Will getting the flu shot help prevent pneumonia?
Not directly. The flu shot will only prevent the specific type of viral influenza that the vaccine has been developed to prevent. Most pneumonia is due to bacterial infections and not viral, although viral pneumonia and bacterial pneumonia are both common secondary complications of influenza. So, in the sense of preventing the flu that might have a secondary complication of pneumonia, it could be somewhat effective but not assured. For better prevention of pneumonia, there is a pneumonia vaccine that can be received at the same time as the flu vaccine, which is often done in the elderly or those with underlying health problems, especially chronic lung or heart diseases.

No, the flu shot will only be effective to provide immunity to the specific flu viruses in the vaccine.
Very little chance of getting the flu in spite of getting a flu shot. Perhaps 10%, probably less, of the people who get the flu vaccination end up getting the flu anyway. In m…ost cases these people have a problem that affects their immune systems and doesn't allow them to achieve a full immune response that is needed for immunity. Studies have shown reductions in flu by up to 90% from the effective use of flu vaccinations. It is safer to get the vaccine than to risk going without it. You needn't worry about getting the flu from the shot. Flu vaccines are made in two forms, either from deactivated ("dead") viruses, or from "attenuated" viruses, which have been processed so that they can not make you sick. Attenuated means weakened. In the US flu vaccines come in both forms. The attenuated versions are administered in nasal sprays and the inert vaccines are prepared for injections into the muscle. See the related questions below for more details.
Wash your hands.
If you actually get the flu, and not just a mild reaction to the vaccine (which can seem similar at first), it will most likely be because you: had it already before you got …the vaccine and just had not shown symptoms yet; or,between the time you took the vaccination and your body developed the full immunity you caught the flu (this can take as long as two weeks, but with the 2009 H1N1 vaccine it worked as quickly as 8 - 10 days in some people); or,you may have caught a strain of flu that was not included in the vaccine, and so the vaccination would not provide immunity to it (however, if a similar strain, it could make your symptoms milder). Also, the ability of flu vaccines to protect a person depends on: the age and health status of the person getting vaccinated, andthe similarity or "match" between the virus strains in the vaccine and those circulating in the community.
Yes, it does again in the US in the 2012-2013 flu season as it did in the prior flu season. See the related questions section for more information about the vaccines in 201…2-2013 flu season. 2012-2013 For the 2011-2012 flu season in the US, the Food and Drug Administration (FDA) announced the approval of six vaccines on July 18, 2011. These approved trivalent vaccines for the seasonal flu will all contain vaccine for the H1N1/09 "Swine Flu" and two other viruses suggested by CDC for this season (see more below). These approved vaccines are: 1. Afluria (CSL Limited) 2. Fluarix (Glaxo Smith Kline Biologicals) 3. FluLaval (ID Biomedical Corporation) 4. FluMist (MedImmune Vaccines, Inc.) 5. Fluvirin (Novartis Vaccines and Diagnostics Limited) 6. Fluzone, Fluzone High-Dose, Fluzone Intradermal (Sanofi Pasteur, Inc.) The Fluzone Intradermal is a new formulation for administration in the layers of the skin (intradermal injection) instead of the intramuscular (IM) injection. Fluzone Intradermal administration uses a microinjection system with a very fine needle. Approved for those aged 18 through 64. The CDC-approved trivalent vaccines for the 2011-2012 flu season will protect against the following three virus strains: 1. A/California/7/09 (H1N1)-like virus (Pandemic (H1N1) 2009 influenza virus) 2. A/Perth/16/2009/ (H3N2)-like virus 3. B/Brisbane/60/2008-like virus Nomenclature The naming convention for virus strains such as the one used to produce the pandemic A-H1N1/09 vaccine [ A/California/7/2009 (H1N1)v-like virus ] is explained below: A/California/7/2009 (H1N1)-like virus A = Type A influenza. There are three types of influenza: A, B, and C. CALIFORNIA = The location the strain was first identified. 7 = The strain identification number. 2009 = The year the strain was identified. H1N1 = The antigenic characterization of the H and N proteins. [Antigenic characterization is a method used to describe influenza proteins neuraminidase (N) and hemagglutinnin (H) and how they have changed.] Historical information about the H1N1/09 vaccines: 2010-2011 Flu Season In the US for the 2010-2011 flu season, the vaccine for H1N1/09 is included in the "standard" seasonal flu vaccination. The seasonal flu vaccine is made each year with three types of flu virus vaccines in it. This year one of the three vaccines in the seasonal flu vaccination is the H1N1/09 vaccine. So only one flu vaccination is required to be protected from Swine Flu and from the other two flu viruses that have been determined to be the most likely to be circulating in the Northern Hemisphere during this flu season. If you got the swine flu vaccination last year, it will not hurt you to get the vaccine for swine flu again. If you had the swine flu, then it also won't hurt to get the vaccine now. In fact, unless you had specific lab testing to confirm the exact strain of flu virus that made you ill, you will be sure you have full immunization to A-H1N1/09 by getting the seasonal flu shot, just in case you had a different kind of flu than you thought. The best way to prevent the flu is immunization. 2009-2010 Flu Season The US Food and Drug Administration (FDA) approved four types of A-H1N1-09 ( Swine Flu) vaccines for use in the US in 2009 - 2010. Three of these were injectible vaccines and one was a nasal spray for certain age groups to use. The distribution for use was begun with the first batch on 10/6/09. The vaccine that was new in 2009 was made specific to the A-H1N1/09 virus only, that is why in 2009-2010 flu season there was a need for two vaccinations for the flu. It was initially provided first to those at highest risk until enough vaccine was produced to keep up with the demand. It was being made available free of charge in the US to any one who wanted to use it (although some private providers, such as doctors or pharmacies, may have charged a fee for administering it). There were public immunization programs set up at clinics, schools, hospitals, and other locations under the direction of the public health authorities in each state, who were also in charge of the distribution of the vaccine supply. Anti-viral Treatment of H1N1: If caught early, the Swine flu may respond to treatment with two of the anti-viral medications that have been designed for animal strains of flu, oseltamivir and zanamivir. These medicines do not work to prevent or to cure or "kill" the viruses, they work to shorten the duration of the infection and to ease the severity of the symptoms once you already have it. Antibiotics are for killing bacteria, they do not work on infections by viruses which is why they are not prescribed for directly treating the flu or other viral infections. Prevention: See the related question in the section below for additional information about protecting yourself from contracting viruses. The most important step is basic hand washing and hygiene as described in the related question. There also have been studies showing that taking certain vitamins, such as Vitamin C, can help build a stronger immune system for fighting viruses and other microbes. Prevention is the best medicine! Get a vaccination! Additional information: More information from the US Centers for Disease Control and Prevention (CDC) is accessible via the related link in the section below.
You will feel a little sharp poke and sting with the intramuscular (IM) flu vaccine. Afterward it might get a little sore at the site of the injection. It's much better than g…etting the FLU, though. There is now a new form of flu vaccines (called Fluzone ID in the US) available for the 2011-2012 flu season that uses a "Microinjection system" to inject the vaccine between the layers of skin. This new type provides: Improved acceptance by needle-averse individualsNeedle is not readily visible to the patientNeedle size 90% smaller than IM needles, 30 gaugeNeedle depth 1.5 mmSmaller amount of vaccine solution injected 0.1 mL Less antigen per injection, 27 mcg compared to 45 mcg IMTrials indicate less pain with injectionsCan cause more local injection site symptoms of mild to moderate redness, swelling, and other site reactions than IM, for 3-7 days than IM Fewer systemic reactions (fever, headaches, muscle aches, etc.) than IM 75% of trial participants were very satisfied96% of clinicians giving the ID vaccines would recommend that method

No, but if you get swine flu and regular flu shot, it will be harder to get the flu.
The trivalent flu vaccines prevent infections by the three types of influenza that scientists and epidemiologists have determined through studies will be the most likely to be… circulating during the upcoming flu season. For the 2011-2012 Flu season in the US and Northern Hemisphere, the vaccines that the CDC approved include vaccines against the following three types of flu: 1. A/California/7/09 (H1N1)-like virus (Pandemic (H1N1) 2009 influenza virus) 2. A/Perth/16/2009/ (H3N2)-like virus 3. B/Brisbane/60/2008-like virus Influenza (flu) is caused by viruses and the vaccinations evoke an immune response to create antibodies that will rapidly inactivate the viruses so your body can eliminate them. The viruses contained in the flu vaccines are either inert ("dead"), or "live" which means they are active but weakened significantly, so they are unable to cause infections but are still strong enough to trigger your immune response and provide the resulting immunization.
If you mean drink alcohol, it would be best not to, especially not to excess. You can sometimes get a low grade fever after a vaccination for the flu and since alcohol and fev…ers can cause dehydration, and headaches are not uncommon, it is better to give your body plenty of fluids and rest and it can do the job of creating your immunity better.
I bet it is to prevent the Flu.
Yes, it will cause your body to create immunity to the specific kind of flu that the vaccine is made to prevent. It is possible for you to get a different type of flu, though,… if the shot did not include vaccine to prevent the one you caught. See related questions below for more details about vaccinations.
In Cold and Flu
Not directly. The flu shot only prevents the flu the vaccine in the shot is made to prevent. However, you could say it prevents you from having bronchitis in some ways of lo…oking at it. Sometimes, especially in people prone to upper respiratory infections (e.g., asthmatics and people with other forms of obstructive lung disease), there is often a secondary infection after the flu or along with the flu that causes bronchitis or pneumonia. If you consider that the flu shot prevented the flu, then you would also be preventing the secondary infections, too. However, if you are exposed to viruses or bacteria that cause the pneumonia or bronchitis, having taken a flu shot will not protect you from catching those infections.
No. The influenza vaccine is only for preventing respiratory influenza (flu). The norovirus ("Norwalk Flu") is one of the viruses that cause the "stomach flu", more correctl…y called viral gastroenteritis, since it is actually not the flu. There is no available vaccine yet, but one is in clinical trials, so it could be licensed for use in the US in a relatively short time.
In Cold and Flu
Yes, it is common practice to give immunization for flu and pneumonia at the same time.
Technically, you cannot prevent infection with seasonal influenza viruses even after the annual vaccination (flu shot). The virus could still be considered to have "infected" …you by entering one of your cells. What a vaccine does is allow your body to more quickly disable the virus before it can make you feel sick. What the annual vaccine does is prepare your immune system against the specific influenza viruses so your body knows what antibodies to make to deactivate the invading flu viruses. Actual prevention of infection would take complete viral isolation from the world, as the influenza virus is ubiquitous among humans. With the vaccines, it is the illness from the infection that is prevented. To prevent flu illness you can use strict precautions to avoid exposure, but these may not be totally effective. Most infectious disease experts suggest both using the annual seasonal flu vaccines as well as careful hand hygiene and other preventive measures to avoid flu illnesses. See the related questions below for more information on how flu shots and the immune system work together to prevent illness.
