August 1, 2021

Do the Pfizer, Moderna or Johnson & Johnson COVID-19 vaccines contain gluten?

No, none of the currently available COVID-19 vaccines in the United States contain gluten.

Pfizer-BioNTech COVID-19 Vaccine ingredients: mRNA, lipids ((4-hydroxybutyl)azanediyl)bis(hexane-6,1-diyl)bis(2-hexyldecanoate), 2 [(polyethylene glycol)-2000]-N,N-ditetradecylacetamide, 1,2-Distearoyl-sn-glycero-3- phosphocholine, and cholesterol), potassium chloride, monobasic potassium phosphate, sodium chloride, dibasic sodium phosphate dihydrate, and sucrose.

Moderna COVID-19 Vaccine ingredients: messenger ribonucleic acid (mRNA), lipids (SM-102, polyethylene glycol [PEG] 2000 dimyristoyl glycerol [DMG], cholesterol, and 1,2-distearoyl-sn-glycero-3-phosphocholine [DSPC]), tromethamine, tromethamine hydrochloride, acetic acid, sodium acetate, and sucrose.

Janssen COVID-19 Vaccine ingredients: recombinant, replication-incompetent adenovirus type 26 expressing the SARS-CoV-2 spike protein, citric acid monohydrate, trisodium citrate dihydrate, ethanol, 2-hydroxypropyl-β-cyclodextrin (HBCD), polysorbate-80, sodium chloride.

Latest Updates

August 23, 2021

Pfizer-BioNTech coronavirus vaccine was granted full FDA approval and is now the first fully FDA-approved COVID-19 vaccine.

March 12, 2021

There are now three COVID-19 vaccines currently available under Emergency Use Authorization in the United States, developed by Pfizer, Moderna and Johnson & Johnson. Clinical trials of all three of these vaccines show they are highly effective.

The Beyond Celiac statement on COVID-19 vaccines and celiac disease:

Beyond Celiac encourages all members of the celiac disease community to receive a COVID-19 vaccine as soon as they are able. Both currently approved vaccines require two doses to be effective. You should make the decision to receive the vaccine in consultation with your doctor, who knows your personal health history. The Beyond Celiac recommendation is based on CDC guidelines along with publicly available evidence and the expert opinion of our science team.

From the Society for the Study of Celiac Disease (SSCD):

As scientists and clinicians who care for people with celiac disease, we urge people with celiac disease to receive a Covid-19 vaccine that has met government regulatory approval. This includes agents comprised of RNA (a vaccine technology that has been in development and has undergone safety testing for years) and peptide (protein) vaccines.

From the FDA:

On December 11, 2020, the U.S. Food and Drug Administration issued the first emergency use authorization (EUA) for a vaccine for the prevention of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 16 years of age and older. The emergency use authorization allows the Pfizer-BioNTech COVID-19 Vaccine to be distributed in the U.S.

You should not get the Pfizer-BioNTech COVID-19 Vaccine if you:

  • had a severe allergic reaction after a previous dose of this vaccine
  • had a severe allergic reaction to any ingredient of this vaccine

Celiac Disease & Covid-19 Vaccines

by the Beyond Celiac team

On December 8, 2020, 90-year-old Briton Margaret Keenan became the first person to receive a shot of Pfizer/BioNTech’s COVID-19 vaccine as a part of the UK’s mass vaccination program for the novel coronavirus. This marked a giant leap forward in the fight against this global pandemic.

The U.S. Food and Drug Administration is expected to follow suit with approval of this vaccine in the coming days or weeks. Yet as the world begins to roll out these vaccines for COVID-19, we’ve received a number of inquiries from our community about their safety along with the safety of vaccines in general for those with celiac disease.

To help answer some of the most common questions we’re receiving, we asked Salvo Alesci, MD, Beyond Celiac chief scientist and strategy officer for his thoughts. Below are his responses.

Are the COVID-19 vaccines safe for those with celiac disease?

There is no scientific evidence for the time being to indicate that the Pfizer or Moderna vaccines (or any other being developed for COVID-19) could be less safe and/or effective in the celiac population vs. the general population.

Note: UK regulators advised people with severe allergies/previous anaphylactic reactions to not get the new Pfizer vaccine ( As a reminder, celiac disease is an autoimmune disease and not an allergy.

Are messenger RNA (mRNA) vaccines safe for those with celiac disease?

Information released so far indicates that these vaccines appear to be safe and effective, but there has been no specific mention of the celiac disease population. We put trust the regulatory process.

Since both vaccines are under emergency use authorization and still going through the formal approval process, we shall wait for the FDA to determine the overall safety and efficacy on such vaccines. And even after regulatory approval, as with any drug, it will not be until the vaccine reaches millions of people that we will have more robust data to have a better picture on safety and efficacy in the general population as well as in subpopulations like patients with celiac disease.

Regulators mandate companies to have safety surveillance and life cycle management programs after approval is granted to continue assessing safety and efficacy of the treatments.

Are vaccines in general safe for those with celiac disease? 

All currently available vaccines worldwide that are parenterally administered can be safely taken by celiac patients, as stated by the University of Chicago Celiac Disease Center (

There is also no evidence that vaccine administration can cause celiac disease, as concluded by a couple of studies, including a pretty large Swedish study (

A few studies, including work done by Joseph Murray, MD, have shown that a particular type of vaccine, the one for hepatitis B may be less effective in celiac disease patients. The reason is not clear. Genetics may be a factor. However, it was shown that adherence to the gluten-free diet may be another factor. In fact, researchers found that if children are on a gluten-free diet, then the response to this vaccine is similar to people who don’t have celiac. Also, children who originally did not respond well to the vaccine, develop a better response after a gluten-free diet. If anything, the lesson here is that if a child doesn’t respond to HBV vaccination, they should be tested for celiac disease (

There has been a report of a higher rate of celiac disease in women who received a vaccine for HPV, which aims at preventing cervical cancer. However, the authors noted that women who received the shots and subsequently were diagnosed might have had their celiac disease “unmasked” because they talked to their doctors about their celiac symptoms when they received their HPV shots (
