Flu Shot Doing Poor Job of Protecting Older People This Year 205

New submitter Gunilla sends this news from an AP report: "It turns out this year's flu shot is doing a startlingly dismal job of protecting older people, the most vulnerable age group. The vaccine is proving only 9 percent effective in those 65 and older against the harsh strain of the flu that is predominant this season, the Centers for Disease Control and Prevention said Thursday. Health officials are baffled as to why this is so. But the findings help explain why so many older people have been hospitalized with the flu this year. Despite the findings, the CDC stood by its recommendation that everyone over 6 months get flu shots, the elderly included, because some protection is better than none, and because those who are vaccinated and still get sick may suffer less severe symptoms." An anonymous reader adds information about a new drug that treats influenza by hijacking its own infection mechanism. The compound "binds to an enzyme on the surface of the flu virus called neuraminidase. This enzyme is responsible for severing the connection between the flu virus and human cell so it can move on and infect other cells. The new class of drugs — DFSAs — permanently bind to the enzyme, blocking its action and stopping it from spreading further, the journal Science reported (abstract). Currently available antivirals also work by attaching to this enzyme. But DFSAs do so in such a way that the flu virus cannot evolve to be resistant to the drug without rendering itself useless."

    The CDC just keeps shooting themselves in the foot. Admit the problem and QUIT telling everyone to get the flu shot every year. It doesn't work as advertised and should not be relied on a the main defense against the flu.

    - Cochrane Review - Vaccines for preventing influenza in healthy adults

    - Dr Lisa Jackson's out of season influenza vaccine research
    http://ije.oxfordjournals.org/content/35/2/337.short

    Using the proper tools for the job is very important and vaccines work best against stable targets like smallpox. Against the influenza virus it is a total joke. They go to manufacturing in June/July and the flu has 3-6 months to mutate and they wonder why it fails? Give it up. It does not work.

    The more the CDC promotes something that clearly does not work the more people are going to throw out the baby with the bathwater and think that they are lying about all vaccines. Good to hear there are some advances in stopping the flu because the current approach has been a total failure.

      This is a virus, your two main options are to either have people avoid human contact or give them a vaccination. Sure, things like washing hands might help a bit, but ultimately, there aren't a lot of options for something like the flu.

      What's more, you're ignoring the fact that this year it worked for 9% of the people over 65 who got it. That's really not a good number, but it's better than zero and ignores the other people who received the vaccination as well.

        And YOU are ignoring the increased risk of exposure to flu people have by going to wherever the flu shot is administered.

        That 9% number does not stand in a vacuum. There are many other factors and with that protection number being so low, to me it makes little sense to go somewhere and risk greater exposure to other people from which you would get the flu to begin with.

          No, I'm not ignoring that. If they knew what the efficacy rate was like without administering the injections, that would be a completely different thing. But, you can't sit there with the numbers from the real world and judge the doctors for not having access to them before they even existed.

          I said, that 9% isn't a good number, but pretending like they were giving these shots out knowing that whom they would and would not work for is just plain wrong. You're also assuming that these people are shut ins. If they were shut ins, then there would be no point in vaccinating them as they wouldn't be exposed to the flu in the first place. For the folks that actually go outside, they're already going to be exposed, suggesting that this is represents a greater exposure is just the typical anti-vaccs bullshit.

        Insisting that people stay home when they get the flu (and insisting that employers allow it) would actually reduce the incidence of flu quite a bit.

        Meanwhile, note that 9% effective doesn't mean 9% of the people who jot their jabs avoided the flu. It means that the people who got the jab were 9% less likely to get the flu. So, if 1000 people got the shot and they stood a 10% chance (unvaccinated) of getting the flu, 9 people total avoided getting sick.

      The influenza vaccines are the best tool that we have. It's a lousy tool, but oh well, play the hand that you're dealt.

      And before somebody goes off on and thinks this is Scary New News, influenza vaccine has ALWAYS sucked on infants and older people. Precisely the people that the virus wreaks the most havoc on and likely for the same reason (poorly developed or worn out immune system). This year's vaccine seems to do particularly poorly on the strain of B that we've been seeing. But you never really know how good or bad the vaccine does in any given year until you can tally up all the statistics and look at previous years (and fudge a few numbers).

      The bigger news is that Tamiflu is really worse than it was made out to be [bmj.com] (which wasn't so hot to begin with). The usual suspects - money and political influence (but I repeat myself).

    I for one got the flu twice, despite having had a shot. Each time I had different symptoms (including hypothermia) and was told it was a different strain of the virus.
    • And your point is? They need several months to produce the necessary doses and sometimes they get it wrong or it mutates in a significant way.

      Also, this is a sample set of 2 doses and one person. The one time I got a flu shot, I wound up with basically every side effect except an allergic reaction, and would have been better off without it, but that doesn't mean that it isn't good in terms of herd immunity.

    • Hypothermia isn't a typical Influenza symptom.

      If you didn't get a nasal swab for Influenza then you probably didn't have influenza - clinical diagnoses just aren't very accurate (about 50% even in the face of an epidemic).

    With homeopathy, there is no need to test the results of taking a substance, putting it in water, then constantly diluting the amount of that substance in the water until there is only one molecule of that substance left in the water. Because water has such great memory, it "remembers" the powerful healing abilities of the substance while completely forgetting all the urine, feces, saliva and other bodily fluids the water has come in contact with.

    Because of this miraculous memory, that one molecule has more healing and restorative powers than the most powerful, science-based vaccines, vaccines which do nothing except make people sick and keep big pharma rolling in the money like they do for afflictions such as smallpox, rinderpest and polio.

    Unlike traditional science-based vaccines, homeopathic medicines can be done in the safety of your own home. No need to get doctors involved with their 8-10 years of medical training and untold hours of visiting patients, doing research and consulting with other so-called "medical experts". One can dispense with such safety protocols because no matter what, homeopathic medicines have been rigorously tested under the most stringent conditions including having a crystal suspended above them while the dilution occurs.

    Not once has any side effect ever occurred from taking a homeopathic medicine. That one molecule in the water won't let it happen because of the exponential power it has from being the sole piece left of the original substance.

    So do yourself a favor and pass on traditional vaccines and medicines. Homeopathic cures are the wave of the future, able to solve the world's medical ills in a single glass of water. It's only because the medical community doesn't want you to take matters into your own hands bypass the time-tested methods of science-based medical trials that homeopathy has such a bad rap.

    Ignore the naysayers, the ones whose ills have been cured by Western medicine, they're just anomalies. Homeopathy is where it's at.

        Well, you clearly understand nothing about homeopathy. You think it's about diluting until there is "only one molecule of that substance left in the water." But, at proper homeopathic dilutions of 10^100:1 (100 10x dilutions), you wouldn't have one molecule left among all the other matter in the universe. No wonder homeopathy gets a bad reputation, when quacks are handing out dangerously under-diluted mixtures with an entire molecule remaining --- that'll screw up all the imprinted energy resonances!

        • Yes, I know what homeopathy is really about. I decided to do the one molecule part to show how absurd it is rather than trying to come up with a good example of how many millions of gallons one would have to go through to find that one molecule after the dilution.

      I actually considered this once. I don't pay anything directly because it's a "covered" item in my health plan, but I would pay $25 out of pocket if I got one. So here goes:

      When I was younger - in my 20s& 30s I got a flu - or flu-like symptoms requiring I miss work for 3 or more days - four times. I started getting the flu vaccine about 8 years ago, and I haven't had the flu for about 11 or 12 years.

      Let's say my typical chance is once every 5 years. (4x in 20 years). If I were only to get the flu once every 10 years (56% effective in my target age group), that means that, on average I will miss 3 days less of work in 10 years. I'm a consultant, so I bill $150/hr, and I get nothing if I don't work. Whether I show up at the office or not, I pay for rent, electricity, licensing, insurance, etc. So...3 days at 6 billable hours in a typical day is $2700 is lost income (note I'm not counting the 3-4 hours of admin time a day, which is all rolled into those billable hours). $2700 a year over ten years is $270 a year, or an 11:1 payback on my "investment" of $25. As a bonus, I don't end up paying for a doctors visit, or for medications, or for the general crappiness I feel, or take the chance that my wife and daughter are then more likely to get it as well. Break even, without medication costs and such, would be around $13.60/hr.

      If it were the worst case of 9% if I were over 65 and still working, then we're really talking statistical, but that would mean a theoretical reduction of 18 hrs/5yrs*9% = $49 a year return on a $25 flu shot, plus the above associated effects and medical costs, and the chance of dying from the flu because I'm just old and more likely to get a secondary infection.

  • One of the reasons I don't get flu vaccine is because I expect the corporations to give you last years stock (which is no good for the current year) because it's cheaper then making new stuff.

    The other reason I don't get flu vaccines is I don't catch the flu. Probably because I have NEVER gotten a vaccine to begin with.

  • that if you are in an age range in which the flu vaccine is more effective, it is your civic duty to get one so you lower your chances of passing the flu onto those with which vaccines are less effective.

If all the world's economists were laid end to end, we wouldn't reach a conclusion. -- William Baumol
