Stuff you should read about Novel A/H1N1 not-seasonal "Swine" (nee Mexican) flu of 2009/2010

When I started getting flue shots quite a few years back, I was interested to know if they did any good. Were thy effective? did they save lives?
This information was surprisingly hard to track down and sort out. It did eventually seem that those that had a flue shot were 50% less likely to be hospitalized for the kind of symptoms that are associated with flue, but there were no double blind studies to really sort things out. It is possible that more affluent and educated people get flu shots and may be less susceptible for other reasons. We have to take a lot of this on faith.
I have just had my flu shot by the way, but if anyone knows of such good studies do please post them.

If you have the opportunity to get a vaccine, for either kind of flu, get it. You don't want to go through this. Two weeks later, and I'm still not recovered from the flu.

Miss Cellania, I'm really sorry to hear that. It goes away eventually... By the way, that's a symptom. If you know somebody who says they had the flu, but they got sick on Monday and were back at work on Thursday and don't feel sick at all by Saturday, it wasn't likely the flu.

Sailor: There is quite a bit out there but I admit it is hard to find. In any event, it is complex. The current best guess is that in an average year people between the ages of something like 12 and 65 who are not immune compromised or otherwise in a risky group have a rate of between 80 and 95 percent suppression of serious flu symptoms if they are immunized. In older and otherwise at risk groups the numbers are lower, like 50% or more, but the number of people who don't develop some of the more deadly complications (including death) is markedly lower.

This is mostly known through epidemiological studies across the population. There may be some biases in the data inherent to who gets the flu shot vs. not and other factors but they are probably not strong. It is helpful to note that the theory here is strong.

As I thought the evidence is there, but pretty piss-poor. I shall continue to get flu shots anyway because once I got a flu bad enough that in the US I would have been in a hospital. Luckily I was on my boat in a less developed country so a doctor kindly came out and put a re hydration drip in me on board. He gave me antibiotics in case bacteria had become involved, and all was fine.

... once I got a flu bad enough that in the US I would have been in a hospital. Luckily I was on my boat in a less developed country ...

Could you please expand on that? I do not live in the US, so I don't know the state of their hospitals, but I'd have thought they'd at least have kept you alive.

SQB - in my experience you can't get i.v. fluids anywhere EXCEPT a hospital in the u.s. The little neighborhood clinics like Primacare won't give you i.v. fluids and neither will your dr so you are forced to go to the emergency room. I have been to the E.R. for i.v. fluids once, and was sent home hours later (i.e. i was not admitted, just stayed in the E.R.) I don't know the reason but it drives me nuts to have to go to the E.R. and expose myself to other sick people just to get i.v. fluids.

SQB Texas Reader has it right. And it is a reflection on the cost of health care in the USA. Had I gone to hospital, I doubt I would have got out for less than a thousand dollars or three. Where as in a small less developed country I got a house (or in this case a boat) visit, with an IV and antibiotics, I did not have to stir myself, and the cost was about $40US.
The USA has good medical care but it certainly is not geared to minimizing cost.

In reference to the 50%

Chuck: Very funny. Or, are you suggesting that anyone take that article seriously

Besides, that article does not say fifty percent. It says, again and again, zero percent. It says the vaccine has no effect whatsoever.

Thank you for the explanations. I didn't take insurance and costs in consideration. I understand why health care reform could be in order.
