Who Needs To Get The Flu Vaccine REASONS ALL AGES SHOULD GET IT
Why people get vaccinated against the flu?
Influenza is a serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently. Even healthy people will get very sick from the flu and spread it to others. Over period of 31 seasons between 1976 and 2007, estimates of flu-associated deaths in the United States range from a low of about 3,000 to a high of about 49,000 people. During a regular flu season, about 90 percent of deaths occur in people 65 years and older. The “seasonal flu season” in the United States can begin as early as October and last as late as May. During this time, flu viruses are circulating in the population. An annual seasonal flu vaccine (either the flu shot or the nasal-spray flu vaccine) is the way to reduce the chances that you will get seasonal flu and lessen the chance that you spread it to others. When more people get vaccinated against the flu, less flu can spread through that community.
How do the flu vaccines work?
Flu vaccines (the flu shot and the nasal-spray flu vaccine (LAIV)) cause antibodies to develop in the body about two weeks after vaccination. These antibodies provide protection against infection with the viruses that are in the vaccine.The seasonal flu vaccine protects against three influenza viruses that research indicates will be most common during the upcoming season. Three kinds of influenza viruses commonly circulate among people today: influenza B viruses, influenza A (H1N1) viruses, and influenza A (H3N2) viruses. Each year, one flu virus of each kind is used to produce seasonal influenza vaccine.Top
What kinds of flu vaccines available?
There are two types of vaccines:
The “flu shot” — an inactivated vaccine (containing killed virus) that is given with a needle, usually in the arm. The flu shot is approved for use in people older than 6 months, including healthy people and people with chronic medical conditions.
The nasal-spray flu vaccine — a vaccine made with live, weakened flu viruses that is given as a nasal spray (sometimes called LAIV for “Live Attenuated Influenza Vaccine”). The viruses in the nasal spray vaccine do not cause the flu. LAIV is approved for use in healthy* people 2 through 49 years of age who are not pregnant.
Seasonal flu vaccines protect against the three influenza viruses (trivalent) that research indicates will be most common during the upcoming season. The viruses in the vaccine can change each year based on international surveillance and scientists’ estimations about which types and strains of viruses will circulate in a given year. While some manufacturers are planning to produce a quadrivalent (four component) vaccine in the future, quadrivalent vaccines are not expected to be available for the 2012-2013 season.About 2 weeks after vaccination, antibodies that provide protection against the influenza viruses in the vaccine develop in the body. Information specific to the 2012-2013 season including the flu vaccine formulation, can be found at 2012-2013 Flu Season.
Who Should be Vaccinated This Season?
Everyone who is at least 6 months of age should get a flu vaccine this season. It’s especially important for some people to get vaccinated. Those people include the following:
People who are at high risk of developing serious complications like pneumonia if they get sick with the flu. This includes:
People who have certain medical conditions including asthma, diabetes, and chronic lung disease.
People 65 years and older
People who live with or care for others who are high risk of developing serious complications. This includes:
household contacts and caregivers of people with certain medical conditions including asthma, diabetes, and chronic lung disease.
There are some people who should not get a flu vaccine without first consulting a physician. These include:
People who have a severe allergy to eggs.
People who have had a severe reaction to an influenza vaccination.
Children younger than 6 months of age (influenza vaccine is not approved for this age group), and
People who have a moderate-to-severe illness with a fever (they should wait until they recover to get vaccinated.)
People with a history of Guillain–Barré Syndrome (a severe paralytic illness, also called GBS) that occurred after receiving influenza vaccine and who are not at risk for severe illness from influenza should generally not receive vaccine. Tell your doctor if you ever had Guillain-Barré Syndrome. Your doctor will help you decide whether the vaccine is recommended for you.
When Should I Get the Vaccinated?
CDC recommends that people get vaccinated against influenza as soon as flu season vaccine becomes available in their community. Influenza seasons are unpredictable, and can begin as early as October.It takes about two weeks after vaccination for antibodies to develop in the body and provide protection against the flu.Flu vaccine is produced by private manufacturers, so availability depends on when production is completed. If everything goes as indicated by manufacturers, shipments are likely to begin in August and continue throughout September and October until all vaccine is distributed.At this time, some vaccine providers may have exhausted their vaccine supplies, while others may have remaining supplies of vaccine. People seeking vaccination may need to call more than one provider to locate vaccine. The flu vaccine locator at http://vaccine.healthmap.org may be helpful.Top
Where can I get a flu vaccine?
Flu vaccines are offered in many locations, including doctor’s offices, clinics, health departments, pharmacies and college health centers, as well as by many employers, and even in some schools.Even if you don’t have a regular doctor or nurse, you can get a flu vaccine somewhere else, like a health department, pharmacy, urgent care clinic, and often your school, college health center, or work.The following Vaccine Locator is a useful tool for finding vaccine in your area.
Why Do I Need a Vaccine Every Year?
A flu vaccine is needed every year because flu viruses are constantly changing. It’s not unusual for new flu viruses to appear each year. The flu vaccine is formulated each year to keep up with the flu viruses as they change.Also, multiple studies conducted over different seasons and across vaccine types and influenza virus sub types have shown that the body’s immunity to influenza viruses (acquired either through natural infection or vaccination) declines over time. Getting vaccinated each year provides the best protection against influenza throughout flu season.
Does the vaccine work right away?
No. It takes about two weeks after vaccination for antibodies to develop in the body and provide protection against influenza virus infection. In the meantime, you are still at risk for getting the flu. That’s why it’s better to get vaccinated early in the fall, before the flu season really gets under way.
Can I get seasonal flu even though I got flu vaccine this year?
Yes. The ability of flu vaccine to protect a person depends on two things: 1) the age and health status of the person getting vaccinated, and 2) the similarity or “match” between the virus strains in the vaccine and those circulating in the community. If the viruses in the vaccine and the influenza viruses circulating in the community are closely matched, vaccine effectiveness is higher. If they are not closely matched, vaccine effectiveness can be reduced. However, it’s important to remember that even when the viruses are not closely matched, the vaccine can still protect many people and prevent flu-related complications. Such protection is possible because antibodies made in response to the vaccine can provide some protection (called cross-protection) against different, but related strains of influenza viruses.

"Carlie and Krystal are the two friendliest and knowledgeable agents I have ever met. Since I was relocating to Arizona from California, they showed me numerous homes in the limited time period that I was in town. They had everything printed out and organized into a binder for me to take notes and I got nothing short of the royal treatment. They were able to expertly answer all of my questions about areas, property values, financing and the entire process of buying a home whether it be a short sale or a foreclosure. It was a pleasure to meet and work with them. I will continue to refer my friends and family to Carlie and Krystal. Thanks ladies!!!"
