2009 H1N1 flu strain will be in next season flu vaccine

By Miriam Falco
CNN Medical News Managing Editor

The 2009 H1N1 flu virus, which has been circulating since last spring, sickened millions and killed at least 15,000 people worldwide, will be included in the next seasonal flu vaccine when it becomes available in the fall, health experts in the United States decided Monday.

Every February, the Vaccines and Related Biological Products Advisory Committee advises the Food and Drug Administration on which flu strains to include in the next flu shot or spray.

The committee is following the recommendations of the World Health Organization, Dr. Jerry Weir, the FDA's director of the Division of Viral Products, told CNN.

"This is the same process we go through every year," Weir explained. The selection is made early in the year to give flu manufacturers enough time to make enough vaccine by September or October, when health officials recommend people get vaccinated. Pharmaceutical companies need so much lead time because it's takes a long time to grow vaccines in eggs, currently the only licensed method for making flu vaccines.

"The new H1N1 strain didn't exist last February," said Weir, which is why health officials couldn't consider it for the flu vaccine for the current flu season. Once it was determined that this new type of H1N1 flu strain was circulating around the country and the world, flu manufacturers were asked to develop an additional flu vaccine to fight this virus.

The most recent estimates from the Centers for Disease Control and Prevention suggest that between 41 million and 84 million people in the Unites States have been infected with 2009 H1N1 since last April. The CDC also estimates between 183,000 and 378,000 people were hospitalized and between 8,330 and 17,160 people died from this flu since it emerged.

The agency says its estimate vary widely because not everyone who gets sick goes to the doctor, and not everyone who is hospitalized was tested for this flu and because health officials believe hospitalizations and deaths are under-reported.

The following three virus strains will be included in the 2010/2011 seasonal flu shot:

- an "A California viru," which is the pandemic virus H1N1 virus that caused so much illness in the past 10 months;
- an "A Perth virus," which is an H3N2 virus
- a "B Brisbane virus."

Weir says now that the three specific strains have been selected, manufacturers can now begin producing the new batch of seasonal flu vaccine.

For those concerned about getting the flu now, the CDC continues to recommend getting the separate H1N1 vaccine which is now widely available.

    You just ensured that I will never get a flu shot again by including this in the seasonal vaccine.

    I was received both flu vaccines this year. I received the flu shot in Oct and the H1N1 in November. In February I got H1N1 flu. I weathered it, but my doctor was concerned that I would avoid the shots next year. I will take the shot when it is available. We all need to.

    They need to do something. My five (5) grandkids got the H1N1 shot but there was not any available for their flue shots. What kind of government and CDC do we have out their besides their idiotic fights for their selves and not the citizens. I would give up my shots, I am a disabled veteran to give to my grandkids. Between the CDC and our Government and these companies, they all need to get together and get their STUFF together.

    If you were vaccinated with the H1N1 flu shot early this year, it is necessary to be vaccinated in the fall with the seasonal one ?

    Well I guess I'm finished getting my annual flu shot. I've gotten it for the past 13 years. I do not want the H1N1 vaccine. Its a shame it'll be all or nothing.

    Awesome...so now if you opted out of getting the h1n1 paranoia scare monger vaccine last year because of perceived safety concerns but still got the normal seasonal flu vaccine that's relatively tried and tested. You now are pretty much forced to get the h1n1 vaccine because they've mixed it with the seasonal flu shot or not get a shot at all.

    Excellent....I guess I won't be getting a shot this year 😉

    Does anyone know someone who has experienced Guillian-Barret Syndrome? I know of 2 cases recently of Guillian-Barret Syndrome (GBS) in the Greenville area occurring soon after the swine flu vaccine (this includes the nasal spray). This is an autoimmune disease that attacks the spine and peripheral nervous system, resulting in paralysis and difficulty breathing. Recovery will take 3 months to 1 year or longer and requires blood plasma transplants as well as a lot of physical therapy. According to the CDC, this reaction is very rare (1-2 in 100,000). However, after seeing this happen to my friend and spreading the word, I have heard of 10 other people who have had this before. I know these are anecdotal reports but makes me wonder if GBS is something that is under-reported. I understand GBS can occur after sickness. My friend had not been sick at all. I am very concerned the public is not aware of the risks of flu vaccines. This is something you don't hear about on the news. Please encourage anyone considering the swine flu vaccine to research this rare but deadly side effect.

    Well, what do you do if you got the H1N1 already? Isn't this overload of it if you get the seasonal vaccine next year and get another dose of H1N1? Why didn't the article address this issue? Millions of people are in this situation.........

    My son received both the seasonal and H1N1 vaccines this year. Is there any danger in his receiving the seasonal vaccine for next flu season that will include the H1N1 vaccine since he's already been vaccinated? thanks.

    Why can't we leave it up to the people to decide if they want either or both of the vaccinations instead of having the Flu and H1N1 together. This means I will never get the flu vaccine again or my children.

    Meleah,
    You are very correct to be worried. The only person in our family to recieve this vacine, was a R.N. who was healthy the day before the shot and now 3 months later has all types of problems. Her daughter and sons and grandaughter did not recieve the vaccine...and they are all fine. They are now taking care of a very sick mom. She will never return to work. Her doctors have no answers for her. They have done all the test that they can.
    She like my husband and me are Native American. He and I went through the H1N1 and took Pau D' Arco(an herb...that surrounds the virus..then your white blood cells can do the work of killing the virus cells off). We were sick for 4 days. We keep this herb in the medicine cabinet. My daughter and her three girls took this as well. All are fine. Many of the children in their school that had the vaccine, are not o.k.
    Now that those that are in "power" to decide what will be in a shot, have decided to include this......I will NEVER take their vaccine.
    My mom was a R.N. and my dad a doctor.....both were worried back in the early 60's of the vaccines that were being added to. They only had me get the very basic shot. I am glad they did.

    I always get a seasonal flu shot. I'm in the administrative side of healthcare and chose not to get an H1N1 flu shot this year. I still do NOT want an H1N1 vaccine, so I'm with the others. If it's all or nothing, I'll do nothing. To the CDC – thanks for nothing!

    Each year three strains of flu virus are combatted by that year's flu shot. There are many viruses, but the WHO/FDA decide on which ones will be most prevalent. Each year, you need to get vaccinated against the current year's strains. That means that if you took the 2009 H1N1 and the flu shot, you were vaccinated against 4 viruses.

    I took both, so I am vaccinated against all 4 viruses. Next season, I will get vaccinated again.

    I have seen where people are wishing to refuse next year's flu shot because it will contain the 2009 H1N1. Do any of those people know that that particular virus may have already been in previous flu vaccinations? Every year, there are different virus strains in the flu shot.

    Do the research and find out what it is all about. Don't take my word for it. Check out the facts. You might find that I named things incorrectly, but you should find out what the deal is.

    You need to get a influenza vaccine every year, as the virus strains included in the vaccine change every year. Adding the new H1N1 strain to next year's vaccine is no different than adding a different strain from any other year. Wake up people and educate yourselves! You are panicking because the media is making you panic. Media grant us the opportunity to inform ourselves so use it to educate yourselves about the manufacturing process and virus strain selection process of the seasonal influenza vaccine. This is exactly what should be done – the "new" H1N1(A California virus) should be included in the 2010-2011 vaccine. And for you fearmongerers -did you know there was a different strain of H1N1 virus in this year's vaccine?

    To educate all of you who did not get the H1N1 vaccine because of lack of knowlege. I am in the medical field. The H1N1 is made exactly like the regular seasonal flu vaccine. Did you know that the seasonal flu is made new every year with the most common strains of that years flu included? The reason H1N1 strain was not included was because the out break of H1N1 happened after the seasonal flu vaccine was created. If it would have been included you would have never known, because it is just like all the other flu strains. Education is very important in health care and the media makes this "new" strain of flu vaccine scary. The H1N1 vaccine has the same amount of testing as the other seasonal flu vaccine. That is why there are two this year. There are always risks to getting any immunization, that is a choice you must way, getting the side effects and/or reaction or getting the disease or illness. With out vaccinations, diseases like polio would still be prevelant in our youth.

    In 2009 I got both the H1N1 shot and the seasonal flu shot. I am 60 years old and have had absolutely no problems with either shot. My doctor gave me a card that says my H1N1 shot is good until April 2011. I do not want to overdo my H1N1 protection and give myself the flu by double dosing myself. How do I get a seasonal flu shot for 2010 without getting the H1N1 shot? Seems to me that millions of people will have this same question/problem.

    It is like they pick 3 viruses out of a hat to put in the vaccine. What about the bird flu? Remember that 'panic' a few years ago?

    You will NOT overload on H1N1 vaccine if you received it this winter, then also receive it in next fall's jab. No more than being exposed to the live virus "in the wild" post-vaccination will overload you.

    Got both this past winter, will be getting it again this fall. Vaccines are safe and effective – GBS can happen, but at far lower rates than serious complications of influenza. Play the odds, folks.

    Flu is the flu, be it H1N1 or any other strain. There is nothing magical about this year's H1N1. H1N1's have circulated widely before. Right now it is displacing H3N2 as the predominant strain, just as H3N2 has done to other strains over the years. At some point H3N2, or some other strain will resufrace when the population has lost it's group immunity. Like many other posters have said, they media hypes this into something it isn't. H1N1 is not "new," is just hasn't been seen in a long time. There's nothing unique about the vaccine this year. If you've previously gotten the seasonal vaccine, there is absolutely no reason to avoid the H1N1 vaccine, the process is no different, and it only makes sense that they be combined into 1 vaccine.

    my entire family including a 4 yr old and 5 month old got the virus last fall. Kids hardly had any symptoms, spouse was in bed for half a day and I was sick for 2 days, all in all it was like the regular flu.

    We did not fall for the scare monger tactics. Do not need a seasonal flu vax, but now there is no way we will be getting it. Hopefully people wise up. Be smart, eat a proper diet, wash your hands and stay home when you don't feel well. It is not rocket science.

    It really is a shame that there's so much vaccine fear-mongering out there. The 2009 H1N1 vaccine wasn't formulated any differently than previous flu vaccines. Each year the seasonal flu vaccine contains three flu strains currently circulating – so this fall's flu vaccine won't be any different than vaccines of past years. It typically contains an H1N1 strain anyway. My family got both the H1N1 and seasonal vaccines last fall, and we'll get vaccinated again this coming fall. Flu vaccine efficacy is lower than that of other vaccines, so there's certainly a benefit to getting the H1N1 dose again. I've got a toddler at home, and have no interest in him catching the flu or spreading it to more vulnerable people – like infants and pregnant women – that we come in contact with.

    There is no fear mongerring going on. 100 million people died in 1917 because of a H1N1 strain. The seasonal flu vaccine always includes immunization against the three most prevalent strains out there and H1N1 happens to be one of them. You've gotten a seasonal shot due each year, but because this one has the most popular virus in it this year, you're not going to get it? That's just messed up thinking, pure and simple. There is no reason not to get the flu shot this year.

    Anyone who claims to be in healthcare but spreads this irrational fear of the H1N1 virus is a fraud or an idiot. It is one of the most harmless vaccinations I have ever received. Zero ill effects. Not even a sore arm. Of the REAL medical professionals I know in the real world and meet face to face, not one is avoiding the vaccine. The internet, and the claims people make on it, is a world unto itself. As Jenifer says, it's formulated just like ANY other flu vaccination.

    For all of you who are saying that they won't get the flu shot next year because it will contain the 2009 H1N1 strain don't understand how the flu vaccine is made.

    Many of you probably think that you get the same seasonal shot every year. You're wrong. They make a brand new shot *every* year based upon what strains they think will be in circulation the next year (they choose late Feb and the shot becomes available Sept-Nov). The shot you got two years ago was different than this year and it will be different than next year. Basically, every year you get a flu shot that has never been tested beyond a few limited trials, not just the H1N1 version of the flu shot this year. But the *process* is very well tested and it is amongst the safest known to medicine. Get the shot. Get it every year. It keeps you from getting sick and helps to keep others from getting sick. If there's a shortage let those who need it the most get it first, but if it's available there's no need to wait.

    Also, there's no evidence of "overload" if you got it this year and also get it next year. In the clinical trials, they included giving two shots only a month a part, and it was shown to be safe (but not necessary which is why we only needed to get one). Also, public health officials think of these things and would never make the vaccine combination this way if they had any reason to believe it would cause problems.

    All of this info is readily and publicly available from the CDC and through reliable sources.

    three years ago I took the flu-shot for the first time. Though I was protecting my mother who has chronic lung disease. Much to my suprise I got very ill with flu symptoms and also caused my mother to be ill with same symptoms. Now mindyou this was my first time ,my mother takes the seasonal shot every year. co-workers tell me I was already exposed before getting the shot. But my mother had her shot at least 1 month before I did. So was this a strain not in the seasonal shot or did it not work? I have not taken the seasonal flu shot since and have not been sick with the flu since. Here is my concern my job which is in a hospital is now making flu shots mandatory! Where is my right to choose? I listened and read all the information they provided,and there was a lot. Since I went more than 20 yrs. or more without the flu then take the shot and get very ill why should I be forced to take a shot in order to keep my job? have i lost my medical right to refuse treatment with informed consent?Being in the medical field I see more sideffects than I care to list,I also see doctors who dismiss pt,concerns sometimes until it too late . Doctors who are overloaded with patients and there is no way they can keep up with them. so why should I trust them with my health when I seem to know more drug interactions and sideffects than they do? Sorry after 38yrs and seeing a multitude of whoops I don,t jump every time they say take this drug it,s good for you.

    I know we are going to catch a lot of grief from my mom and 9 week old son's peditrician but my husband and I have decide none of us will get a flu shot. My husband and I have not recieved one in over 20 years and we have only gotten minor colds in that time. I am printing this article out to take to my son's peditrician at his appt today to show him my point. None of these vacvines had been properly tested.

    When I was pregnant with my son the hospital tried to force it on me but after reading many of the drs point of views on the vaccine in the health related newsetters my husband's Grandma recieves in the mail and I quote "the vaccines have not been properly tested over the 3 month span since swine flu surfaced on anyone especially pregnant women and children". I refused it and the triage nurse noted it in my chart, the dr threatened mr saying if I refused it my son would be taken from me at birth and placed in State care, yeah that didn't happen and never will happen, and I still to this day have refused the shot.

    Jenn – H1N1 is "the flu"! And whether the H1N1 vaccine is separate or part of the seasonal vaccine, it's just a flu vaccine and there's nothing special about it that makes it dangerous.

    Every year, the seasonal flu shot guards against the three strains the experts believe will cause the most problems, and those three change each year. This year, the H1N1 is one of those three.

    It just goes to show that the H1N1 vaccine is NO different that the regular vaccine and all the "controversy" was stirred up by people who didn't know what they were talking about.

    That's good news. I had both a regular flu shot and the H1N1 shot at the same time this year, and it made me feel funky for days. Hopefully the combined vaccine will be a little easier on those who get it than two separate shots.

    it's very suspicious to me all these vaccines there coming out with and insisting you take them, after reading the georgia guidestones I'm not taking any of the vaccines, a friend of my son's got the h1n1 vaccine and died 4 days later, people need to start questioning these vaccines instead of blindly following what the government tells you.

    I had the flu, it was annoying but now I have life time immunity, much better then taking life time toxins in my body. Vaccines are a crying shame and the fear tactics they use to manipulate the entire population into taking them is sad. Some are needed, but not all and their are side effects. Nor our the statistics widely published of how many people still contract a flu after the flu shot, or the statistics of negative side effects. I look forward to living a life without vaccines and my kids living that same healthy life.

    Believe what you see in your own community. Flu vaccines are not necessary and there have been NO sweeping waves of infection, death and destruction in your lifetime. A big marketing hoax wasting medical dollars and altering healthy immune systems. Mercury in every dose – protect your healthy brain by avoiding mercury exposure. That is more about health than media driven threats to sell unnecessary products every year.

    I'm not for the flu shot myself and have never had one, but many people here have misinformation. We need to be concerned for the right reasons.

    1) The virus strains included in the seasonal flu shot are not chosen at random. They are chosen based on predictions made by a lot of people with a lot of data. Some years they get it right, some years they guess wrong.

    2) H1N1 is in EVERY seasonal flu shot. There are 3 flu strains always included in the shot (one of which is H1N1) in addition to the predicted strains. Those of you saying you will stop getting the seasonal flu shot after years- no need. You've already been injected with H1N1 yearly.

    3) H1N1 is not new. This past season a novel (aka new) H1N1 *strain* was circulating, but H1N1 overall is nothing new.

    4) You will not "overload" on H1N1 if you receive the vaccine again. A good example of this is the seasonal flu shot with its same 3 viruses every year. Viruses enter the body all the time and we aren't always sick. In fact, only 1 in 10 cells in your body are yours- the rest are foreign.

    5) The seasonal flu shot is essentially a booster shot. Protective antibodies can wane over time if you are not continually exposed to a virus. An example of this is the CDC's childhood vaccination schedule. Childhood vaccines can and do stop working (assuming they ever work), some lasting 2 years or less. Because of this we have "booster" shots to "boost" antibodies to protective levels.

    Lastly, if you want more information, here is the CDC page explaining the process behind developing the seasonal flu vaccine:

    "Each year, the seasonal influenza vaccine contains three influenza viruses – one influenza A (H3N2) virus, one regular seasonal influenza A (H1N1) virus (not the 2009 H1N1 virus), and one influenza B virus. The influenza viruses in the seasonal flu vaccine are selected each year based on (surveillance-based) forecasts about what viruses are most likely to cause illness in the coming season. "
