A recent report released by Trust for America’s Health called Fighting Flu Fatigue provided some startling statistics about H1N1 and the impact it had across the United States during the 2009-2010 flu season.
According to the report, H1N1 infected around 20 percent of Americans (approximately 60 million individuals) and resulted in approximately 274,000 hospitalizations and 12,000 deaths. Read the entire report here.
Despite the alarming number of people affected by H1N1 last flu season, there is a real likelihood that the United States will return to complacency in its attitude toward the flu. This could be because there was a perception that H1N1 was not as serious as it was made out to be, or because the H1N1 vaccine is now part of the regular seasonal flu vaccine. Nevertheless, H1N1 and the flu as a whole are not something to be complacent about and each year the country continues to face serious health threats.
The flu is often seen as a nuisance, but it is actually very serious. According to the Centers for Disease Control and Prevention (CDC), between 1976 and 2007, flu-related deaths in the United States have ranged from a low of around 3,000 to a high of 49,000 Americans each year.
The flu is also costly to companies and businesses across the country as people who get the flu do not come to work, thus possibly costing employers productivity. In fact, the flu contributes to more than $10 million in lost productivity and direct medical expenses in the United States each year and another $16 billion in lost potential earnings.
Remember, getting your flu vaccine is the single best way to prevent getting the flu this season.

Schools, hospitals, corporations… it seems that everyone is jumping on the flu vaccine bandwagon… and for good reason! The flu is a serious illness that can lead to even more serious complications, including death. Organizations around the nation are recognizing the benefits to keeping their people healthy by making flu shots readily available.
Take a look at how the flu is gripping headlines across the nation…
1) “NH starts flu clinics in schools” Boston Globe (MA) (November 9, 2010) – “New Hampshire public health officials are starting flu clinics at selected schools and hope to vaccinate half of the state’s school age children. About 100 schools will hold clinics in the coming months in Belknap, Coos and Grafton counties as well as in the greater Manchester area. The government recommends that everyone over 6 months old get vaccinated. This year’s vaccine protects against three strains of the flu including last year’s H1N1 virus. The state is providing the vaccine through its immunization program. The cost of administering the shot will be paid by the child’s insurance or the state immunization program. The pilot project covers registered students in participating districts and not younger siblings, parents or staff.” Continue reading…
2) “Hospitals Statewide Adopt Flu Vaccine” KPLU (NPR) (WA) (November 9, 2010) – “Nearly every hospital in Washington has now adopted a mandatory flu-shot policy for hospital workers. That makes Washington the first state in the nation where nearly every hospital employee will be immunized… Then, a bill to make this policy a state law failed in the legislature. So, the hospital association decided this summer to make it a campaign. Now, 94 out of 98 hospitals in the state have signed on, with four tiny rural hospitals still waiting to make the transition. Sauer says it represents a better understanding of what’s at stake.” Continue reading…
3) “Flu shots can pay off big for employers” Los Angeles Times (CA) (November 10, 2010) – “Flu vaccinations for employees can help an employer’s bottom line, according to a new study. Research presented Tuesday at the annual meeting of the American Public Health Assn., found that for each employee vaccinated an employer can save $63 to $95 per person. Vaccinating an entire 150-person company, for example, could yield savings of between $9,450 and $14,250. The study analyzes the cost of providing flu vaccine to employees and the costs in terms of absenteeism and lost productivity from having some workers out with the flu. The key to big savings, however, is to immunize workers early in the flu season. If an employer holds a flu clinic after December, the savings won’t add up. The savings to an employer are especially significant if a flu clinic is held early in a year when a pandemic flu is circulating. In that case, vaccination can save an employer $33.94 to $700.69 per vaccinated employee.” Continue reading…
4) “Flu shot safe for pregnant women, study finds” Reuters Health (November 11, 2010) – “The safety of the flu shot, which is made using killed influenza virus, has been studied in about 10,000 pregnant women, with no evidence that it presents a particular risk in this group… These latest findings ‘add to the existing evidence that the (flu shot) is safe for pregnant women,’ lead researcher Dr. Pedro L. Moro, of the U.S. Centers for Disease Control and Prevention in Atlanta, told Reuters Health. Public health officials, as well as medical groups like the American College of Obstetricians and Gynecologists, recommend that all pregnant women receive the flu shot — though not the nasal-spray flu vaccine, which is made from a live, weakened virus.” Continue reading…
5) “Infection control” Boston Globe (MA) (November 8, 2010) – “Q. What did H1N1 teach us last year? A. I think the important lesson of the influenza pandemic is pandemics do occur. Q. Will people become complacent about pandemic flu, too? A. You need to get as many people vaccinated as you possibly can every year for the seasonal influenza and when you get the unpredictable emergence of a pandemic influenza, you will already have the infrastructure in place to make and distribute vaccine to as many people as you possibly can. In fact, that is what we are doing. Each year we vaccinate more and more people. We used to vaccinate 20, 30, 40, 50 million people a year each season. This year 160 million people will get vaccinated for the seasonal flu.” Continue reading…

As flu activity picks up, the theme this week seemed to focus on the extensive reasons to get a flu shot, with headlines ranging from the abundance of flu vaccine this year to why expectant mothers need to get their flu shots to staying healthy for the holidays. One thing is for sure, this is a great time to pay a visit to your local flu shot clinic before the season fully gets underway.
Below are just a few examples of how the flu is making headlines across the nation…
1) “Flu vaccine widely available” Democrat and Chronicle (NY) (October 28, 2010) – “Flu vaccine is widely available at public clinics, doctor’s offices and pharmacies, but the cost may vary depending on where you go. Insurance plans may only cover vaccinations from certain places, so check with your insurer or check the website of the clinic provider… Monroe County: More than 150 walk-in flu clinics have already been held and about three dozen flu clinics remain from today through Nov. 20, offered by Flu Prevention Partners, Independent Nursing Care, Maxim Health Systems and University of Rochester Medical Center. For a recorded list, call (585) 753-5600, or go to www.monroecounty.gov/health-flu.” Continue reading…
2) “Exercise helps fend off colds and flu” KJRH (OK) (November 1, 2010) – “Remember the old saying, ‘An apple a day keeps the doctor away?” Here’s a modern twist: “A bit of exercise every day may keep the doctor away.’ Researchers from Appalachian State found the more physically active people were — the fewer colds they got during the fall and winter months. And when they did get colds — their symptoms were less severe than more sedentary people. Doctors say bouts of exercise can temporarily increase the immune system’s response to potential viral invaders in the body. The findings were published in the British Journal of Sports Medicine.” Continue reading…
3) “Expectant moms’ flu shots protect newborns” KING5 (WA) (October 30, 2010) – “After her newborn’s pediatric visit, new mom Jennifer made one more stop, to Seattle Children’s flu vaccine clinic. ‘I came to get my flu vaccine so that hopefully I don’t get the flu and don’t share it with her,’ she said. At just 11 weeks old, baby Minnie can’t get a flu shot. Research shows the vaccine isn’t effective for babies under six months of age. It can be a risky interval explains Seattle Children’s pediatrician Dr. Danielle Zerr. ‘When babies get the flu they can develop high fever. They can develop a respiratory infection or an infection in their lungs that makes it difficult for them to breathe,’ she said. Dr. Zerr is an associate professor of pediatrics at Seattle Children’s. She said a new study suggests there’s a way moms can lower influenza’s toll on babies – by getting the shots before they’re even born.” Continue reading…
4) “Your head says cold, but your body screams influenza” Columbus Dispatch (OH) (October 31, 2010) – “It’s that time of year, and you’re sick. So, is it a cold or flu? Sure, they have some things in common. Both are caused by viruses, circulate mostly in the winter months and shouldn’t be treated with antibiotics. But there are also some pretty big differences. If you’re tempted to compare your suffering to that of a person run over by a large vehicle, it’s probably the flu. Either that, or you’re a bit of a drama queen. Flu knocks out the most stalwart, sending them to bed wishing their mommy would press a cool washcloth to their forehead.” Continue reading…
5) “Jon Law: Get flu vaccine now and enjoy holidays” El Paso Times (TX) (November 1, 2010) – “Autumn, my favorite season, is now in full swing. Cooler weather and UTEP football games are welcome reminders that the holiday season is coming soon. While we’re a long distance from New England’s illustrious fall foliage, a few of our local tree leaves are even turning yellow, orange and brown. And, it’s also the time for an important, but less glorious, ritual — the annual flu vaccine.” Continue reading…

Many associate the flu with winter, and while it’s true, according to the Centers for Disease Control and Prevention (CDC),that flu activity most commonly peaks in the United States in January or February[i], the country is already starting to see confirmed flu outbreaks, and in certain cases, death.
Last week we posted about the lack of motivation some have to get vaccinated this flu season now that the attention to H1N1 that gripped last year’s flu season has waned. Many people are simply unmotivated to get the vaccine this year because the perception is that this season will be much milder. However, that perception does not lessen the risks of not getting vaccinated. Last week alone there were at least two confirmed cases of people being hospitalized because of the flu, and in one case a flu-related death. Below are a couple examples of recent flu activity across the country:
- In Oklahoma, a resident died of influenza between October 3 and October 10 according to the state Health Department’s Web site. Also, since September 1, nine residents have been hospitalized with the flu.[ii]
- In Michigan, the first two flu cases were confirmed in Oakland County, this according to the Michigan Department of Community Health.[iii]
In addition to these confirmed cases, the CDC came out with their first weekly flu activity report of the year. According to FluView, a weekly influenza surveillance report from the CDC, during the week of October 17-23 influenza activity remained low in the United States, making it a great time to get a flu shot.
Last week’s confirmed cases are a testament to the fact that the height of flu season is approaching and that the best defense against the flu is to get a flu shot.
Hundreds of flu shot clinics are conveniently located throughout the country. Use our clinic search to find a flu shot clinic near you and get your flu shot to protect yourself and your family this flu season.

As parents, teachers, and most adults know, children have a way of picking up colds and other illnesses at school. As flu season approaches, it becomes even more important to teach kids how to stay healthy. While the number one way to prevent the flu is to make sure your child gets his or her flu shot, proper and consistent hand washing is one of the easiest ways to also help prevent the spread of influenza. Kids don’t always listen when you tell them to wash their hands, but it’s a message worth repeating. When your children come into contact with germs or viruses such as the flu, they can unknowingly become infected simply by touching their eyes, nose, or mouth. Once infected, it is usually only a matter of time before the whole family gets sick as well.
Germs can be spread or transmitted in many ways, including:
- touching dirty hands or contaminated surfaces, such as doorknobs, desks, or books
- sharing objects such as utensils, cups, or bottles
- through droplets released during a cough or a sneeze
- through contact with a sick person’s body fluids
Teach Good Health Habits
To minimize the germs passed around your family, and to protect yourself from the flu this season, make frequent hand washing a rule for everyone, especially:
- before eating
- after using the bathroom
- after cleaning the house
- after touching animals, including family pets
- before and after visiting any sick friends or relatives
- after blowing your nose, coughing, or sneezing
- after being outside (playing, walking the dog, etc.)
You can even show your children how to get rid of germs by taking these steps when washing your hands together so they learn how important this good habit is:
- Wet hands with warm water and apply soap, making sure the water isn’t too hot for little hands.
- Rub hands together vigorously for at least 20 seconds, covering all surfaces of the hands and giving extra attention to under the fingernails and between the fingers where uninvited germs like to hang out. (For younger children who may rush hand washing, have them sing a short song such as “Row, Row, Row, Your Boat,” or “Happy Birthday”, which will ensure they wash for at least 20 seconds.)
- Rinse hands with water.
- Dry thoroughly with a clean, disposable towel.
- Use towel to turn off faucet.
Educational Tools
Parents can reinforce their children’s hand-washing habits by using tools such as The Scrub Club®. The Scrub Club® is a collaborative effort between the American Red Cross and NSF International (NSF) to help protect public health by teaching children the importance of proper and consistent hand washing to help fight germs and prevent illnesses like the flu. The interactive Web site offers free educational materials, music, games, and cartoon “Webisodes” to help raise awareness about the benefits of hand washing.
While the Centers for Disease Control and Prevention (CDC) is recommending that everyone receive their flu shot this year as the best way to prevent the flu, it is important not to underestimate the power of hand washing in helping to stop the spread of influenza. Make it a fun experience for your kids. The few seconds you spend at the kitchen or bathroom sink could save you trips to the doctor’s office this flu season.

Bloomberg Businessweek reported recently on a survey released by the National Foundation for Infectious Diseases (NFID) that found 43 percent of Americans do NOT plan to get vaccinated against flu this year, a startling number considering the focus H1N1 put on the flu virus last season.
The NFID also asked those surveyed why they planned to skip vaccination. Many of the reasons given included common myths about the flu and the flu vaccine. While reasons for skipping vaccinations range from misconceptions about transmission to taking flu lightly, one thing remains true: influenza is more than an inconvenience. It is a serious illness that can cause weeks of sickness or even death. According to the Centers for Disease Control and Prevention (CDC), more than 200,000 people are hospitalized for flu-related complications each year. That’s an average of one person almost every 2 ½ minutes!
We took a look at some of the reasons people gave for skipping flu shots this season and sorted through some of the fact and fiction of flu. Below are some of the most common myths that people use as reasons for not getting a flu shot.
Myth: The flu shot can give you the flu
Of the people in the NFID survey who said they did not plan to get a flu shot this year, 62 percent said that a reason for not getting the shot was because the vaccine could give you the flu or because of a concern about side effects. The fact is the flu vaccine can’t give you flu. The injectable flu vaccine contains killed influenza viruses and side effects typically include soreness where the flu shot was given and sometimes aches or a low-grade fever.1 The CDC has a great informational page with key facts about the flu shot that gives details about vaccination and dispels some of the myths.
Myth: There are other ways to protect yourself
Many people in the NFID survey said that they don’t plan to get the flu shot because there are other ways they can protect themselves. But unless you plan to live in isolation for the duration of flu season, nothing will be more effective in influenza prevention than a flu vaccine. Thirty-four percent in the survey thought that hand-washing was as effective as the vaccine in preventing influenza. While hand washing is an important part of protection, it is only a part of the bigger picture. The CDC says that vaccination is the single best way to protect you and your family against flu. Keep in mind, just because you washed your hands doesn’t mean that a person with flu didn’t just touch that door knob you were using. And teaching your children to wash their hands doesn’t mean that they won’t be exposed to germs while at school or on the playground.
Myth: I’m healthy
The survey from NFID found that 69 percent of people who were not planning to get a flu shot held the belief that they are healthy and the flu doesn’t worry them. While it is true that there are groups of people at higher risks for complications from flu, the flu doesn’t discriminate and can impact both the frail and healthy in severe ways. For example, last year the H1N1 virus disproportionately impacted otherwise healthy children and almost 90 percent of deaths occurred in people under the age of 65. 2 Also, keep in mind that the flu shot doesn’t just protect you, but your loved ones, too. If you are around children, the elderly, or people who are in a high-risk group you getting vaccinated means that you are at a lower risk of passing on the flu virus to them.
Myth: The vaccine protects against just one strain of flu so it won’t be effective
Some people think that the flu vaccine protects against just one strain of the flu virus. The fact is, the flu vaccine contains protection against three different strains of influenza. This year, one of the strains the vaccine protects you against is H1N1. The process for deciding what strains go into the flu vaccine involves year-round surveillance and reporting from 101 countries to determine what strains are most likely to take hold each flu season. Based on that research, researchers in the United States determine which strains should be included in the vaccine distributed to the United States population.3 The CDC has already reported lab confirmed influenza cases in the United States for each of the three strains included in this years seasonal influenza vaccine.
Myth: Getting the flu shot takes too much time
Another excuse a lot of people give for not getting vaccinated is time. But time is no longer an excuse with thousands of flu clinics all over the country in convenient locations. People can now get their flu shots while grocery shopping, while at the mall, or in a variety of other convenient locations. Use our flu locator tool to find a clinic near you. When you find a clinic you can even sign up for a text message or e-mail reminder so you are reminded as your local flu clinic approaches.
By the way, one person that is probably getting vaccinated this year? Your doctor. A NFID survey of 400 physicians from September found that more than 90 percent are getting vaccinated this year and most recommend their families get vaccinated, too. As always, any health decisions should be discussed with a trusted physician, so if you still have questions about flu and how it applies to you, be sure to talk to your doctor about the best ways to protect yourself this flu season.

After a long hot summer, fall is here. And the fall/winter season also means cold and flu season
In 2009, with the emergence of the first global influenza pandemic in more than 40 years, organizations and businesses were preparing for the worst, fearing the possibility of widespread illness, substantial absenteeism, and other business disruptions. Compared to last year, the current media hype surrounding the flu seems relatively non-existent. But don’t let that deceive you as we head into this flu season. Now is not the time to let down your guard, either personally or professionally.
Despite the fact that the peak of flu season does not typically occur until January or February, and the uncertainties around how bad this flu season will be, we do know one thing for sure- that the flu shot is the best way to protect yourself and those around you. According to a recent post by Dr. Paul Biddinger* on the Harvard Business Review’s “Your Health at Work” blog, getting your shot is the most important thing you can do for yourself, your co-workers, family, and friends. This is because it is possible to transmit the flu for one or two days before you actually start feeling sick, and therefore the time you could unknowingly spread the virus to those around you. It is best to get your flu shot earlier rather than later because your body needs time to develop antibodies in preparation for the peak season, as well as your best protection against an early arrival of flu season. As of October 7th, 2010 the CDC has lab confirmed cases of influenza from each of the three strains included in the seasonal flu vaccine.
The more people who get vaccinated the better it is for your family, workplace, and community. Many companies offer employee vaccination programs, making it easy for you to conveniently receive your flu shot right at work. If your company doesn’t have an employee vaccination program, urge your employer to get one to make it easier for you and your coworkers to get the flu shot. (This video and this article could help you in giving them the 411 on Flu in the Workplace.) Remember, it isn’t good for you, your co-workers, or your employer if you are going to work sick.
So as you get ready for the fall season, remember —one simple flu shot will give you the best possible protection against the flu. Get yours today-find a convenient location now at www.findaflushot.com.

October is recognized annually as National Breast Cancer Awareness Month. Throughout the month, national public service organizations such as The American Cancer Society and Susan G. Komen for the Cure® work tirelessly to promote information on breast cancer awareness and prevention.
October also marks the time of year when influenza starts to become active and is the best time for people to receive their influenza vaccine. The Centers for Disease Control and Prevention (CDC) recommends that everyone age six months and older receives a flu shot, especially people that are at high risk of developing flu-related complications. This includes people who have immune system problems caused either by disease (e.g. breast cancer or lymphoma) or by medication (e.g., chemotherapy or radiation therapy)[1]
What else is important for cancer patients and survivors to know about the flu this season? Below is valuable information from The American Cancer Society specific to cancer patients and the flu.
- First, and perhaps the most sobering, is that both cancer patients and survivors are more likely to have serious problems from the flu, resulting in hospitalization or even death. While no one knows for sure if cancer patients and survivors are at greater risk for being infected with either H1N1 or seasonal flu, they are at higher risk for having serious problems from the flu. Therefore, even if cancer patients are at the same risk of getting the flu, once they contract either type of flu, they are at higher risk of complications.
- Second, if you or a loved one has had cancer in the past, there is a greater risk for having serious complications from the flu, even if you are now cancer-free.
- Third, the flu shot is recommended for most people with cancer. However, many people with cancer worry that the vaccine will make them sick or cause a reaction with other medicines they are taking. Talk to your doctor about this — he or she knows your situation best and can tell you if you should get the shot and when is the best time to get it.
- Finally, people with cancer should get the injectable flu shot and not the nasal spray vaccine. The flu shot is made from dead or inactive viruses, so it cannot make you sick. [2] The nasal spray vaccine is made from a live attenuated virus, and is currently not advised for high risk individuals.

The outbreak of whooping cough, also known as pertussis, in Texas, California, and other states this year highlights the significant importance of widespread vaccination coverage. Vaccination of children and adults can prevent pertussis, and experts say that the lack of vaccine coverage among adults in the US is one of the main reasons for the upsurge of this disease over the last two years[i].
This brings up the concept of ‘herd immunity’. Herd immunity is an important part of protecting the community against illnesses such as pertussis or influenza. Infants, who are too young to be immunized against the flu or whooping cough, are at particular risk. Because vaccinated people have antibodies that neutralize a virus, they are much less likely to transmit that virus to other people. Therefore, even people who have not been vaccinated, as well as those whose vaccinations may have become weakened over time, can often be shielded from the virus by ‘herd immunity’ because vaccinated people around them are not getting sick.
Health officials recommend that parents and caretakers receive their flu vaccines and pertussis booster shots to extend their immunity to these diseases and lower the risk to infants[ii]. Herd immunity is more effective as the percentage of people vaccinated increases. It is thought that on average approximately 90 percent of the people in the community must be protected by a vaccine to achieve herd immunity[iii]. People who are not immunized increase the chance that they and others will get sick.
This flu season, The Centers for Disease Control and Prevention (CDC) has made a universal recommendation that everyone over the age of 6 months receive the seasonal flu shot. The flu vaccine is the best way to protect your family against the disease. Children less than 6 months of age are too young to be vaccinated against influenza, but they are at the greatest risk of hospitalization for it[iv]. Therefore, this year, and every year, in order to best protect yourself and those around you who are under the age of 6 months, at high risk for contracting influenza, or unable to get the vaccine, it is critical for you and any other household contacts or caregivers to get vaccinated.
Have you gotten your flu shot yet? Protect your family and everyone in your household from the flu, get your flu shot today and remind your friends to do the same!

Posted October 1, 2010 | Filed in CDC Alerts, Flu Shots, H1N1 (Swine Flu)
Given the prevalence of H1N1 last season, there have been a lot of mixed messages floating around regarding the composition of this season’s flu vaccine. Here is the story: The 2010-2011 seasonal influenza vaccine consists of protection against the H1N1 strain, plus two additional influenza strains that have been identified as the primary circulating influenza strains for this year. You can visit the Centers for Disease Control and Protection (CDC) Web site for more detailed information on the specific strains it includes.
It’s important to know that this is not a change from previous seasons. Every year, the influenza vaccine is compromised of three strains. According to the CDC, “the viruses used in making seasonal flu vaccines are chosen each year based on information collected over the previous year about which influenza viruses are spreading and what vaccine viruses would offer the best protection against circulating viruses.”
Last year’s flu season (2009-2010) was not the norm. Because of the emergence of the new H1N1 virus, two vaccines were needed: one to prevent seasonal influenza viruses that were anticipated to spread and another to prevent influenza caused by the newly emerged 2009 H1N1 virus[i]. If the 2009 H1N1 virus had emerged sooner, it would have been included in the seasonal vaccine. That is why we saw a second flu vaccine created last year to protect against the new flu virus[ii].
The ability of the influenza virus to shift to different strains from one season to the next, or even within the course of one flu season, explains why you can potentially get the flu year after year[iii]. This is also why you hear the recommendations to get a new flu shot each year- because you could potentially be infected by a different flu strain that is unfamiliar to your immune system. This is also precisely why it is so important to get a flu shot. It gives your immune system a leg up in protecting you against these new or unfamiliar strains.
Everyone ages 6 months and older is now recommended to receive seasonal influenza vaccine, regardless of past immunization history. Even those individuals who received monovalent H1N1 in 2009 require a new 2010 seasonal influenza shot for maximum protection.
This flu season, don’t take any risks, protect yourself by getting a flu shot today!
