The COVID-19 vaccines—all three that are available—are "safe and effective," says Dr. Anthony Fauci, the chief medical advisor to the President and the director of the National Institute of Allergy and Infectious Diseases. "I would take whatever vaccine would be available to me as quickly as possible," he has said. So should you. However, a very small subset of people "should not" get the COVID-19 vaccines, says the Food and Drug Administration. Read on for the specifics about what the FDA says about each vaccine—and to ensure your health and the health of others, don't miss these Signs Your Illness is Actually Coronavirus in Disguise.
Who Should Not Get the Moderna COVID-19 Vaccine?

Says the FDA: "You should not get the Moderna COVID-19 Vaccine if you:
- had a severe allergic reaction after a previous dose of this vaccine

The Moderna COVID-19 Vaccine contains the following 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."
Who Should Not Get the Pfizer-BionTech COVID-19 Vaccine

Says the FDA: "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.
The Pfizer-BioNTech COVID-19 Vaccine includes the following 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."
Who Should Not Get the Janssen—aka Johnson & Johnson—Vaccine?

Says the FDA: "You should not get the Janssen COVID-19 Vaccine if you:
- had a severe allergic reaction to any ingredient of this vaccine.
The Janssen COVID-19 Vaccine includes the following 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."
These are the Most Common Side Effects, Says the FDA

You might feel any of the following, says the FDA, or none of them:
- injection site pain
- tiredness
- headache
- muscle pain
- chills
- joint pain
- fever
- injection site swelling
- injection site redness
- nausea
- feeling unwell
- swollen lymph nodes (lymphadenopathy)
- non-severe allergic reactions such as rash, itching, hives, or swelling of the face
- severe allergic reactions
But severe reactions have been rare. Many of these reactions indicate your body is having an appropriate reaction to the vaccine, say doctors.
So Should You Get a Vaccine?

Unless you have the allergy issues described in this article, the FDA says: Yes! As soon as possible! "When you get a COVID-19 vaccine, you are choosing to protect yourself and make a difference for your children, parents, grandparents, and other loved ones," says the agency, "Millions of people in the U.S. have already received a COVID-19 vaccine. For a community to be fully protected, most community members need to get the vaccine. Getting vaccinated against COVID-19 will help protect you from COVID-19, and it may also protect the people around you."
