According to the Centers for Disease Control and Prevention:

The flu vaccine protects against the three main flu strains that research indicates will cause the most illness during the flu season. This year's influenza vaccine contains three new influenza virus strains.

They are:

* A/California/7/2009 (H1N1)-like virus (the same strain as was used for 2009 H1N1 monovalent vaccines);

* A/Perth/16/2009 (H3N2)-like virus;

* B/Brisbane 60/2008-like antigens.

The 2010-11 influenza vaccine can protect you from getting sick from these three viruses, or it can make your illness milder if you get a related but different influenza virus strain.

The strain of H1N1 influenza included in the 2010-2011 seasonal flu vaccine in the US is the same that caused the H1N1 Pandemic "Swine" Flu in 2009. A separate vaccination for that will not be required this year.

Should you get the flu shot first or the Swine Flu shot?

In the US in the 2010-2011 flu season: The seasonal flu shot will include the vaccine for H1N1/09, so you won't need a separate shot for the swine flu this year, and you will get all the protection in one vaccination.In the 2009-2010 flu season:It doesn't matter which shot you get first, as far as being protected from both the seasonal flu and the swine flu is concerned, as long as you do get both types of vaccinations. The two vaccines can not be mixed in one shot. You can take both shots on the same day. As of the end of October, 2009 in the US, there is plenty of seasonal flu vaccine available, while the swine flu vaccine is still being reserved for those at highest risk until the production of the vaccine catches up with the demand. You should not wait to get the seasonal flu vaccine until the swine flu vaccine is available to your risk group in your location for best protection against the seasonal flu. Go ahead and get the seasonal flu shot as soon as you can, and then get the H1N1 (swine flu) shot as soon as it is available to you, too.The nasal mist vaccinations for the two types of flu can not be given at the same time. Live 2009 H1N1 vaccine (the type used in the nasal sprays) can be administered at the same visit as any other live or inactivated vaccine EXCEPT seasonal live attenuated influenza vaccine.

What would be the repercussions from giving a 4 month old child a seasonal flu vaccine?

he most likely will not get the flu

What strain of influenza is the seasonal flu?

Seasonal flu vaccines carry an H1N1 component, an H3N2 strain and an influenza B strain. The H1N1 component is not the Novel H1N1 strain that is in the swine flu vaccine

Local retailers are offering flu shots right now that they claim include the H1N1 strain while the CDC states that an H1N1 vaccine will not be available until mid October - what gives?

The seasonal flu shots for the 2009-2010 flu season in the Northern Hemisphere do not contain the vaccine for Pandemic A-H1N1/09 Swine Flu.To be fully protected from influenza this season, you will need to take the regular seasonal flu shot and then also another shot of the Pandemic A-H1N1/09 Swine Flu vaccine. Children will need two shots of the swine flu vaccine a month apart if they are under ten.As of today, September 16, 2009, the US Federal Drug Administration (FDA) is just finishing approvals for use of the new A-H1N1/09 Pandemic flu vaccine. It is not yet on the market, so if you are being told it is in the flu shot already out, then they are mistaken.There are different strains of the H1N1 virus and one of them is a typical and frequently seen seasonal flu strain. The 2009 - 2010 seasonal flu vaccine does contain a strain of H1N1 flu that is not the same as the A-H1N1/09 Pandemic swine flu. So it is likely that which has caused the confusion in this case.The seasonal flu vaccine for the 2009-2010 flu season contains the following strains of virus :A/Brisbane/59/2007(H1N1)-like virus;A/Brisbane/10/2007 (H3N2)-like virus;B/Brisbane 60/2008-like antigens.

How many doses of H1N1 flu vaccine does each state in the US have?

In the US and Northern Hemisphere in the 2011-2012 flu season, the H1N1/09 (swine flu) vaccine is included in the "regular" seasonal flu vaccination. There is currently (fall 2011) no shortage of this vaccine and no shortage is expected this year. The states are no longer holding and distributing swine flu vaccine and the seasonal flu vaccinations are back to being provided by various private pharmacies and other locations, such as a doctor's office. States are no longer storing H1N1 vaccines.

Can you have both a seasonal flu shot and a Swine Flu shot?

For the 2011-2012 flu season:In the US, there may still be some of the 2009-2010 season monovalent H1N1 vaccine, you could ask your health care professional and pharmacist if it will be available for you in the upcoming flu season. But, for the 2011-2012 flu season, it will be included as part of the trivalent seasonal flu shot and won't be separate like in 2009.According to the information from the Centers for Disease Control and Prevention about the 2011-2012 vaccine, the flu vaccine protects against the three main flu strains that research indicates will cause the most illness during the flu season. This year's influenza vaccine contains the following three influenza virus strains.The 2011--12 U.S. seasonal influenza vaccine virus strains are identical to those contained in the 2010--11 vaccine. These include A/California/7/2009 (H1N1)-like, A/Perth/16/2009 (H3N2)-like, and B/Brisbane/60/2008-like antigens. The influenza A (H1N1) vaccine virus strain is derived from a 2009 pandemic influenza A (H1N1) virusThe strain of H1N1 influenza listed above that is included in the 2011-2012 seasonal flu vaccine in the US, is the same that caused the H1N1 Pandemic "Swine" Flu in 2009. A separate vaccination for that will not be required and if you had it before, it will not hurt to get it again and might help.

Can you get the H1N1 vaccine without the seasonal flu vaccine?

For the 2010 - 2011 Flu Season:The seasonal flu vaccine for the upcoming season will contain the H1N1 pandemic flu virus, so this year you will only need to get one vaccination to cover H1N1 and the other two seasonal flu strains chosen for the vaccine for this season. There may still be some of the 2009 - 2010 season monovalent vaccine for H1N1 available if you can not take the seasonal flu trivalent vaccine for some reason, you will need to check with a pharmacist where flu shots are being provided or with your health care professional to find out if that will be possible this year.For the 2009 - 2010 Flu Season:Yes, you could. The A-H1N1/09 and seasonal flu are two different diseases. It is recommended that you do get both vaccinations in the 2009-2010 flu season in the Northern Hemisphere. You get them in two different shots, but you can get them at the same time or at different times. There are also nasal mists. You can not get the two different nasal mists at the same time but you can get one vaccine by shot and the other by nasal spray at the same time or you can get both shots at the same time. If you have already had one or the other vaccines, then you can just get the other when it is available to you.

Is it safe for your child to get the H1N1 vaccine between his 1st and 2nd dose of the seasonal flu vaccine?

Yes, if they are getting both vaccines by injections. That timing of the two kinds of vaccinations (seasonal flu shot and swine flu shot) is not a problem, in fact they could be given at the same time. This is not true for the nasal mist vaccinations, however.You can NOT take a nasal flu mist for swine flu at the same time as you take a nasal flu mist for seasonal flu. They can render each other ineffective. Ask a health care professional how long you should wait between these two kinds of nasal mist vaccinations.You can take a nasal flu mist for swine flu with any other nasal flu mist vaccine EXCEPT the one for seasonal flu.The 2009 H1N1 flu shot (inactivated 2009 H1N1 vaccine) can be given at the same visit as any other vaccine, including pneumococcal polysaccharide vaccine.You can take a swine flu nasal mist at the same time as a seasonal flu shot.You can take the H1N1/09 swine flu shot and a nasal mist for the seasonal flu at the same time.There would be no reason to take the swine flu shot at the same time as the swine flu nasal mist since both do the same thing, so that should not be done.

Can you get more than one flu vaccine a year?

Usually you only need a single vaccination each flu season since the seasonal flu vaccination contains vaccine against the three mostly likely types of flu to be circulating during that season. In the pandemic of H1N1 in 2009, two vaccinations were needed, one for the three types of seasonal flu and one for H1N1/09 "swine flu." In the 2010-2011 flu season, the H1N1 vaccine is included with two other flu virus vaccines to make up the seasonal flu vaccination. If you had the swine flu vaccine in 2009, it won't hurt to have it again in the seasonal flu vaccination. If another new flu virus is found to have developed, then, like in the 2009 pandemic, vaccines for the new flu virus may be produced in time to be taken, but not in time to be included in the seasonal flu shot as one of the three virus vaccines. Then, a second vaccination for the new flu may be required as it was in the 2009 - 2010 flu season of the pandemic. Other than the potential sore arm, it won't hurt to have flu vaccines more than once for most people. Ask a doctor, pharmacist, or the clinician delivering the vaccination for advice before the vaccine is given.

How many different virus strains does the 2013-2014 seasonal live attenuated influenza vaccine have?

Typically the flu vaccine is trivalent, with three strains.

How long does immunization against Swine Flu last I was inoculated last year does it cover this year also?

Immunization from a vaccination or from having had that exact type of flu will give you lifetime immunity. However, because viruses tend to mutate into other kinds of flu, your body may not recognize the germs as the same and then you would need protection from the new mutated virus, too. The 2010-2011 seasonal flu vaccination in the US contains the H1N1/09 vaccine along with vaccine for two other kinds of flu. If you had the swine flu vaccine last season, then it will not hurt you to take the vaccine again when you get the seasonal flu vaccination and it might help.

Is the Swine Flu vaccine effective against the regular flu?

Each flu vaccine is targeted to specific varieties of the flu virus. Unless another type of flu is very similar to the targeted virus, it will not be prevented with that vaccine. Having said that, since the 2010-2011 flu season through to the current 2011-2012 season, the "regular" seasonal flu vaccine, which always contains three types of flu vaccine (trivalent), has included the swine flu along with the other two varieties to which the vaccine was targeted. So in that sense, at least currently, the swine flu vaccination is effective against the regular flu since vaccines for each type are put together in one vaccination.
