Confusing question: The flu vaccine is composed of purified, non-living material that represents the common flu strains for the year. The immediate effect is transient injection pain followed by soreness in the muscle for a day or less. There is a trace amount of egg protein which limits its use for those with significant egg allergy.For others, the vaccine is quite safe and effective.
I have had pneumonia four times the last two times were within last two years. I'm getting a flu shot this year do I need a pneumonia immunization too?
Shot: Yes it is to your benefit to get the pneumonia shot.
The viruses are: Constantly mutating. Studies are done to see which strains are most likely to be problematic each year.
Differs with vaccine: The injectible flu vaccine is a dead & does not give anyone the flu but some may have a mild reaction to the vaccine. The body develops antibodies to the dead flu "bodies" just as if they were alive, protecting you from flu. The living nasal mist is a weakened live flu preparation that can give some mild flu sx, but you develop protective antibodies without developing full blown flu disease.
Been sick for 10 days. Been to Dr they say influenza but didn't do swab. Not getting better. Could I die from flu? Had vaccine. Read about death myage
Likely not influenza: Hi - given your symptoms influenza is not likely unless you have other symptoms besides the ones listed above. Flu symptoms include cough, fever, chills; also commonly muscle aches especially in the legs. Your lack of respiratory symptoms makes me worry about another virus OR another illness entirely. Very few healthy adults die from flu.
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!
Depends: For an average healthy person, either injectable quadrivalent flu vaccine or inhaled quadrivalent flu vaccine would be reasonable choices. But if there is an egg allergy, any immune problems, or certain other complicating factors, that would impact which vaccine is used. This should be discussed between you and your doctor.
Flu shots are GOOD.: 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.See 1 more doctor answer
Which one?: The general label "swine flu" has been applied to several strains of flu. A vaccine was developed to the H1N1 that circulated in 2009, and included in several seasonal flu shots since that time. Since other strains have also carried this non-specific label, you need to be more specific for a firm answer.
Not specificly: Although the polio vaccine & the rotovirus vaccine cover two germs that cause a diarrheal illness, there is none for the broad range of enteroviruses that cause the stomach flu.
See below: Normal healthy individual with intact immune system does not get infected by vaccine strain which is attenuated. If you are known to be immunocompromized, you may need to see infectious disease specialist.
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.
Yes: Not everybody develops an adequate immune response to the vaccine, you may be infected with a different strain of virus than the one contained in the vaccine, or you may have an influenzal-like illness which is unrelated to the virus.
Sure: Vaccines are rarely 100% effective, and sometimes the flu strain in circulation isn't the one that was predicted.
