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

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
How effective is the flu shot for this years flu season? When can we expect the flu season to die down/be over?
About 60%: reduction in doctor visits for Influenza Like Illness. The H3N2 virus predominant this year is antigenically different than the one in the vaccine. The last time this happened was in 2007-8 and vaccine effectiveness was 43% then. Usually activity drops off about Week 13 which is usually the end of March. Thanks for trusting HealthTap! ...Read more
Define effective: The flu strains mutate often. Each year the predominant strains change. The flu vaccine is developed yearly using 3 strains that are circulating and already causing flu in so many places that a they are expected to continue.The vaccine stimulate production of antibodies to the included strains that last for years. However, the flu mutates so often, the benefit can be limited to one season. ...Read more
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

Possibly fatal: Rabies is fatal. If you get it, you will die. There is little to know treatment. Once you have been exposed, you have a about 6 weeks before you get the disease. It takes time for the vaccine to work, maybe longer than 6 weeks. You need the instant protection of the Immune Globulin shot to give the vaccine time to work. ...Read more
Mid-Sep. to mid-Nov.: In the U.S., the best time to get a flu shot each fall is in October, which means September through November is fine. However, if one misses his shot at those times, it is still fine to get it anytime until the end of the flu season. The flu season ends at the end of winter (February-March). ...Read moreSee 1 more doctor answer
Side effects and...: Flu shots often cause side effects like muscle/ joint aches, fever,headaches,fatigue and irritability and rarely Guillan-Barre syndrome which causes paralysis (see https://www.drugs.com/pro/fluarix.html). While you can't get flu directly from it,flu shots appear to lower immunity to other viruses including 4.4x risk of viruses that cause sinusitis,colds and bronchitis! https://tinyurl.com/jjmqtvp ...Read moreSee 1 more doctor answer
3 influenza strains.: If you're asking about which strains, it contains the following 3 influenza strains for the 2011/2012 season: •a/california/7/2009 (h1n1)-like (same strain as was used for 2009 h1n1 monovalent vaccines) •a/perth/16/2009 (h3n2)-like •b/brisbane/60/2008-like. ...Read moreSee 1 more doctor answer
Same symptoms: The flu shot protects people about 85% of the time and mitigates the symptoms and complications so they would not be as severe as when there is no flu shot. There will still be body aches, fever, headache and some upper respiratory symptoms or even stomach symptoms but to a lesser intensity, that's relative as that is a measure in that specific person. ...Read more
Oops!: I assume this was an error. Injectable flu vaccine is a killed virus vaccine. Your baby will not get the flu from it. Because there is more antigen in the adult form of vaccine your baby may have more antibody response--fever, aches, fussiness. If your baby got a multidose vial flu it was likely preserved with some thimerosol. This has a little mercury in it. I would talk to the dr about that. ...Read more
Not necessarily: Influenza vaccine may or may not cover each of the influenza viruses currently circulating in the community, and some people do not necessarily develop complete immunity to the strains contained within the vaccine. If you know that an individual with whom you are going to be in contact has influenza and you can avoid contact that would be the safest course of action. ...Read moreSee 1 more doctor answer
