New reports from the U.S. Centers for Disease Control and Prevention (CDC) show that 39 percent of adults and 41 percent of children six months and older got their flu shots for the 2013-2014 season by early November—a rate similar to flu vaccination coverage last season at the same time.
Other flu shot statistics of note this year include:
- Vaccination among pregnant women (41 percent) and health care providers (63 percent) is about the same as it was this time last year
- High rates were seen again this year among health care providers including pharmacists (90 percent), physicians (84 percent) and nurses (79 percent), but the CDC reported much lower vaccination rates among assistants or aides (49 percent) and health care providers working in long-term care facilities (53 percent)
“We are happy that annual flu vaccination is becoming a habit for many people, but there is still much room for improvement,” says Anne Schuchat, MD, director of the National Center for Immunization and Respiratory Diseases at CDC. “The bottom line is that influenza can cause a tremendous amount of illness and can be severe. Even when our flu vaccines are not as effective as we want them to be, they can reduce flu illnesses, doctors' visits, and flu-related hospitalizations and deaths.”
Seasonal influenza activity is increasing in parts of the United States. Further increases in influenza activity across the country are expected in the coming weeks. “If you have not gotten your flu vaccine yet this season, you should get one now,” said Schuchat.
The CDC’s report comes just ahead of the observance next week of National Influenza Vaccination Week (NIVW), which is scheduled each year for the second week in December because vaccination rates tend to fall off toward the end of November. It’s hardly too late to get the flu vaccine: flu season usually peaks January through March, and the virus—and the potential to catch it—often lasts as late as May.
People who haven’t had the flu shot should make it a priority to do so as soon as possible for at least two reasons. One, providers tend to return their unused vaccines toward the end of the year, which can make it hard to find a vaccine if you still need the shot (check this flu vaccine finder for providers in your area, and call ahead to be sure they have supplies on hand). Two, it takes two weeks for the flu vaccine to take full effect, so the sooner you get it the more protected you are against people harboring the flu during the upcoming holiday party season.
Still on the sidelines about getting the shot? The CDC has some impressive numbers from last year’s flu season: flu vaccination prevented an estimated 6.6 million influenza-associated illnesses and 79,000 hospitalizations during the 2012-2013 flu season.

The flu season is pretty mild so far. The latest FluView report from the U.S. Centers for Disease Control and Prevention (CDC) shows that the current rate of flu cases across the country is below other years, and some states have yet to see any flu cases at all. But health experts worry those reports will make people who still haven’t gotten the vaccine complacent about getting their shot. And going without poses the risk of a multi-day illness; transmitting the flu to other people who may be more vulnerable to the virus than you; and the potential for serious side effects such as pneumonia and—in rare cases—death.
If you’re still shotless, health experts advise you to roll up your sleeves by Wednesday if at all possible. Here’s why: Immunity to the flu can take up to two weeks after you’ve received the injection. Get the shot by this Wednesday, November 13, and you’ll be protected by the day before Thanksgiving.
That’s the heaviest U.S. travel day of the year, when the possibility of encountering people with the flu at airports, train stations, or even at Thanksgiving dinner greatly increases.
“Visiting mom, grandma and that new baby can make for memorable holiday moments, as long as you don't bring the flu virus along to spoil the party,” says Jeff Golden, spokesman for the Madison, Wisc., health department which, like many other health departments, has sent out recent flu advisories.
CDC research adds another reason to get the shot this week. The agency has found that the momentum to get the flu vaccine wanes after Thanksgiving, perhaps because people assume that as the weather gets colder, if they haven't gotten influenza yet, they won’t. But that’s foolhardy thinking. The U.S. flu season runs from September through April, and the worst of it often hits in January and February. If you wait until cases increase, you may find that you don’t have enough time for the shot to protect you. And you may also find it hard to locate supplies of the vaccine. Knowing that interest in the shot drops after Thanksgiving, private and public clinics, as well as doctors’ offices, often return unused supplies toward the end of the year to free up storage space and in some cases get a refund on the unused doses. Health departments may then keep supplies centrally, but that location may not be convenient.
Wonder where to get the flu shot? Here are good ideas:
- Key in your zip code at flu.gov
- Dial 211, a resource for local services in many communities
- Check pharmacies to see if they have supplies on hand and what hours they give the shots
- Call your local health department to ask if they have clinic hours for the flu vaccination
- Key in “travel clinic” on a search engine to find private clinics in business districts, but call ahead to check on supplies and hours
Health departments may give the shot for free, or ask for payment on a sliding scale based on income. Pharmacies charge about $25, and private doctors’ offices may add a $10 or $20 administrative fee on top of that. The cost is typically covered by insurance, though you may have to file the paperwork yourself.
Medical Groups Issue New Definitions for Stages of Pregnancy
With a goal toward improving newborn outcomes and reducing non-medically related deliveries, the American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine (SMFM) are recommending four new definitions of ‘term’ deliveries:
- Early Term: Between 37 weeks 0 days and 38 weeks 6 days
- Full Term: Between 39 weeks 0 days and 40 weeks 6 days
- Late Term: Between 41 weeks 0 days and 41 weeks 6 days
- Post term: Between 42 weeks 0 days and beyond
Research over the past several years finds that every week of gestation matters for the health of newborns, and that babies born between 39 weeks 0 days and 40 weeks 6 days gestation have the best health outcomes, compared with babies born before or after this period. ACOG and SMFM encourage physicians, researchers, and public health officials to adopt these new precisely-defined terms in order to improve data collection and reporting, clinical research, and provide the highest quality pregnancy care. ACOG is a partner with the U.S. Department of Health and Human Services on “Strong Start,” a public awareness campaign to reduce unnecessary elective deliveries before 39 weeks’ gestation.

Poll Shows Americans Strongly Supporting Steps to Reduce Racial and Ethnic Inequality
A new poll conducted by the Center for American Progress and PolicyLink, and funded by The Rockefeller Foundation, finds that Americans are much more open to diversity and supportive of steps to reduce inequalities between racial and ethnic groups than has been previously thought. The poll was conducted by landline and cellphone in June and July among close to 3,000 U.S. citizens across the country. Some key findings of the poll include:
- Positive sentiments about opportunities from rising diversity tend to outweigh negative concerns.
- Sixty-nine percent of responders said that a bigger, more diverse workforce will lead to more economic growth and that diverse workplaces and schools will help make American businesses more innovative and competitive.
- More than 7 in 10 Americans support new steps to reduce racial and ethnic inequality in America through investments in areas such as education, job training and infrastructure improvement. Among Whites, the level of support was 63 percent.

CDC: Flu Season Slow So Far…But Should Pick Up Soon
While the flu season has seen relatively few cases so far, public health officials expect that to change soon and are heavily recommending that anyone who has yet to be vaccinated go ahead and do so. Joe Bresee, MD, chief of the epidemiology and prevention branch in the U.S. Centers for Disease Control (CDC) and Prevention's Influenza Division, said 135 to 139 million doses of vaccine should be available; the number of people who receive the vaccine annually has risen since 2009. "It's edging up in most groups, which is really gratifying, especially in some of the high-risk groups like pregnant women and kids. We are seeing good gains over the last four or five years," he said. "But we have a long way to go. Still only half of Americans get vaccinated. Vaccine is still the single best thing folks can do to prevent flu." Read more on the flu.
CDC Flu Reports to Resume Later Today
The U.S. Centers for Disease Control and Prevention (CDC) reported late yesterday that it has resumed analysis of influenza surveillance data and testing of influenza laboratory specimens collected during the 16-day government shut-down. An abbreviated FluView report summarizing the data for the most recent week (October 6-12) will be posted on Friday, October 18. At a later date, reports summarizing influenza surveillance data for September 22-October 5 will also be posted. Weekly Friday posting of the full FluView report for the 2013-2014 season will begin again on October 25. In the United States, flu season typically runs September through April and both private doctors and public health clinics currently have large supplies of this year’s flu vaccine on hand.

Brain May Flush Out Toxins During Sleep
A new study funded by the U.S. National Institutes of Health finds that a good night’s rest may literally clear the mind. The study, conducted in mice, showed—for the first time, according to the researchers—that the space between brain cells may increase during sleep, allowing the brain to flush out toxins that build up during waking hours. The researchers say that suggests a new role for sleep in health and disease. The study, published in Science, shows that during sleep a plumbing system called the glymphatic system may open, letting fluid flow rapidly through the brain. The researchers studied the system by injecting dye into the cerebrospinal fluid of mice and watching it flow through their brains while simultaneously monitoring electrical brain activity. The dye flowed rapidly when the mice were either asleep or anesthetized, but barely flowed when the same mice were awake. The researchers also inserted electrodes into the brains of the mice to directly measure the space between brain cells and found it increased by 60 percent when the mice were asleep or anesthetized. Researchers say the applications may apply to general health as well as have implications for neurological disorders. Read more on research.
New Report Offers Suggestions for Creating Healthier Neighborhoods
Again and again, research shows that our environment—where we live and what behaviors it fosters—has a profound impact on our health. Realizing this, a new report from the Prevention Institute offers interviews with fifty leaders in multiple sectors, including transportation, housing and public health on how to create healthy, safe and equitable neighborhoods. The goal of the report, Towards a 21st Century Approach: Advancing a Vision of Prevention and Public Health, is to spark an active and ongoing national dialogue about the subject. It was made possible through funding from the Robert Wood Johnson Foundation. Read more on smart growth.
Add flu surveillance to the list of casualties of the current government shutdown.
Every flu season, states collect data on flu cases — including case reports and viral specimens — and send those to the Centers for Disease Control and Prevention (CDC) in Atlanta for recording and tracking. That tracking is critical in order to:
- provide information on how well-matched the seasonal flu vaccine is to the flu viruses found in the community;
- identify severe outbreaks that require increased supplies of antiviral medicines for people who contract the flu; and
- identify emerging strains that might require a new vaccine to be developed this season, which is what happened several years ago when CDC identified the H1N1 influenza virus toward the end of the flu season, and quickly ramped up for a new vaccine.
Flu season generally runs October through April, with the peak from about January to March. If the shutdown continues then, “as the flu season goes on, our knowledge of what’s happening will be impaired,” says William Schaffner, MD, Professor of Preventive Medicine and Infectious Diseases, Vanderbilt University School of Medicine, and the immediate past president of the National Foundation for Infectious Diseases.
CDC director Thomas Frieden, MD, MPH, underscored his concern in a tweet on the first day of the government shutdown: “CDC had to furlough 8,754 people. They protected you yesterday, can't tomorrow. Microbes/other threats didn't shut down. We are less safe.”
State AGs Urge FDA to Adopt New Regulations Covering E-cigarettes
The Attorneys General of 41 states are urging the U.S. Food and Drug Administration (FDA) to follow through on a pledge to issue regulations that would expand its oversight to include e-cigarettes. In a letter to FDA Commissioner Margaret Hamburg, they asked “the FDA to move quickly to ensure that all tobacco products are tested and regulated to ensure that companies do not continue to sell or advertise to our nation's youth.” The FDA was given authority to regulate cigarettes, cigarette tobacco and roll-your-own tobacco in 2009, as well as the authority to expand its authority after it issued new regulations. Last week a similar plea related to FDA authority was made to President Obama by the American Academy of Pediatrics and 14 other public health organizations, including the American Lung Association and American Heart Association. E-cigarettes continue to increase in sales (a projected $1.7 million in 2013) even while dropping in price. At the same time, there are no advertising restrictions for e-cigarettes. "Consumers are led to believe that e-cigarettes are a safe alternative to cigarettes, despite the fact that they are addictive, and there is no regulatory oversight ensuring the safety of the ingredients in e-cigarettes,” according to the Attorneys General’s letter.

Expert: People Should Get Now-available Flu Vaccine As Soon As Possible
This season’s influenza vaccine is now available and people shouldn’t hesitate to go ahead and get it, according to Stephen Russell, MD, associated professor in the general internal medicine division at the University of Alabama at Birmingham and a lead physician at the university’s Medicine Moody Clinic. This year’s vaccine protects against four types of flu viruses (as opposed to the three of previous vaccines) and comes as either a traditional shot or a nasal spray. "Contrary to some beliefs, getting the flu shot in September is a good thing and will offer protection for the entirety of the flu season," he said. The U.S. Centers for Disease Control and Prevention recommends the vaccine for people ages 6 months and older, particularly for seniors, pregnant women, caregivers and people with chronic medical conditions. "Many people will say they do not need the vaccine, as they have never had the flu before, but that is like saying you don't need to wear your seatbelt because you have never had a wreck," Russell said. "You may have been fine in the past, but that should not offer security or protection for future exposures to the flu." Read more on influenza.
Study: Losing 10 Percent of Weight Can Greatly Reduce Arthritic Knee Pain, Put Off Knee Replacement
Losing just 10 percent of their weight could go a long way toward easing the knee pain from osteoarthritis in overweight and obese people ages 55 and older, according to a new study in the Journal of the American Medical Association. That would mean better knee function, improved mobility, enhanced quality of life…and reducing the odds of needed a knee replacement. "We've had a 162 percent increase in knee replacements over the last 20 years in people 65 and over, at a cost of $5 billion a year," said lead author Stephen Messier. "From our standpoint, we think this would be at least a good way to delay knee replacements and possibly prevent some knee replacements." The study tracked 454 overweight and obese people in three groups—diet-only, exercise-only and a combination—finding that people who did the combination were the most successful at losing weight and thus reducing knee pain. "We're not talking about people getting down to ideal body weight," said Patience White, MD, the Arthritis Foundation’s vice president of public policy and advocacy. "They just have to lose 10 percent of their total weight. Someone who is 300 pounds only needs to lose 30 pounds. I think that's within reach for people." Read more on obesity.
AAP: Children Should Be Immunized Against Influenza As Soon As Possible this Season
Parents and caregivers should have all children ages 6 months or older immunized against influenza as soon as possible, according to new updated recommendations from the American Academy of Pediatrics (AAP). Immunization options include the trivalent vaccine that protects against three influenza strains and the new quadrivalent vaccine that protects against four strains. “Parents should not delay vaccinating their children to obtain a specific vaccine,” said pediatrician Henry Bernstein, DO, FAAP, the lead author of the flu recommendations. “Influenza virus is unpredictable, and what’s most important is that people receive the vaccine soon, so that they will be protected when the virus begins circulating.” Other vulnerable groups that should definitely be vaccinated include children with chronic health conditions, children of American Indian or Alaskan Native heritage, health care workers, pregnant women, women who may become pregnant or are breastfeeding and people who have contact with children in high-risk populations. The U.S. Centers for Disease Control and Prevention estimates that between 135 million and 139 million doses of vaccine will be manufactured for the 2013-14 influenza season. Read more on influenza.
HUD: $37M to Oklahoma for ‘Unmet Needs’ of Disaster Recovery
The U.S. Department of Housing and Urban Development (HUD) has allocated approximately $37 million in disaster recovery funds for the state of Oklahoma and the City of Moore, Okla., which were severely damaged by extreme storms—including an EF5 tornado—on May 20. Dozens were killed and more than $1 billion in property damage was caused. The grants are part of HUD’s Community development Block Grant Program, which supports long-term disaster recovery efforts in places of “unmet need.” “The May storms cost the lives of dozens of Oklahomans and over $1 billion in property damage. “We are steadily rebuilding, but many families are still struggling to get back on their feet,” said Oklahoma Governor Mary Fallin. “The disaster relief grants provided by HUD—along with continued work from state and local governments and non-profits—will make a big difference in the lives of those affected by this year’s tornadoes. They will be particularly helpful as we work to provide assistance to low income Oklahomans, many of whom are uninsured.” About $26.3 million of the funds will go toward Moore, with the rest going toward the state.

Boys Faced Higher Death Risk than Girls from Multiple Causes
Boys on average face a higher risk of death than girls—not just from traumatic events such as accidents, homicides and suicides, but also from cancers and diseases of the heart, lungs and nervous system. The study found that from 1999 to 2008 there were about 76,700 more deaths among boys than girls, and that boys from infancy to age 20 were 44 percent more likely to die. The findings appear in the latest edition of the journal Pediatrics. The findings are not entirely surprising, as past research has indicated that girls have a certain survival advantage and experts already knew that boys are at increased risk of developing certain chronic health conditions. Still, the question is why. "This could be a story of resilience and ability to overcome," said study author Chris Feudtner, MD, a pediatrician at the Children's Hospital of Philadelphia. "Maybe there's some robustness factor that males are missing." Feudtner said that learning why boys faced these higher risks—and for chronic diseases in particular—could help health care experts better understand and treat the conditions. Read more on mortality.
Self-monitoring Tied to Improved Blood Pressure
Self-monitoring of blood pressure is tied to lower blood pressure in people with hypertension, according to a new study in the Annals of Internal Medicine. The study found the strategy was most successful when combined with providing extra resources to patients, such as online materials. Hayden Bosworth, of the Duke University Medical Center and the Durham Veterans Affairs Medical Center in North Carolina, said self-monitoring can provide more accurate results because the patients are not feeling the stress that they would in the doctor’s office. It also provides more in terms of actual data, which helps physicians to better determine treatments, and helps patients take a constant ownership of their health. "If you eat five ham biscuits for breakfast … you can see the implications of that through your blood pressure in monitoring that relatively quickly, as well as if you exercise," said Bosworth to Reuters. "It's no different than tracking your own weight. You need to know, on a daily basis, how you're doing, what sets it off and are you going too high or too low." Read more on heart health.
New Association Represents Accredited Public Health Schools and Programs
The new Association of Schools and Programs of Public Health (ASPPH), which represents schools and programs of public health accredited by the Council on Education for Public Health (CEPH), officially launched on August 1. “This is a seminal moment in CEPH-accredited public health education,” says Dr. Harrison Spencer, president and CEO of ASPPH. “Representing both accredited schools and programs of public health gives the association and our members an opportunity to strengthen public health education, research, teaching, and practice.” The U.S. Department of Education has recognized CEPH as the accrediting body for public health schools and programs, which helps ensure the quality education and training necessary to prepare graduates for the future of public health work.

Flu Vaccine for All Four Seasonal Strains Approved for Shipment
The first vaccine to protect against all four strains of seasonal influenza has been approved for shipment for the U.S. Food and Drug Administration. GlaxoSmithKline’s Fluarix Quadrivalent vaccine was approved late last year for use in adults and children aged 3 and older, but regulations require flu vaccines to be approved before they are shipped to health care providers each season. The company estimates it will ship approximately 22 to 24 million doses globally, with 10 million doses in the United States. The U.S. Centers for Disease Control and Prevention has ordered more than 4 million doses. Read more on influenza.
FDA Uses ‘Substantial Equivalence’ Standard to Authorize Two New Tobacco Products, Deny Four Others
The U.S. Food and Drug Administration (FDA) has, for the first time, utilized the substantial equivalence pathway to deny the marketing of four new tobacco products and allow the marketing of two new ones. FDA was granted the authority under the Family Smoking Prevention and Tobacco Control Act of 2009. Manufacturers can seek approval of new products by showing they are substantially equivalent to other tobacco products currently on the market. “Today’s decisions are just the first of many forthcoming product review actions to be issued,” said Mitch Zeller, JD, director of the FDA's Center for Tobacco Products. “The FDA is committed to making science-based decisions on all product applications and providing the agency’s scientific rationale behind its actions to ensure the most transparent and efficient process possible for all involved parties, according to the law.” Read more on tobacco.
Daily Contacts Leave Kids, Teachers, Health Care Workers at Highest Flu Risk
Children, teachers and health care workers are at the greatest risk of catching and transmitting influenza, according to a new study in the journal Proceedings of the Royal Society B. The study utilizes online and mail surveys to analyze the daily social contacts of more than 5,000 people. "People working as teachers or health professionals are no doubt already aware that they have higher risks of picking up bugs like colds and flu. But before this study there was very little data mapping out the contact patterns humans have in their daily life," said Leon Danon, from the Mathematics Institute at the University of Warwick, England, in a release. "By quantifying those social interactions, we can better predict the risks of contracting and spreading infections and ultimately better target epidemic control measures in the case of pandemic flu, for example.” Researchers recommend the people at greatest risk be especially careful to wash their hands with soap and water; maintain clean surfaces; and use tissues when needed.

New Study Paints Larger Picture on Adolescent Concussions
New research on youth concussions gives a broader picture of the “silent epidemic” and shows that kids who smoke and drink are at increased risk. The study appears in the Journal of the American Medical Association. Canadian researchers found that about 20 percent of approximately 9,000 Ontario adolescents who were surveyed had suffered from a concussion. About half were related to sports, but they also found that teens who smoked marijuana or consumed alcohol were at three-to-five times higher risk. "This is the first study I'm aware of that looked at the general population," said Kenneth Podell, co-director of the Methodist Concussion Center at the Methodist Hospital System in Houston. U.S. emergency departments treat about 173,000 adolescents annually for traumatic brain injuries, which includes concussions, according to the U.S. Centers for Disease Control and Prevention.

HHS Launches Redesigned Website
The U.S. Department of Health and Human Services (HHS) has launched a redesigned website to make it easier for public health officials, health care experts and consumers navigate the agency’s diverse collection of resources. The new site emphasizes direct access to the latest news and top areas of interest—including priority websites manages by the large agency—while also highlighting ways to connect with HHS on social media, including Twitter and Facebook.

Overuse, Unsafe Methods Increase Serious Injury Risk in Youth Baseball
Non-adherence to pitch counts and general overuse has helped lead to a dramatic increase in youth baseball throwing injuries requiring surgery. The injuries now occur 16 times more often as they did only 30 years ago, according to Joseph Guettler, MD, an orthopedic surgeon and sports medicine specialist with the Beaumont Health System in Royal Oak, Mich. Factors include pitching more than one game per day, pitching on back-to-back days, not utilizing pitch counts and throwing curve balls before high school. "It became very clear that dangerous pitching behavior is occurring among pitchers as young as Little League all the way through their high school years,” said Guettler. “And, the blame doesn't usually lie with the leagues or coaches. Most were found to be adhering to nationally recognized guidelines for pitch limits and rest. It seems much of the blame lies with behavior of parents and their kids.” To avoid injuries, he recommends the “Rule of Ones,” which limits how often a kid pitches, how many positions they play, how many teams that play for and other factors that increase serious injury risk.

CDC Recommends FluBlok Influenza Vaccine for People with Egg Allergies
In a unanimous vote, the U.S. Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices has recommended FluBlok for the upcoming influenza season for people ages 18-49 who suffer from egg allergies. The production of FluBok, which was licensed by the U.S. Food and Drug Administration in January of this year, does not utilize the influenza virus or chicken eggs. Read more on influenza.
