Why did my daughter get sick after getting the flu vaccine?

Why did my daughter get sick after getting the flu vaccine?

Mild rxn can occur.: Flu shot side effects may include: slight swelling, redness or pain at vaccination site. If headache, nausea, fever or muscular pain occur they usually resolve within one to two days. You won't get the flu from a flu shot because the virus either contains inactivated virus or doesn't have virus particles in it. Severe side effects are rare. ...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

Can a child vomit after getting the flu vaccine shot?

Can a child vomit after getting the flu vaccine shot?

Yes: People who are sensitive to vaccines or the adjuvants in them can react and vomiting is a possibility. It is more likely to be associated with the vaccine reaction if it occurs right after or within 24 hours in my experience. Some people experience fever, fatigue, irritability, or just not feeling well after vaccines. ...Read more

What are the negatives, if any, of getting the flu vaccine?

What are the negatives, if any, of getting the flu vaccine?

Hardly any: Flu vaccine is very safe. Vast majority of people will have nothing worse than a slightly sore upper arm. Even if you get the flu later in the season it's likely to be mild. It's recommended for nearly everyone. Pregnant women are strongly encouraged to get the flu shot because they are more susceptible to complications including death. People who have chronic conditions should get it too. ...Read more

What are possible side effects of getting the flu vaccine twice?

No Risk, No Benefit: You may have localized swelling and pain at the injection site if you take a Flu shot twice, and I am sure your wallet will feel the loss of the co-pay for two shots -otherwise, you will be fine. Is there any particular reason you wish to take the Flu shot twice? Studies have not shown that additional doses within a 6 month period are helpful. Talk to your Doctor about your concerns. ...Read more

Does getting the flu vaccine help prevent getting the flu during flu season?

Yes, but...: Note also that "flu vaccine" specifically covers influenza virus (and only targeted strains at that), where as people often refer to the "flu" during "flu season" as any viral illness (there are lots of other viruses which can cause fever and other symptoms besides influenza!). This is a large contributor to the misconception that someone's annual flu vaccine "didn't work". ...Read more

Hypochondriac-deathly afraid of flu. Heard so much paranoia and fear tactics used against getting the flu vaccine. What's the truth, is it safe?

Hypochondriac-deathly afraid of flu. Heard so much paranoia and fear tactics used against getting the flu vaccine. What's the truth, is it safe?

Asked and answered: Didn't you just ask this question? The flu is a debilitating illness of fever, chills, muscle aches and pains. Depending upon the strain young people such as yourself are hit especially hard. One recent winter a disproportionate number of deaths were in young people. It can progress to a severe pneumonia. Side effects are mild. Serious side effects very rare. Fear the flu, not the shot. ...Read more

Flu like symptoms after flu vaccine. Is this contagious?

Depends: If you had the nasal product this is a living virus and you could pass the "vaccine strain" to others. This might produce mild or no symptoms if passed. There is no way that you get or pass the injectable flu vaccine. It is a dead virus. If you had symptoms it is due to a reaction to getting the vaccine, not a flu. ...Read more

I've been getting very severe joint pain after getting the flu shot. I can't even move things sometimes. I get to the point of crying. Extremely painful.?

Can happen!: It is uncommon, but painful joints and arthritis sx can occur after a flu shot. Bear with it, because it is short lived. Low dose Prednisone (2.5-5mg) and nsaids should really improve your sx. Please do not less this "bad" experience keep you from getting vaccinated in the future. ...Read more

Can you get the flu after getting the flu shot in janurary. I had flu symptoms like normal but they stopped a few days later.

Can you get the flu after getting the flu shot in janurary. I had flu symptoms like normal but they stopped a few days later.

Influenza: The vaccine is not 100% effective, even when you are encountering the same strain contained in it. Flu-like symptoms may not be due to influenza, but to one of several other viruses. So your answer is yes. You can get both influenza and influenza look-a-likes after receiving the vaccine. You can also get a modulated illness with the strain contained in the vaccine. ...Read more

Does getting the flu shot increase herd immunity? Should young, healthy people get it? I thought it was supposed to be for young children, pregnant women, and elderly people...? The "at-risk" population?

Does getting the flu shot increase herd immunity? Should young, healthy people get it? I thought it was supposed to be for young children, pregnant women, and elderly people...? The "at-risk" population?

Flu shot: Everyone should get an annual flu shot. Herd immunity increases the more people are vaccinated. This prevents diseases from spreading. While pregnant women, infants and the elderly are at higher risk of death from flu no one can be certain they won’t be a victim. Protect your self and others by getting vaccinated. ...Read more

Had flu shot in mid november -- tested positive for influenza a after a very mild illness. How did I get the flu? Am 22 weeks pregnant.

Aprox 80% effective: First the flu shot takes 3 weeks to build full immunity so next year take it late october this way when the season starts (nov in the ne) you are ready. Influenza affects about 20% of the population an the vaccine gives about 80% immunity if correctly paired to the current strain. In your case you did get flu but had some immunity since it was mild. Stay hydrated! ...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

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

Is the flu vaccine not working? I know drs urge it but if it doesn't work don't want to get it.

Is the flu vaccine not working? I know drs urge it but if it doesn't work don't want to get it.

The trouble with flu: Yearly, we have at least 6 flu strains circulating the globe. The drug makers use surveillance data to pick the 3-4 top strains in March, and rush to put that into a vaccine. More strains would weaken the protection provided by the vaccine to those strains included. By the fall/winter, newer strains can develop and air travel brings them to you. The vaccine helps, but cannot stop all flus. ...Read more

Is there any particular time of year to get flu vaccine or can be taken any time? Also does it protect for whole year? Mean when to repeat?

Is there any particular time of year to get flu vaccine or can be taken any time? Also does it protect for whole year? Mean when to repeat?

As soon as available: The flu vaccine will generally protect against 3-4 strains of flu. That protection is good for at least a year and likely several, but only against the strains included in the vaccine. The flu mutates often, and every year 5+ strains circle the globe, so effectiveness of a given shot varies year to year, but must be given yearly to keep up with mutated strains. ...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?

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

Can I get the flu from the flu vaccine?

No!: No, the flu shot is a dead vaccination and not able to pass infection. There is no live virus there to cause infection and therefore zero percent chance of this occuring. The nasal flu vaccine, on the other hand, is a live virus vaccine. However, it is engineered to die at body temperature and therefore not able to cause significant illness. It may cause runny nose and congestion but not full flu. ...Read more
