intention of getting it, so I may be job hunting soon.

    Same here. When I used to get the vaccine years ago, I got the flu every year. Now that I don't get them I never get sick anymore!

    I wouldn't necessarily trust anecdotal evidence.

    Both my bf and I had a terrible, terrible flu (out of work for two weeks, not recovered completely for almost 6 weeks) almost 20 years ago, when neither of us had a flu shot. I've had one every year since, and haven't got the flu since. My bf never gets the shot and he hasn't had the flu since.

    The only year I've ever had the flu is the year ice got the shot.

    However, here's my view on it. I have a very strong immune system, and I live a very healthy lifestyle with excellent hygiene. As such, not only am I extremely low risk for infection, but I am extremely low risk for getting over it easily without significant complications. I survived Norwalk in res. I can survive the flu.

    Now, since flu vaccinations are very limited in dose, I choose to leave these limited doses for those who are higher risk: the young and elderly, health care workers, public servants, etc. I'll skip vaccination day.

    I've never had one. Maybe I would if I was prone the flu, but usually when I get sick it's just a cold that lasts a few days. No fun at all.icon_sad.gif

    Like some others, the only time I seem to get the flu is when I get the shot. I stopped taking the shot after I got out of the military. I don't recall getting the flu since. But then, I don't always recall what I had for breakfast or what color socks I'm wearing, so for what it's worth, that's my perspective! LOL

    Correlation does not equal causation.


    Just because you get the flu shot and then get the flu does not mean that the flu shot "gave" you the flu.

    Vice-versa, just because you didn't get the flu and didn't get the flu shot does not mean that no flu shot = no flu.

    What about people who don't take the flu shot and still get the flu? Then no flu shot = flu. Or people who get the flu shot and don't get the flu. Then flu shot = no flu. Making assumptions like this does not work.

    A vaccine exposes your body to a particular strain of the virus, not to all the strains. While you may be protected against one strain, like H1N1 (as the article discussed), you may not be protected against the pandemic strain. Also, labs can only do so much since they're pretty much trying to guess which strain will be the most common that season... and not to mention the whole microevolution thing.

    One reason why people get the flu, too, after they've taken the flu shot is that they got the shot too late and had already been exposed some other way, letting that virus replicate in your body's cells instead of developing a resistance to it beforehand. You may still get the flu after taking the shot, but you may not get as sick (if you hadn't received the shot).

    But I wake up in the morning, and the sun rises. Thus me waking up causes the sun to rise, right?

    The flu shot does not protect you from the flu. There are only 3 strains included in the shot, and those are picked for the likely hood of being the most virulent/prevalent for the UPCOMING season.

    What the shot DOES is lower your degree of illness if you do get the flu. Thus saving lives of the elder, immunocompromised, children and those with lung diseases. Thus decreasing health care costs with hospital stays.

    If you do not get the shot and do get the strain that was in the shot, your symptoms and loss of work can be doubled.

    It is in the best interest of everyone, to get the flu shot.

    A. Correlation does not imply causeation.

    B. What was the rate vs the general population?

    C. What starin were they vaccinated with/for and what strain was going around?

    D. Ferrets don't respond to the flu the same way as humans do.

    E. Methods

    If I may, Doug's theory about this.

    The flu shot is killed or split virus. Your body reacts. It tries to and succeeds in producing antibodies via t helper cells, then the production of t killer cells.

    This takes time and can often take up to three weeks. During this window, if you are exposed to the live one, which unlike the vaccine is growing and aggressive, your body, already compromised by struggling with the vaccine, has to work that much harder so symptoms are worse. The sooner there is exposure after the vaccine, the rougher the ride.
    Now consider that many flu vaccines are a cocktail of three or four killed viruses and your body is REALLY busy trying to incubate antibodies and a cold (yet another virus) can be much more severe.

    I always tell people to be fastidious in handwashing, avoiding possible exposure during their first three weeks after a flu vaccine. After that, you're good to go.

    Sometimes you just have to let your body build up an immunity on its own.
