Why Every year a new influenza vaccine is developed What is the most likely reason that doctors do not use the same vaccine each year?

Typically the flu vaccine is trying to predict the possible states of the flu coming for that season. The flu virus mutates so rapidly that they are always trying to predict what's coming next. That's why you can also still get the flu even if you get a flu shot.
STUDY ISLAND ANSWER:The virus which causes influenza adapts each year to the last vaccine in order to survive and reproduce.

What are the risks for not taking vaccines?
Every vaccine is designed to protect against some infectious disease. If you do not take the vaccine, you are more likely to become infected by that disease. If you do not get the polio vaccine, you are more likely to get polio, for example.
Is the influenza vaccine the same as the flu injection?
More or less. The flu and influenza mean the same thing. Flu is just a shortened version of the word. The flu vaccine is sometimes given by injection into a muscle. The flu injection, flu shot, flu vaccination, influenza injection, influenza shot and influenza vaccination are all talking about the same thing. The only differentiating part is that when you say influenza vaccine, you may be referring to the vaccine that is given in the form of an intra-nasal mist or spray and not in the form of a shot. Both forms are available for flu vaccines. The vaccine is the medicine in the flu shot (flu vaccination, or flu injection). Flu = Influenza Vaccine = Medicine in a vaccination Vaccination = Introduction of infectious agent (vaccine) for immunity = Giving a dose of a vaccine (can be oral, injected, or nasal administration) for the purpose of immunization/prevention of infection Immunization = Vaccination = Infection preventative Immunity = Immunized = Not susceptible to Shot = Injection Vaccination methods = shots, mists, tines, scrapings, oral vaccines
What if you get chickenpox after having the vaccine?
If you get chickenpox after having the vaccine, it is likely to be very mild case and unlikely to cause serious complications.
How is an influenza virus most likely to enter your body?
Through your nose or throat.
Which substances would most likely be contained in a new vaccine developed against a newly found viral infection that appears in a population?
The weakened form of the virus or parts of inactivated virus strains to which the immunity from the vaccine is desired. There will also be other ingredients that preserve and prepare the compound for administration. See related question below.
What does the triple antigen vaccine prevent?
There are different kinds of triple antigen vaccines. A triple antigen vaccine is one made with three different antigens (often three virus strains). The seasonal flu vaccines are examples of triple antigen vaccines, because they contain vaccines against the three influenza viruses most prominent and most likely to spread that season. These are also called Triple Valent or Trivalent vaccines. Another example is the MMR trivalent vaccine made to vaccinate against Measles, Mumps, and Rubella. Several of the childhood vaccinations are this type of trivalent vaccine.
Why do we have to get a diffrent flu vaccine every year?
The influenza virus is in a continuous state of mutation. Each year different strains become prominent. If the educated guesses of the disease control folks are accurate, they can produce a vaccine that will be aligned with the proteins on all of the most common strains for a given year. Occasionally they get it wrong and the vaccine is only effective against a fraction of the most common strains. Because the strains are different from year to year, the previous year's vaccination is not very likely to provide immunity for the currently most common strains.
When was the H1N1 shot made?
There have been several versions of H1N1 influenza over the years. But the most recent H1N1 flu was the pandemic "Swine Flu" A-H1N1/09. The monovalent (made with and for protection against a single virus) vaccine for it was made just before the flu season in fall/winter 2009-2010. Again, in the 2010-2011 flu season the same vaccine was included in the trivalent (made with three viruses) vaccine for the seasonal flu. If you had the monovalent vaccine in 2009, then you should still take the trivalent vaccine for the 2010 flu season. It will not hurt to get another dose of the H1N1/09 virus vaccine, it might enhance the immunity of some people, and you need to be vaccinated for the other two viruses that are most likely to be going around in this season.
Are you protected if expired flu vaccine was used?
Probably not. Each year the ingredients in the flu vaccine are different, because each year different strains of the influenza virus are going around. They have to make up a new vaccine each year, to be sure it contains all the right strains that will provide immunity for the kinds of flu that are circulating at that time. Since the vaccine for the seasonal flu for this year in the Northern Hemisphere has just been manufactured and released very recently, it would not seem possible for it to be already expired. If you use a vaccine from a prior year (the more likely scenario if the expiration date on the bottle has already passed), then you will not be fully protected against the strains of virus that will be causing flu this year and may be taking something that could be harmful in addition to providing no protection. You should talk to those at the source of the vaccine to find out why the vaccine would be expired.
How can an epidemic be controlled?
Flu Shots, other than that you could try the last option, but for most of us it is completely excessive.Maybe you have a really bad immune system:Quarantine yourself1) Live in a airtight room that filters all air that comes to youThe less human contact (direct contact) the better (you can still socialize, have visitors, and physical contact so long as your visitors wear air tight suits that prevent anything from getting into your sterile room). Have your room cleaned regularly.2) All food must be treated before you consume it, and sent to you in a special canister All food must be irradiated or cooked in an oven at high heat, UV light on drinks before you eat it as a precaution.3) Make sure you are very sanitary in all bathroom activities.
How does the influenza virus stimulates the body?
most likely enters through nose,mouth or eyes.
Can the hpv vaccine delay your period?
No, the HPV vaccine shouldn't delay your period - in some rare cases it's been said that HPV has effected womens fertility, but there is no confirmation of this. It's most likely that if you're getting the HPV vaccine you're in your teens so irregular cycles are normal at your age, it's likely got absolutely nothing at all to do with your getting the HPV vaccine.
