Why do I have to get a flu shot every year when other vaccines I can just get once?

Why do I have to get a flu shot every year when other vaccines I can just get once?

Flu changes: The influenza virus mutates as it travels around the world each year. It arrives back changed enough that our immune system does not recognize it from the last round (or shot) this means we have to get vaccinated each year for the new "strains" of flu since our body perceives it as a new virus. Some years the virus changes more than others, leading to worse epidemics if the shot is rigged wrong. ...Read more

Flu Shot (Definition)

Also known as influenza vaccines, flu shots are given out once a year to protect against the flu. The flu shot stimulates the immune system to build antibodies to three or four strains of flu viruses in the hopes that it will offer protection from the current strains present in the community. Each year the Centers for Disease Control (CDC) monitors the strains of Influenza globally and incorporates the appropriate antigens in the new vaccine. For best protection the vaccine ...Read more

I'm 100% up to date with all vaccines other than flu shot. Are their any vaccines I must have repeated or do most last a lifetime?

I'm 100% up to date with all vaccines other than flu shot. Are their any vaccines I must have repeated or do most last a lifetime?

Depends: Some vaccines provide time limited benefit (whooping cough, tetanus, diphtheria, meningitis, flu) while others may last a lifetime (hepatitis B series, measles, HPV series). Some of the newer vaccines have not been used long enough to know if their benefit is lifetime or a booster is needed. All adults should review their vaccine status with their doc at their regular checkups. ...Read more

What exactly makes up a flu shot vaccine?

What exactly makes up a flu shot vaccine?

Not live...: The flu vaccine does not have any live flu virus. Rather, it consists of killed virus or protein from the virus. Your immune system then reacts against the virus protein and makes antibodies so that if your body then is exposed to the actual virus, the antibodies needed to kill it are already there. This prevents you from getting sick from the virus since the antibodies kill it first! ...Read more

My baby isn't up to date on vaccines, can she still get a flu shot?

Why are vaccines more painful than a normal yearly shot like the flu shot?

Why are vaccines more painful than a normal yearly shot like the flu shot?

I'm not sure what: Vaccines you are referring to. One vaccine that patients often say hurts more than the others is Gardasil. The Flu vaccine actually does often cause pain, as does a tetanus vaccine. The soreness is from the body's immune response to the vaccine, which means it is starting to work. Some of the pain is also from the needlestick, itself, especially those vaccines which go into the muscle. ...Read more

If flu shot vaccines are created from last year's flu, how can it protect against a different stem of the flu?

If flu shot vaccines are created from last year's flu, how can it protect against a different stem of the flu?

There are 3 strains: Every year a bunch of experts meet and decide what strains to put in the flu vaccine for the next season. They usually put in 3 different types, almost always one from the preceding year, and then two others that they decide on based on many factors. There is talk that they may start trying to use 5 strains in the next few years. Anyway, you should get a flu shot every year! ...Read more

With activated vaccine can you get flu from flu shot?

With activated vaccine can you get flu from flu shot?

Nasal vs injected: What you mean by activated is unclear. There is no activated vaccine I am aware of. The injected vaccine is prepared from inactivated (killed) virus & cannot give you the flu. You can develop a shot reaction (mild) but it is not the flu. The nasal mist is a much weakened but live virus & rarely causes a mild flu like illness, but far less intense than a regular flu would be. ...Read more

3yo child has low neutrophils (and other low counts). Been instructed to continue to defer live vaccines. Can she still get her flu shot?

Could I be allergic to just dippy-cooked eggs? It seems like I can eat scrambled and hard-boiled eggs. What's it mean for vaccines like the flu shot?

Could I be allergic to just dippy-cooked eggs? It seems like I can eat scrambled and hard-boiled eggs. What's it mean for vaccines like the flu shot?

Yes: Some egg allergic individuals are able to tolerate well cooked or baked egg, but have issues with under cooked or raw egg. There is no specific recommendations on how well to cook eggs, and care needs to be taken. I would recommend evaluation by a board certified allergist. For the Flu shot- The amount of allergen in the vaccine in minimal, unless you reacted in the past get the vaccine ...Read more

Besides the seasonal flu shot and h1n1 vaccine, are there any other shots I should get?

Several possible: For an otherwise healthy 33 year old person, you should make sure you have had a tdap and I would recommend the hepatitis b and hepatitis a vaccine series. If you have never had the chickenpox you should be vaccinated for that as well. Some other vaccines may be indicated based on a person's medical history. ...Read more

I have never had a flu shot get the flu once a year. Are these super flus bring created by your vaccine eventually gonna get me and prob devour me?

I have never had a flu shot get the flu once a year. Are these super flus bring created by your vaccine eventually gonna get me and prob devour me?

Odd question: There are no "super flu bugs" created by vaccines. Vaccines are derived from strains created in nature. Nature sometimes mutates a flu strain to such a degree that a major part of the world population has never had a similar flu and it may reek havoc, as it did near the end of WWI. Since you get the flu every year, you likely have some partial immunity to new strains and don't get it as bad as some ...Read more

How good are the preservative free flu vaccine? And what's the difference from the regular flu shot?

How good are the preservative free flu vaccine? And what's the difference from the regular flu shot?

Any flu shot better: Than none. Thimerosal is preservative used in multi-dose vials of flu vaccines while single-dose vials are preservative free. Other than that, there is no difference between the actual active flu shot. The preservative is used to prevent contamination when a multi-dose vial is punctured several times. Check out http://www. Mayoclinic. Com/health/complex-regional-pain-syndrome/ds00265 for more info. ...Read more

Can someone tell me if the h1n1 (swine flu) vaccine is the only flu shot available now?

Can someone tell me if the h1n1 (swine flu) vaccine is the only flu shot available now?

Confusing question: The h1n1 is one of three or four strains in the flu vaccine prepared for the 2013-2014 season. It is also the predominant strain responsible for most serious cases of flu this year. The single strain h1n1 flu vaccine was only produces during the 2009 season when the strain emerged in the preseason (april) but was not in the regular vaccine produced that year. ...Read more

Pain in top leg when walking, had flu shot last Thursday is it connected? Could be beginning of guillian barre syndrome caused by vaccine?

Pain in top leg when walking, had flu shot last Thursday is it connected? Could be beginning of guillian barre syndrome caused by vaccine?

No: Guillian barre doesn't cause pain, & what minor sensory symptoms it causes usually occur where weakness begins (almost always in the feet). You've posted before. You weren't joking when you put "hypochondria" in your profile. Reminds me of the old Michael Palin BBC series "Ripping Yarns." In the episode "The Curse of the Claw, " the character Uncle Jack had "every known disease." ...Read more

18 month old got her vaccines that were due and a flu shot 10 days ago. Now she is breaking out in hives. No symptoms or diet change. Related?

Possible: It is usually not the killed virus itself but what may be added to the vaccine which can cause an allergic reaction. For example, some vaccines do contain small amount of gelatin to which a few people may have become allergic. ...Read more

You are also protecting people around you, especially infants and the elderly from those same strains. ...Read more

Any side effect for getting a flu shot and a pneumonia vaccine every year?

Immunizations: Annual flu shot good idea: may feel achy few days while body builds defenses against flu viruses. Pneumonia vaccine generally not given every year unless immune system is compromised. Originally was given one time; now may be given more than once in elderly who don't mount as strong an immune response. Both can cause localized soreness at injection site. Rare possibility of guillain-barré syndrome. ...Read more

Sick after getting flu and meningitis vaccines? Around 5pm yesterady, I got a flu shot and a meningitis shot. I didn't feel sick at all until this morning when I woke up with a huge headache and just feeling sick in general. Last night after getting the v

Yes: After getting a vaccine, specifically the flu vaccine, a person can certainly have some flu-like symptoms. If your symptoms are severe, you may want to get checked out by your doctor. If tolerable, you can treat it like you would the flu: bed rest, fluids, tylenol, (acetaminophen) etc. ...Read more
