"CDC: Flu shot less effective this year because current virus has mutated"

QuoteWhile this year's version is not as protective against a mutated strain, it can still decrease the severity of illness caused by the virus. It can also protect against other circulating strains of the virus, which is why the CDC still recommends getting the vaccine.
Quoteif you do start to see flu symptoms -- fever, sore throat, cough, body aches -- it's extremely important to begin taking antiviral medications as soon as possible.
:-[ Not good news for those of us with asthmatic children, especially.
Thanks for posting it, Links-- I was just coming to do that very thing.
They always seem to say something like this every year. The flu shot is never a guarantee. It's a best guess at what kind of virus will be around the next flu season because they have to start making is many months ahead.
Here's the CDC page about it.
http://www.cdc.gov/flu/professionals/vaccination/virusqa.htm (http://www.cdc.gov/flu/professionals/vaccination/virusqa.htm)
I know this is an old post, but I wanted to share. Hospitalized for the flu:
(http://2.bp.blogspot.com/-FZ7ce_rdspM/VJEgWSs5fWI/AAAAAAAACTo/KOQ8xS5rCYc/s1600/hospital%2B1.jpg)
3 hours in ER, adult dose of ephinephrine, 7 doses of albuterol, constant oxygen
2 nights in PICU, constant nebs and oxygen for first night and part of second day, steroids, Tamiflu, slowly weaned off over following 24 hours
And he'd gotten a flu shot. In fact, since he's egg allergic, he's always gotten his flu shot at the allergist's office. This year for the first time, he had a reaction to the egg protein in the shot, getting a welt the size of a softball about 24 hours post-shot. Since his reaction wasn't systemic, the allergist said they would probably continue to give him the shot, but they would spread it out between both legs. I wasn't sure what I thought about that suggestion, but after this year's experience, I'd rather deal with some itchy redness for a day than go through this again. Unless he becomes anaphylactic to the shot, we'll keep getting it.
Btw, he got home yesterday and is doing much better now! (And no, he doesn't have asthma. His younger brother does (who thankfully still shows not signs of flu) but his lungs have always been healthy.)
Oh, this is SO scary. I'm so glad that your son is okay now.
One of our community lost a child to the H1N1 pandemic several years ago. They have become tireless advocates for seasonal influenza vaccinations. :heart:
The nice thing about getting annual vaccinations year upon year is that there is a "library" of immune responses to different strains. I'm hoping that offers our DD some protection, as her egg allergy has prevented her from being vaccinated up until 3 years ago-- so she's only had those 3 vaccinations, and she gets so ill from anything upper respiratory. DH and I have both been getting them for 20 years.
So glad he is ok!
So glad he's OK.
I obviously knew he needed help or I wouldn't have gone to the ER, but what really scared me was the speed with which they moved the moment they saw him. "Holy $#!#, it's that bad?" And then again a few minutes later in his room, when one of the nurses said "He needs Epi." Being a food allergy family, I knew exactly what that meant. Same feelings all over again.
I'm very glad it's over.
Thanks for all your support
Ay yi yi, glad he's OK now!
If my 24-year-old-first-year-of-teaching-knows-it-all-son doesn't get his flu shot today, I'm going to wring his neck.
Seriously, I don't know what I'm going to do with him. :rant: :tongue:
Oh my goodness--that is so scary. I'm glad he's okay.
So my mom was prescribed Tamiflu by her doctor. She got a flu shot, but of course, that may not help. The nurse said Tamiflu can act as a preventive. But for how long. If she takes it now, if she is exposed to the flu in February, will it protect her?

no - you would have to take in continually which is not a reasonable option.

I kind of wondered that, but figured not. Our youngest (with asthma) is on Tamiflu preventatively right now, which should give us enough time for the germs to exit the house, but he'll still be vulnerable if exposed elsewhere later. *sigh*
This is not medical advice ... ask your own docs if you have ?s .... but interesting ....

I used tamiflu once, several years ago. It seemed to help. I mean, I felt better sooner than expected. Did it work, or was it a placebo effect? Or a milder flu? Who knows. I had assumed it was the drug, but maybe not.

I'm not trying to sound like an idiot, but didn't we discuss elsewhere that illnesses don't mutate that quickly? (Ebola) so how does the flu mutate that much in just a few months?
I always thought the issue with the flu shot was that there are multiple flus floating around and they guess which ones are likely to be most common. And sometimes they guess wrong.
I am with you SL - they guessed wrong.
I have not found Tamiflu to be helpful in the past but by the time I must up enough energy to make it into the drs office, I am probably past the point of no return.
This year, my dr doesn't want to see anyone with the flu - if you think you have it, they will call in the Tamiflu (and she doesn't call in any meds usually, she wants to see you). But I think they are trying to cut the exposure risk down to others.
SL, I don't understand the details as well as a doc ... good ?.

Three days later, the feisty 3-year-old was dead, the cause attributed to complications from influenza.
So sad. :-[
About Tamiflu...
It can be used for prophylactic treatment, usually when another family member has the flu. I've never heard of them using like you said Mac as preventative and would probably refuse it for that purpose.
Every.Single.Year! there is a shortage of Tamiflu. Early in the season too. We are out and cannot get it.
All doctors should go the phone route. I've had the flu and would've needed to be carried or taken by ambulance I was so sick. Don't spread it either.
Doctors need to be sure it is a probable case before prescribing though. I've had people come in, drop off a Tamiflu rx and say I'm going to run across the street to the store then I will be back. They aren't coughing, sneezing, don't look very ill. First, you probably don't have the flu if you're out shopping. Second, if you do, don't go out in public and spread it!! Third, someone very ill with the flu could really use that Tamiflu that you don't need.
And my biggest pet peeve, a stomach virus is NOT the flu!!!
Could those people, at let some of them, be getting the rx filled for a family member?
No, it's for them. The ones I mentioned are regular customers I know, and they were filling for themselves.

That happened to us a few years ago and a compounding pharmacy (actually a local Walgreens) was able to make it. Our doctor has always had DD come in for the flu and prescribed Tamiflu if she tested positive. Our plan before DD could be vaccinated called for us to take her into the doctor for testing at the first sign of possible flu symptoms.
A fifth-grader at our local elementary school died from flu just before Christmas.
I think I came down with it on Christmas Eve/Christmas Day. I didn't go to the doctor for a test but the symptoms matched. It took me a solid week to feel better. I don't think I've really had the flu before. It was the achy joints I had that make me think this was my usual upper respiratory infection. I was vaccinated this year.
I feel very certain that the Tamiflu worked for me. I realized I was getting the flu very early since I was with my son at the hospital. If nobody near me had been diagnosed, I probably would've gone to bed early when it started to hurt to cough, not realizing that I had something worse than a bad cold. Because I got the Tamiflu so quickly, I was only sick for another day or two, with asthma symptoms lasting a few more days. Catching and medicating it early worked wonders. DS2 never got the flu, though I can't say that was the Tamiflu he was taking preventatively, or just us being paranoid about his exposure to his brother.

They can (and do) absolutely guess wrong. And it's been a very long time since I studied anything resembling genetics, but why couldn't a virus mutate quickly?
Quote from: 2ndGenAllergyMom on January 06, 2015, 05:33:40 PM
but why couldn't a virus mutate quickly?
When the conversation was about Ebola, all the experts said things don't mutate quickly. But now, when it's "just the flu" they say it mutates in just a few months.
It just sounds like "they" make it up as they go along.
Influenza viruses are said to mutate more quickly than most. I don't know whether that is fact or just what "they" say. But also, there are different types of mutations. To mutate enough to make a vaccine less effective could potentially be just one "misspelling" in the DNA code. That would be a very quick mutation. But other things (like going from one species to another, or becoming airborne) might take multiple changes. That would take longer.
That makes sense. (Science and I never got along well.)
Either way, I do still feel getting the shot is beneficial. With a lesser mutation it is probably still going to offer some protection. And if I understand correctly, the shot usually covers a few different flues. So, if one mutates, you are still well covered for the others.
My son doesn't agree. But now that we get it at the pharmacy he's much happier. It seems it was the anxiety of travelling so far, and sitting and waiting, which led to him feeling sick after a shot. The pharmacy is closer, we pop in and rarely wait even five minutes and it's done. The last two years, no issues.
I am curious about this, and wish I had the time to research it. What hedgehog said does make sense though.
Each flu shot covers three strains of the flu, I'm pretty sure.
There are trivalent seasonal influenza vaccinations, and also a less-common tetravalent (which is what DD got this year)-- and yes, the strains are chosen VERY late in the previous flu season, which usually provides clues as to which strains are likely to prevail the following autumn in the N. hemisphere. Just not always.
The flu is a rapidly mutating virus because it is comprised of subunits-- which means that if ONE subunit is new, a simple recombination is all that is needed to reshuffle and make a whole library of "new" or novel flu viruses. H1N1 is an example of this subunit thing in action-- H3N1 is a different virus, although the N portion is the same, your immune system may not be very effective at fighting it off, even if you possess antibodies for H1N1.
An emergent virus that is HIGHLY effective can create a pandemic that is rapid-moving because of a naive population (that doesn't resist infection, basically)-- it's a complete failure of herd immunity. Swine flu was an example of what a "vaccine-free" pandemic tends to look like, for anyone that wants to know what a world without flu shots would look like now.
Such an emergent strain also outpaces the (antiquated) method of producing the majority of the flu-vax doses, as well, since it takes MONTHS to complete.
Getting flu jabs year after year does allow your immune system to built a "library" of subunits that are recognized, however, and buys you some insurance for a year like this one.
Our perception of efficacy when talking about relative estimates is more of an issue than mutation. If one's expectation that even the most perfectly matched vaccination confers absolute immunity then lesser degrees often seem pointless. The end goal of vaccination is to prepare the body before it encounters the wild virus, allowing it some defense in order to survive, not to repel it outright. Therefore the benefit outweighs the theoretical risk both individual and herd.
Vaccinations don't make us healthy or completely immune they only increase our likelihood of not dying from encounters with the wild virus by modifying severity.
I have absolutely no medical background or chemistry or biology but that's what I understand from both the ped's office and reading the CDC forms. I'm sure someone can improve upon my description and wording.
Yeah-- word on the street is that this year's trivalent jab is about 33% effective in terms of protection, as compared to 75-85% in a "good match" year. It's still far far better than not having it at all.
