Vitamin D Deficiency Can Lead to Increased Allergies

Food allergy, a serious and potentially life-threatening medical condition, affects a growing number of Americans. According to Food Allergy Research and Education (FARE), 1 in 13 children now has a food allergy and every three minutes a food reaction sends someone to the emergency room.1

Food allergies are also estimated to affect nearly 4 percent of adults, according to the U.S. Centers for Disease Control and Prevention (CDC).2 While they are most common in babies and children, food allergies can develop at any age. Adults may even develop an allergy to foods they’ve previously eaten for years with no problem.

More than 170 foods have been reported to cause allergic reactions, but the eight major food allergens include milk, eggs, peanuts and tree nuts, wheat, soy and fish.3 However, as evidenced by the British teenager who recently died after eating sesame,4 this seed is also an emerging concern. The number of hospitalizations for food allergies have tripled from the late 1990s to the mid-2000s.5

Nearly 40 percent of children with food allergies have experienced a severe reaction, such as anaphylaxis. Typical food allergy symptoms may begin with hives, rash, nausea, vomiting or diarrhea. This may be followed by coughing and wheezing. In severe cases, anaphylaxis can occur, which is when your throat swells and you may not be able to breathe.

The rising prevalence of food allergies has been particularly noticeable in the West, where there is also rising numbers suffering vitamin D deficiency.6 Nearly 7 percent of children in the U.K. and 9 percent of those in Australia suffer from food allergies.7

Is It a Food Allergy or Intolerance?

Sensitivities and food reactions are often mistaken for allergies. A true food allergy is mediated by the immune system and triggered by an antibody reaction to a protein in a specific food or drink. While most develop during childhood, the most common allergies known to develop in adults are allergies to shellfish, tree nuts and peanuts.8

Food sensitivity, also called food intolerance, is an unpleasant — usually gastrointestinal — reaction to something you’ve swallowed, but is not mediated by your immune system.9 For instance, a true allergy to milk is different from lactose intolerance, which triggers gastrointestinal symptoms from an inability to digest proteins in the milk.10

Type 1 food allergies involve immunoglobulin-e (IgE), an antibody in the blood and mast cells found in all body tissues. Food allergies mediated by IgE are triggered after you’ve eaten a food for the first time, after which cells produce IgE for the part of the food triggering the allergic reaction, called an allergen.

IgE is released and attaches to the surface of mast cells. This process sets the stage for the next time you’ve eaten a food with the specific allergen. The protein interacts with IgE and triggers mast cells to release histamine. Since some food allergens are not broken down by heat or stomach acid, they cross immediately into your bloodstream and may cause reactions throughout your body.11

IgE reactions may start with itchiness in your mouth, followed by symptoms of vomiting, diarrhea and stomach pain. If the allergen reaches your blood, it can trigger a drop in blood pressure; in your skin you may experience hives or eczema; and in the lungs it may trigger wheezing. Each of these reactions can take a few minutes or a couple of hours to develop and signal an immediate food allergy.

A second type of food allergy, Type 3, also called delayed food allergy, is mediated by immunoglobulin-g (IgG). These reactions occur hours and possibly even days following your exposure to the allergen. Individuals who suffer from Type 3 food allergies are often allergic to more than two types of food, and larger amounts of food over multiple meals are needed to provoke this reaction.12

You may experience some of the same types of symptoms, making it difficult to distinguish between an IgE and an IgG response. Foods triggering an IgG response are often favorite foods eaten in larger amounts. IgG responses do not typically show up on a skin test.

Rising Prevalence of Allergies Corresponds to Increasing Vitamin D Deficiency

Food allergies associated with IgE affects 3 percent of the population, with severe effects on daily life. Manifestations of the allergy are not only gastrointestinal, but also affect other organ systems and may lead to an anaphylactic response.13

While vitamin D also has known effects on lung and immune system development, as well as support of the immune system after birth,14 including asthma and allergic responses, it is also significant in the regulation of IgE.

The increase in allergies and sensitivities to foods is likely related to environmental factors and Western lifestyles. Developing nations have lower rates of allergic responses, and individuals with allergies are likely to live in urban rather than rural areas.

Although there is no single explanation for the rise in prevalence, one significant factor is the overwhelming vitamin D deficiency suffered by those who live in urban areas.15

The link between vitamin D deficiency, which has almost doubled in just over a decade in the U.S.,16 and poor regulation of IgE responses, may be a significant factor. Both of these play a role in the development, severity and course of allergic diseases, and help explain, at least in part, why so many adults are now developing food allergies.

Australia has the highest rate of confirmed food allergies, with one study finding 9 percent of 1-year-olds suffering from egg allergy.17 Australia initiated one of their most successful health campaigns to increase use of sun screen in 1981 with the slogan “Slip! Slop! Slap!”18

At the time, the campaign was aimed at lowering melanoma rates, which the government believed was the result of spending too much time in the sun.

Today, nearly 25 percent of Australia’s population is deficient in vitamin D. Despite these numbers, Choosing Wisely Australia, an initiative of NPS MedicineWise,19 does not recommend having routine testing for vitamin D unless you’re specifically at risk, including those who:20





Have a health condition affecting vitamin D absorption from their diet

Cover their body completely when outside

Are a baby of a vitamin D deficient mother

Spend the majority of their day indoors

Take medications affecting vitamin D

Avoid the sun completely

Have naturally dark skin

Suffer obesity

Considering the prevalence of vitamin D deficiency, I strongly recommend getting your vitamin D level tested regardless of whether you fit into a high-risk category or not, and to make sure you’re actually within the ideal range of 60 to 80 ng/mL, and if below 60 ng/mL, take proactive steps to optimize your level. The fact of the matter is, most people are at high risk for vitamin D deficiency these days.

Early Exposure to Allergens May Reduce Allergy Risk

In addition to vitamin D deficiency, a theory of dual allergen exposure may also explain the rise in pediatric food allergies. This was the basis for the LEAP study from King’s College London, in which they evaluated how early exposure to peanuts may affect the development of a peanut allergy.21

The prevalence of peanut allergy in children has doubled in the past 10 years in countries where parents are advised to avoid exposure to peanuts during pregnancy, lactation and infancy.

The researchers randomly assigned 640 infants, 4 to 11 months old, with a history of severe eczema, egg allergy or both, to either eat or avoid peanuts until they were 60 months old. The children were assigned to groups based on preexisting sensitivity to peanut extract, determined by a skin-prick test.

Of the 98 participants treated who initially had a positive peanut allergy test, 35 percent of those who avoided peanuts had a peanut allergy at 60 months, compared to just 10 percent of those who consumed peanuts. Dr. Gideon Lack, lead investigator for the study, commented:22

“For decades allergists have been recommending that young infants avoid consuming allergenic foods such as peanut to prevent food allergies. Our findings suggest that this advice was incorrect and may have contributed to the rise in the peanut and other food allergies.”

These results have been validated in subsequent studies, finding late introduction of fish and eggs is associated with an increased risk of allergy development.23 A metadata analysis from the Imperial College London, which evaluated 146 studies with over 200,000 children, also concluded that feeding egg between the ages of 4 and 6 months may reduce the child’s risk of developing an egg allergy.24

Other Health Benefits of Vitamin D Optimization

Vitamin D deficiency has become so widespread it’s been called a pandemic by a Harvard Medical School researcher.25 The short list of health benefits attributed to vitamin D optimization include improving your immune system, strengthening muscles, bones and teeth and improving your cardiovascular health.

Over the past decades, thousands of studies have evaluated the benefits of vitamin D and have linked low levels to a host of chronic health conditions. In fact, this site was one of the leaders to help catalyze interest in vitamin D over 15 years ago.

Unfortunately, some studies claim supplementation at amounts over 4,000 IUs/day may lead to health problems. Research by GrassrootsHealth negates such concerns, showing toxicity is not an issue until you hit 30,000 IUs a day.26

What’s more, the recommended vitamin D level and dosage established by the National Academy of Medicine is actually the result of a mathematical error that has never been corrected. You can read more about this in my previous article, “Are Americans Really Getting Too Much Vitamin D? A Critical Look at Recent Media Warnings.”

There is a long list of studies confirming the correlation between vitamin D status and cancer risk. Maintaining sufficient levels of vitamin D also helps to lower all-cause mortality and risk of Type 2 diabetes.

During pregnancy, optimal levels of vitamin D help to reduce the percentage of preterm birth, and subsequently higher risks of ADHD, asthma, autism and vision problems associated with early birth. Low levels of vitamin D are also associated with depression, metabolic syndrome,27 cardiovascular disease28 and lung disease.29

Maintain Healthy Levels to Help Prevent Disease

My recommendation is to get your vitamin D level tested twice a year, when your level is likely to be at its lowest (midwinter) and highest (midsummer). This is particularly important if you’re pregnant, planning a pregnancy or if you have cancer.

Research30 suggests it may require 9,600 IUs of vitamin D per day to get a majority (97.5 percent) of the population to reach 40 ng/mL, but individual requirements can vary widely. If you’ve been taking a certain amount of vitamin D3 for a number of months and retesting reveals you’re still not within the recommended range, then you know you need to increase your dosage.

Over time, with continued testing, you’ll find your individual sweet spot based on your usual safe sun exposure and have a good idea of how much supplementation you need to maintain a year-round level of 60 to 80 ng/mL, which research suggests is the ideal range for optimal health and disease prevention.

GrassrootsHealth offers vitamin D testing through its D*Action study, and has an online vitamin D calculator you can use to estimate your vitamin D3 dosage once you know your current serum level.

The Synergism Between Vitamin D3, Magnesium, Calcium and Vitamin K2

Pamela Lutsey, public health researcher at the University of Minnesota, points out excessive vitamin D may cause over absorption of calcium, which in turn may result in calcium deposits in your heart and kidneys. Indeed, it is important to maintain not only the proper balance of vitamin D and calcium, but also magnesium and vitamin K2.

Lack of balance between these four nutrients is why calcium supplements have become associated with increased risk of heart attack and stroke, and why some experience symptoms of “vitamin D toxicity.” I use quotation marks here, because the problem is not so much excess vitamin D as it is a lack of vitamin K2.

Part of the explanation for these adverse side effects is that vitamin K2 is what keeps calcium in its appropriate place. If you’re K2 deficient, added calcium can cause more problems than it solves, by accumulating in the wrong places. Similarly, taking megadoses of vitamin D supplements without sufficient amounts of K2 can lead to inappropriate calcification, which is what Lutsey is suggesting.

While the optimal ratios between vitamin D and vitamin K2 have yet to be established, Dr. Kate Rheaume-Bleue (whom I’ve interviewed on this topic) suggests for every 1,000 IUs of vitamin D you take, you may benefit from about 100 micrograms (mcg) of K2, and perhaps as much as 150 to 200 mcg.

Maintaining an appropriate calcium-to-magnesium ratio is also important, as magnesium helps keep calcium in your cells so they can function better. Historically, mankind ate a diet with a calcium-magnesium ratio of 1-to-1,31 but Americans tend to have a higher calcium-to-magnesium ratio in their diet, averaging about 3.5-to-1.

Magnesium and vitamin K2 also complement each other, as magnesium helps lower blood pressure, which is an important component of heart disease. So, anytime you’re taking magnesium, calcium or vitamin D3, remember to take all the others into consideration as well, as they all work synergistically with each other.

Sweet! Here are 7 reasons to eat sweet potatoes

Editor

Published

on

By

(Natural News) Sweet potatoes may not be as popular as regular potatoes, which is too bad — since they’re packed with vitamins and minerals. One cup of sweet potatoes can provide more than 100 percent of the daily value of vitamin A. It’s also rich in vitamin C, dietary fiber, and manganese. Both purple and orange varieties contain antioxidants that can protect the body from damage caused by free radicals.

Eating sweet potatoes is beneficial for your health

Sweet potatoes are brimming with micronutrients and antioxidants —  making them useful to your health. Below is a list of reasons why you should incorporate sweet potatoes into your diet.

They improve brain function

The purple variety of sweet potato contains anthocyanins. Anthocyanins are known for their anti-inflammatory properties. Studies have revealed that anthocyanins are effective at improving cognitive function. Moreover, the results suggest that purple yams can help protect against memory loss. Antioxidants from the purple variety safeguard the brain against damage from free radicals and inflammation.

They aid digestion

Sweet potatoes are rich in dietary fiber. This macronutrient prevents constipation, diarrhea, and bloating by adding bulk and drawing water to the stool. In addition, fiber keeps a healthy balance in the gut by promoting the growth of good bacteria.

They slow down aging

The beta-carotene in orange sweet potatoes can help reduce damage caused by prolonged sun exposure. This is especially true for people diagnosed with erythropoietic protoporphyria and other photosensitive diseases. Sweet potatoes also contain antioxidants that protect against free radical damage. Free radicals are not only linked to diseases but also premature aging.

They boost the immune system

Orange and purple sweet potatoes are loaded with a good number of antioxidants that help protect the body from harmful molecules that cause inflammation and damage DNA. This, in turn, protects the body from chronic diseases like cancer and heart disease.

They can prevent cancer

Eating sweet potatoes can help protect against various types of cancers. The compounds in sweet potatoes restrict the development of cancer cells. Test tube studies have shown that anthocyanins can prevent cancers in the bladder, breast, colon, and stomach.

They lower blood sugar

Despite its relatively high glycemic index, studies have shown that the regular intake of sweet potatoes can help lower blood sugar, thanks to the presence of dietary fiber. While fiber falls under carbohydrates, it is digested differently, compared to starchy and sugary forms of carbohydrates. Interestingly, insulin doesn’t process fiber (unlike other types which get turned into glucose), and it only passes through the digestive tract.

They promote healthy vision

Orange sweet potatoes are rich in a compound called beta-carotene, an antioxidant which transforms into vitamin A in the body. Adequate intake of vitamin A promotes eye health. Conversely, deficiencies in vitamin A have been linked to a particular type of blindness called xerophthalmia.

Sweet potatoes are easy to incorporate into your everyday meals. They are best prepared boiled but can also be baked, roasted, or steamed — they can even replace other carbohydrates such as rice, potatoes, and toast.

Frostbite: What it is and how to identify, treat it

Editor

Published

on

By

Manitoba’s temperature has plummeted to its coldest level this season, triggering warnings about the extreme risk of frostbite.

Oh, we know it’s cold. We can feel Jack Frost nipping at our noses. But what about when he gnaws a little harder — what exactly does “frostbite” mean?

People tend to underestimate the potential for severe injuries in the cold, says the Winnipeg Regional Health Authority. We laugh off the sting of the deep freeze, rub our hands back from the brink of numbness and wear our survival proudly like a badge.

That’s because, in most cases, frostbite can be treated fairly easily, with no long-term effects.

But it can also lead to serious injury, including permanent numbness or tingling, joint stiffness, or muscle weakness. In extreme cases, it can lead to amputation.

Bitter cold can cause frostbite in just minutes. Here’s how to recognize the warning signs and treat them. 0:59

Here’s a guide to identifying the first signs, how to treat them, and when to seek medical help.

What is frostbite and frostnip?

Frostbite is defined as bodily injury caused by freezing that results in loss of feeling and colour in affected areas. It most often affects the nose, ears, cheeks, chin, fingers or toes — those areas most often exposed to the air.

Cooling of the body causes a narrowing of the blood vessels, slowing blood flow. In temperatures below –4 C, ice crystals can form in the skin and the tissue just below it.

Frostnip most commonly affects the hands and feet. It initially causes cold, burning pain, with the area affected becoming blanched. It is easy to treat and with rewarming, the area becomes reddened.

Frostbite is the acute version of frostnip, when the soft tissue actually freezes. The risk is particularly dangerous on days with a high wind chill factor. If not quickly and properly treated, it can lead to the loss of tissues or even limbs. 

Signs of frostbite

Health officials call them the four P’s:

  • Pink: Skin appears reddish in colour, and this is usually the first sign.
  • Pain: The cold becomes painful on skin.
  • Patches: White, waxy-feeling patches show when skin is dying.
  • Prickles: Affected areas feel numb or have reduced sensation.

Symptoms can also include:

  • Reduced body temperature.
  • Swelling.
  • Blisters.
  • Areas that are initially cold, hard to the touch.

Take quick action

If you do get frostbite, it is important to take quick action.

  • Most cases of frostbite can be treated by heating the exposed area in warm (not hot) water.
  • Immersion in warm water should continue for 20-30 minutes until the exposed area starts to turn pink, indicating the return of blood circulation.
  • Use a warm, wet washcloth on frostbitten nose or earlobes.
  • If you don’t have access to warm water, underarms are a good place to warm frostbitten fingers. For feet, put them against a warm person’s skin.
  • Drink hot fluids such as hot chocolate, coffee or tea when warming.
  • Rest affected limbs and avoid irritation to the skin.
  • E​levate the affected limb once it is rewarmed.

Rewarming can take up to an hour and can be painful, especially near the end of the process as circulation returns. Acetaminophen or ibuprofen may help with the discomfort.

Do not …

There are a number of things you should avoid:

  • Do not warm the area with dry heat, such as a heating pad, heat lamp or electric heater, because frostbitten skin is easily burned.
  • Do not rub or massage affected areas. This can cause more damage.
  • Do not drink alcohol.
  • Do not walk on your feet or toes if they are frozen.
  • Do not break blisters.

Seek immediate medical attention

While you can treat frostbite yourself if the symptoms are minor — the skin is red, there is tingling — you should seek immediate medical attention at an emergency department if:

  • The exposed skin is blackened.
  • You see white-coloured or grey-coloured patches.
  • There is severe pain or the area is completely numb.
  • The skin feels unusually firm and is not sensitive to touch after one hour of rewarming.
  • There are large areas of blistering.
  • There is a bluish discolouration that does not resolve with rewarming.

Be prepared

The best way to avoid frostbite is to be prepared for the weather in the first place.

Wear several loose layers of clothing rather than a single, thick layer to provide good insulation and keep moisture away from your skin.

The outer garment should breathe but be waterproof and windproof, with an inner thermal layer. Retain body heat with a hat and scarf. Mittens are warmer than gloves because they keep the fingers together.

Be sure your clothing protects your head, ears, nose, hands and feet, especially for children.

Wind chill and frostbite rates

Wind chill: 0 to –9.
Frostbite risk: Low.

Wind chill: –28 to –39.
Frostbite risk: Moderate.

Exposed skin can freeze in 10-30 minutes

Wind chill: –40 to –47.
Frostbite risk: High.

Exposed skin can freeze in five to 10 minutes.

Wind chill: –48 to –54.
Frostbite risk: Very High.

Exposed skin can freeze in two to five minutes.

Wind chill: –55 and lower.
Frostbite risk: Extremely High.

Exposed skin can freeze in less than two minutes.
 

NOTE: In sustained winds over 50 km/h, frostbite can occur faster than indicated.

Awkward Flu Jabs Attempted at Golden Globes

Editor

Published

on

By

In what can only be described as a new level of propaganda, hosts Andy Samberg and Sandra Oh featured a flu shot stunt during the 76th Golden Globe Awards ceremony. They told the audience to roll up their sleeves, as they would all be getting flu shots, while people in white coats stormed down the aisles, syringes in hand.

Most of the audience looked thoroughly uneasy at the prospect of having a stranger stick them with a needle in the middle of an awards show. But perhaps the worst part of the scene was when Samberg added that anti-vaxxers could put a napkin over their head if they wanted to be skipped, basically suggesting that anyone opposed to a flu shot deserved to be branded with a proverbial scarlet letter.

The flu shots, for the record, were reportedly fake,1 nothing more than a bizarre gag that left many people stunned by the Globe’s poor taste in turning a serious medical choice into a publicity gimmick.

Flu Shot Stunt Reeks of Desperation

Whoever came up with the idea to turn the Golden Globes into a platform for a public health message probably thought it was ingenious, but the stunt only serves as a seemingly desperate attempt to make flu shots relevant and in vogue. During the 2017 to 2018 flu season, only 37 percent of U.S. adults received a flu shot, a 6 percent drop from the prior season.2

“To improve flu vaccination coverage for the 2018-19 flu season, health care providers are encouraged to strongly recommend and offer flu vaccination to all of their patients,” the U.S. Centers for Disease Control and Prevention (CDC) wrote. “People not visiting a provider during the flu season have many convenient places they can go for a flu vaccination.”3

Yet, perhaps the decline in people choosing to get vaccinated has nothing to do with convenience and everything to do with their dismal rates of efficacy. In the decade between 2005 and 2015, the influenza vaccine was less than 50 percent effective more than half of the time.4

The 2017/2018 flu vaccine was a perfect example of this trend. The overall adjusted vaccine effectiveness against influenza A and B virus infection was just 36 percent.5

Health officials blamed the flu season’s severity on the dip in vaccination rates, but as Dr. Paul Auwaerter, clinical director of the division of infectious diseases at Johns Hopkins University School of Medicine, told USA Today, “[I]t is also true that the vaccine was not as well matched against the strains that circulated.”6

But bringing flu shots to the Golden Globes, and calling out “anti-vaxxers,” is nothing more than “medical care, by shame,” noted Dr. Don Harte, a chiropractic activist in California. “But it was entertaining, in a very weird way, including the shock and disgust of some of the intended victims, notably [Willem Dafoe],” he said, adding:7

“This Hollywood publicity stunt for the flu vaccine is one of the stupidest things I’ve ever seen from celebrities. But it does go with the flu shot itself, which is, perhaps, the stupidest of all the vaccines available.”

Did 80,000 People Really Die From the Flu Last Year?

The CDC reported that 79,400 people died from influenza during the 2017/2018 season, which they said “serves as a reminder of how severe seasonal influenza can be.”8 It’s important to remember, however, that the 80,000 deaths figure being widely reported in the media is not actually all “flu deaths.”

According to the CDC, “We look at death certificates that have pneumonia or influenza causes (P&I), other respiratory and circulatory causes (R&C), or other nonrespiratory, noncirculatory causes of death, because deaths related to flu may not have influenza listed as a cause of death.”9

As for why the CDC doesn’t base flu mortality estimates only on death certificates that list influenza, they noted, “Seasonal influenza may lead to death from other causes, such as pneumonia, congestive heart failure or chronic obstructive pulmonary disease … Additionally, some deaths — particularly among the elderly — are associated with secondary complications of seasonal influenza (including bacterial pneumonias).”10

In other words, “flu deaths” are not just deaths directly caused by the influenza virus, but also secondary infections such as pneumonia and other respiratory diseases, as well as sepsis.11

According to the CDC, most of the deaths occurred among those aged 65 years and over, a population that may already have preexisting conditions that makes them more susceptible to infectious diseases. As Harte said of annual flu deaths, “[M]ost if not all, I would assume, are of people who are already in very bad shape.12

CDC Claims Flu Vaccine Reduces Flu Deaths in the Elderly — But Does It?

Since people aged 65 and over are those most at risk from flu complications and death, the CDC has been vocal in their claims that the flu shot significantly reduces flu-related deaths among this population. The research, however, says otherwise.

Research published in 2005 found no correlation between increased vaccination rates among the elderly and reduced mortality. According to the authors, “Because fewer than 10 percent of all winter deaths were attributable to influenza in any season, we conclude that observational studies substantially overestimate vaccination benefit.”13

A 2006 study also showed that even though seniors vaccinated against influenza had a 44 percent reduced risk of dying during flu season than unvaccinated seniors, those who were vaccinated were also 61 percent less like to die before the flu season ever started.14

This finding has since been attributed to a “healthy user effect,” which suggests that older people who get vaccinated against influenza are already healthier and, therefore, less likely to die anyway, whereas those who do not get the shot have suffered a decline in health in recent months.

Journalist Jeremy Hammond summed up the CDC’s continued spreading of misinformation regarding the flu vaccine’s effectiveness in the elderly, as they continue to claim it’s the best way to prevent the flu:15

[T]here is no good scientific evidence to support the CDC’s claim that the influenza vaccine reduces hospitalizations or deaths among the elderly.

The types of studies the CDC has relied on to support this claim have been thoroughly discredited due to their systemic ‘healthy user’ selection bias, and the mortality rate has observably increased along with the increase in vaccine uptake — which the CDC has encouraged with its unevidenced claims about the vaccine’s benefits, downplaying of its risks, and a marketing strategy of trying to frighten people into getting the flu shot for themselves and their family.”

Death of Vaccinated Child Blamed on Not Getting Second Dose

In January 2019, the state of Colorado reported the first child flu death of the 2018/2019 flu season — a child who had received influenza vaccination. But instead of highlighting the vaccine’s failure and clear limitations, the Colorado Department of Public Health and Environment blamed the death on the child being only “partially vaccinated.”

“It’s an unfortunate but important reminder of the importance of two doses of influenza vaccine for young children who are receiving influenza vaccine for the first time,” Dr. Rachel Herlihy, who is the state communicable disease epidemiologist, said in a news release.16 For those who aren’t aware, the CDC notes that one dose of flu shot may not be enough to protect against the flu. Instead, they state:17

“Children 6 months through 8 years getting vaccinated for the first time, and those who have only previously gotten one dose of vaccine, should get two doses of vaccine this season …

The first dose ‘primes’ the immune system; the second dose provides immune protection. Children who only get one dose but need two doses can have reduced or no protection from a single dose of flu vaccine.”

Not only may the flu vaccine fail to provide protection against the flu, but many people are not aware that other types of viruses are responsible for about 80 percent of all respiratory infections during any given flu season.18 The flu vaccine does not protect against or prevent any of these other types of respiratory infections causing influenza-like illness (ILI) symptoms.

The chance of contracting actual type A or B influenza, caused by one of the three or four influenza virus strains included in the vaccine, is much lower compared to getting sick with another type of viral or bacterial infection during the flu season.

Does Flu Vaccine Increase the Risk of Influenza Infection, Contribute to Vaccine Shedding?

There are serious adverse effects that can come along with annual flu vaccination, including potentially lifelong side effects such as Guillain Barré syndrome and chronic shoulder injury related to vaccine administration (SIRVA). They may also increase your risk of contracting more serious flu infections, as research suggests those who have been vaccinated annually may be less protected than those with no prior flu vaccination history.19

Research presented at the 105th International Conference of the American Thoracic Society in San Diego also revealed that children who get seasonal flu shots are more at risk of hospitalization than children who do not. Children who had received the flu vaccine had three times the risk of hospitalization as children who had not. Among children with asthma, the risk was even higher.20

There’s also the potential for vaccine shedding, which has taken on renewed importance with the reintroduction of the live virus vaccine FluMist during the 2018/2019 season. While the CDC states that the live flu virus in FluMist is too weak to actually give recipients the flu, research has raised some serious doubts that this is the case.

One recent study revealed not only that influenza virus may be spread via simple breathing (i.e., no sneezing or coughing required) but also that repeated vaccination increases the amount of virus released into the air.21

MedImmune, the company that developed FluMist, is aware that the vaccine sheds vaccine-strain virus. In its prescribing information, they describe a study on the transmission of vaccine-strain viruses from vaccinated children to nonvaccinated children in a day care setting.

In 80 percent of the FluMist recipients, at least one vaccine-strain virus was isolated anywhere from one to 21 days following vaccination. They further noted, “One placebo subject had mild symptomatic Type B virus infection confirmed as a transmitted vaccine virus by a FluMist recipient in the same playgroup.”22

Are There Other Ways to Stay Healthy During Flu Season?

Contrary to the CDC’s and Golden Globe’s claims that flu vaccinations are a great way to prevent flu, other methods exist to help you stay healthy during the flu season and all year, and they’re far safer than annual flu vaccination. Vitamin D testing and optimization have been shown to cut your risk of respiratory infections, including colds and flu, in half if you are vitamin D deficient, for instance.23,24

In my view, optimizing your vitamin D levels is one of the absolute best respiratory illness prevention and optimal health strategies available. Influenza has also been treated with high-dose vitamin C,25 and taking zinc lozenges at the first sign of respiratory illness can also be helpful.

Following other basic tenets of health, like eating right, getting sound sleep, exercising and addressing stress are also important, as is regularly washing your hands.
