What About Covid Vaccines And Food Allergy
There is still much to learn about the COVID-19 vaccines. To date, the CDC notes only two allergies, both of them involving additives. If you have an allergy to the food additive polysorbate, you should avoid the Johnson & Johnson vaccine. If you are allergic to polyethylene glycol, you should avoid any of the mRNA vaccines, including the Moderna and Pfizer vaccines.
Food Allergies Are A Growing Problem
Millions of Americans have food allergies, including about 1 in 13 children, and the numbers have increased in recent years. Peanut allergy is the most common one among children, and among the most dangerous. Accidental exposures are frequent, with about 1 in 4 affected children winding up in the emergency room every year.
What happens: The immune system overreacts to the food by triggering an inflammatory cascade. On average, children can experience hives, wheezing or worse from just a 30th of a single peanut, sometimes even less, said Dr. Hemant Sharma, who leads oral treatment studies at Childrens National Hospital in Washington.
Until now, all doctors could advise was to read food labels and avoid anything that might contain hidden peanuts. Decades ago, attempts at shots were deemed too risky for food allergies. Then, in 2006, researchers at Duke University and the University of Arkansas reported tantalizing signs that swallowed treatments might work instead.
How Can I Take Care Of Myself If I Have A Peanut Allergy
If you have a peanut allergy, you need to pay close attention to what you eat. Food manufacturers must clearly state on their ingredient label whether a food contains peanuts.
Prepackaged foods that dont contain peanuts can be contaminated during the manufacturing process. Watch for phrases like may contain peanuts and made in a factory on machinery that also may have been used to process peanut products.
When you go out to eat, ask questions about ingredients. For example, peanut butter may be in certain marinades or sauces. Ice cream or yogurt shops could be places of accidental exposure because peanuts are common ice cream toppings.

Why The Most Dreaded Injection Is Called The ‘peanut Butter’ Shot
Every recruit, in the first few weeks of boot camp, will get in a line during their medical evaluations and get stuck in the arm with all sorts of needles and have thermometers shoved into some uncomfortable places.
Welcome to the military!
Out of all the medications recruits get injected with throughout their processing week, none of them are as feared as the almighty “peanut butter” shot.
While these peanut butter shots are awesome, the ones we get in boot camp are far from exciting.
The “peanut butter” shot, in the military, is a slang term for the famous bicillin vaccination every recruit receives unless they have an allergy and can prove it.
But if you can’t, you’re in for an experience of a lifetime. You’ll be brought into an examination room, usually as a group, and be told to drop your trousers past one of your butt cheeks and bend over.
Once the recruit has assumed their most vulnerable position, the medical staff will attach a long and thick needle to a pre-filled vial of bicillin.
Since bicillin kills off a variety of bacteria strands in one shot, it’s given to nearly every recruit.
Now, once the medical staff injects the recruits in their butt cheek, the pain hits them like a bolt of electricity. The thick liquid begins to pour into the muscle, but it doesn’t spread as fast as you might think.

Implementing A Program: Cost Training Risks Limitations
Incorporating oral immunotherapy into a clinical practice requires significant resources dedicated to staffing, training, and physical space. Due to the extended course of treatment, a practice interested in implementing oral immunotherapy would need to ensure that adequate clinical support staff are available for preparing materials, administering doses, monitoring, and treating reactions if they occur.
The initial dose-escalation visit can last 5 to 6 hours. During this time, doses are given every 20 minutes, and clinicians monitor and assess the patientâs vital signs, making it a time-intensive first day.
Subsequent visits in the up-dosing phase involve preparing materials, administering 1 dose, and monitoring for a minimum of 1 hour. As a clinical practice with oral immunotherapy grows, these subsequent visits would require a structure similar to the established practice of incorporating allergen inhalant immunotherapy in allergy practices, but more allergic reactions are expected with oral immunotherapy.
Providers and clinical support staff should have appropriate training for administering oral immunotherapy and managing allergic reactions. Practices must be equipped with medications needed to treat anaphylaxis, oxygen, and basic resuscitation supplies.

Important: OIT should only be done under a doctors supervision do NOT try OIT on your own.
They’re Not Recommended For Everyone
Most adultsand children ages 5 and upcan get allergy shots. But if you or your child has severe, uncontrolled asthma, your doctor may recommend against them. “In our practice, if a patient’s asthma is flaring or even if they’re sick, we generally wait to give the shot until they’re feeling better,” says Dr. Dziadzio.
Women who become pregnant while in the maintenance phase of allergy shots can continue their treatment. But women shouldn’t start allergy shots for the first time, or increase their dosage, while pregnant.
Certain medicines, like beta blockers, can reduce the effectiveness of epinephrinethe lifesaving drug used to treat anaphylactic shock. Because anaphylaxis is a rare but serious risk for people getting allergy shots, they may not be recommended for people who take these drugs.

What Is Peanut Allergy
Peanut allergy is the most common food allergy in children under age 18 and the second-most common food allergy in adults. Peanut allergy is usually lifelong: only about 20 percent of children with peanut allergy outgrow it over time.¹
When a person with a peanut allergy is exposed to peanut, proteins in the peanut bind to specific IgE antibodies made by the persons immune system. Subsequent exposure to peanut protein, typically by oral ingestion, triggers the persons immune defenses, leading to reaction symptoms that can be mild or very severe.
Allergy to peanut is the only food allergy for which a treatment has been approved by the U.S. Food and Drug Administration Palforzia. There are other treatment protocols currently being used to improve an individuals tolerance to the peanut protein, such as peanut oral immunotherapy, but these are non-FDA approved.
Peanuts are not the same as tree nuts , which grow on trees. ² Peanuts grow underground and are part of a different plant family, the legumes. Other examples of legumes include beans, peas, lentils and soybeans. Being allergic to peanuts does not mean you have a greater chance of being allergic to another legume. However, allergy to lupine, another legume commonly used in vegan cooking, can occur in patients with peanut allergy.
Peanut allergies affect up to 2% of pediatric population, and many will carry this allergy into adulthood.³
Peanut Allergy: A New Medicine For Children May Offer Protection
- By Claire McCarthy, MD, Senior Faculty Editor, Harvard Health Publishing
Of all food allergies, which affect between 5% and 8% of US children, peanut allergy is the one most likely to cause anaphylaxis, a serious type of allergic reaction. For a child with a peanut allergy, eating one peanut can literally be fatal.
When you have an allergy, says Andrew MacGinnitie, MD, PhD, clinical director of the division of immunology at Boston Childrens Hospital, your body sees the thing you are allergic to as dangerous. So your immune system tries to protect you by causing hives, vomiting, and other symptoms.
The body does this by releasing histamine and other chemicals that are designed to help your body get rid of whatever is causing the allergic reaction. Hives increase blood flow to an area so that your immune system can get to work. Sneezing helps you get rid of pollen or cat hair in your nose. And vomiting helps get rid of whatever is in your stomach. The problem is that when the reaction is severe, with an outpouring of more of these chemicals than is needed, it can lead to trouble breathing and a dangerous drop in blood pressure. If untreated, this can lead to death.

What Are The Signs And Symptoms Of A Peanut Allergy
A peanut allergy may be mild or severe. Any of the following can develop minutes to hours after you eat peanut. Your reaction may change each time you are exposed.
- A rash, hives, or itching
- Nausea, vomiting, diarrhea, or blood in the bowel movements
- A runny or stuffy nose, cough, wheezing, or trouble breathing
- Itchy or watery eyes, swelling, or a hoarse voice
- Feeling lightheaded, or feeling that you may faint
Is There A Cure For Peanut Allergies
There is no cure for peanut allergies. But children can outgrow peanut allergies. As children get older, an allergist may perform another blood or skin test to measure a childs sensitivity to peanuts. If a peanut allergy appears to be decreasing, allergists may recommend an oral food test.
There are new treatments available called Oral Immunotherapy and early OIT. This is where carefully selected patients undergo therapy to help develop a tolerance to the food they have an allergy to. Palforzia®, a treatment for peanut allergies, is the first FDA approved treatment for food allergies. Although it doesn’t cure peanut allergies, it can make it possible for people to tolerate accidental peanut exposure without having a reaction.
If your child has a peanut allergy, it’s important to not give your child peanuts unless an allergist has directed you to do so.
As an adult, you can manage a peanut allergy by carefully avoiding peanuts. You may need to carry epinephrine if you have severe allergies that could lead to anaphylaxis.

What Age Should Children Undergo Peanut Oral Immunotherapy
Palforzia is currently prescribed for children ages 4-17. What about children ages 1-3? Its best to consult with a board-certified allergist who specializes in OIT.
The new IMPACT study suggests OIT could safely desensitize peanut-allergic children ages 1-3. It could also help some peanut-allergic children become non-allergic to peanuts. The National Institute of Allergy and Infectious Diseases funded the study.
The study involved 146 peanut-allergic children. They received either 2,000 milligrams of peanut protein per day or a placebo. After 2.5 years, the researchers found 71% of those who received OIT had become desensitized to peanuts. After three years, 20.8% of those who received peanut protein were in remission of peanut allergy.
The research suggests that if peanut OIT is started at ages 1-3, theres a chance of remission in some children. Doctors caution that more longer-term research needs to be done. Peanut OIT should not be considered a cure.
Important: do not try peanut OIT with a peanut-allergic child at home. There is a risk of a severe allergic reaction. Peanut OIT should only be done under the supervision of a doctor who specializes in the treatment.
Discovering His Food Allergies
When Noah was young, his parents werent even sure he had allergies. As a baby starting solid foods, Noah had an unusually negative reaction to peanut butter. It was nothing too dramatic, but enough that we didnt introduce it again, says Noahs dad, Craig.
The family didnt keep peanuts in the house, but they didnt completely avoid them either. The limited contact seemed to work Noah didnt have any noticeable allergic reactions for the next few years.
When Noah was about 3 years old, he had a serious allergic reaction after playing with a friends dog. That incident prompted his parents to get more information about his allergies. Tests at his local doctor’s office revealed Noah was allergic to peanuts, eggs, almonds and dog dander .
His parents began strict avoidance of those allergens from then on. But then came the fateful day in second grade when Noah accidently ate a piece of candy that contained peanuts. After his severe allergic reaction, his parents turned to CHOP for answers and possible treatments.
We chose CHOP based on its reputation as a great organization with a great mission and amazing people, Craig says.

How Do You Prepare For An Allergy Shot
Before you start allergy shots, youll need a full evaluation. The doctor needs to test your allergies to know exactly which substances to use in the shots.
Allergy testing usually consists of skin pricking. During a skin prick test, your doctor will prick the skin on your back or forearm with several types of allergens to determine which ones cause reactions.
A type of specialist known as an allergist or an immunologist will conduct all testing and treatment with allergy shots.
Once your doctor has identified your allergens, youll start receiving allergy shots. The process is broken down into two phases:
Antibody Injection Stops Peanut Allergy For 2 To 6 Weeks Study Shows
A Stanford-led pilot study has provided early evidence that an antibody is a safe, effective and rapid food allergy treatment.
One injection of an antibody treatment let people with severe peanut allergies eat a nuts worth of peanut protein two weeks later, a small, Stanford-led pilot study showed.
The study provides early evidence that the antibody is a safe, effective and rapid food allergy treatment. A paper describing the findings was published online Nov. 14 in JCI Insight.
Such a treatment is badly needed. About 32 million Americans suffer from food allergies, which can develop at any point in life. The only existing treatment, oral immunotherapy, requires patients to eat tiny, gradually escalating doses of their food-allergy triggers under medical supervision. Desensitizing someone to their allergens with oral immunotherapy takes six months to a year, and can cause allergic reactions along the way.
In contrast, 73% of the people who received the antibody, all of whom had severe peanut allergies, could eat a modest amount of peanut protein 15 days after a single injection of the treatment.
The studys lead author is Sharon Chinthrajah, MD, clinical associate professor of medicine and of pediatrics. Nadeau and Chinthrajah treat allergy, asthma and immunology patients through Stanford Health Care and Stanford Childrens Health.

How Do Allergy Shots Work
Allergy shots work by decreasing symptoms from particular allergens.
Each injection contains small amounts of the allergen so that your body builds up immunity to it over time. The process works much like taking a vaccine, where your body creates new antibodies to combat the invasive substances.
Allergy shots also improve the way other immune system cells and substances function in response to allergens. Eventually, successful immunotherapy helps the body fight off allergens and reduce adverse symptoms.
Allergy shots aim to decrease overall allergy symptoms over time. If you have allergic asthma, reduced asthma symptoms are also possible.
New Oral Immunotherapy Treatment For Peanut Allergy: Noah’s Story
Noah was 6 years old when he ate a piece of candy containing peanuts. His allergic reaction was swift and intense: repeated coughing, trouble breathing, puffy eyes and a swollen face. His mom gave him two doses of Benadryl and Noah recovered. But the terrifying experience left its mark on the family.
Then they discovered a cutting-edge new therapy at Children’s Hospital of Philadelphia with the potential to erase their fears.
Noah participated in the clinical trial for PalforziaTM, a new oral immunotherapy recently approved by the U.S. Food and Drug Administration to treat children and adolescents with peanut allergies. The medication, which involves a daily controlled amount of peanut protein, was designed to desensitize children and reduce the severity of allergic reactions, including anaphylaxis, due to accidental exposure to peanuts. The medication is a first-of-its-kind treatment.
This therapy is the first FDA-approved therapy for desensitizing children and teens with peanut allergies, says Jonathan Spergel, MD, PhD, Section Chief of CHOP’s Food Allergy Center. While its not a cure, it will allow patients to live their lives with less of a fear of having a serious or fatal reaction to accidently ingesting peanut protein.

Could You Benefit From Food Allergy Shots
Whether you eat a certain type of food or youre simply around a certain kind of food, if youre allergic to it, then it can be difficult living a normal life. You might have to avoid certain restaurants or avoid being in situations where people could have the foods that youre allergic to, such as business lunches or school cafeterias. Fortunately, food allergy shots are an option to consider. While they might not take away the allergy completely, they can make it a bit easier to live with the allergy and be around the food so that you dont have to worry about breaking out in hives or experiencing other reactions.
Reactions are Possible
When you try food allergy shots, you need to know that they do contain a minimal amount of the allergen. This means that its possible to have a reaction to the shot. Over time, the amount of the allergen used increases. The reason behind this is so that your body can build a natural tolerance to the food. As you continue getting the shots, your bodys immune system begins to essentially build a wall so that you dont have severe reactions when youre around those foods. For some people, they have no reactions to foods at all after being on allergy shots for the recommended amount of time. Its also possible to stop taking medications for allergies or to at least minimize the amount of medication that you take.
