The Moderna and Pfizer-BioNTech COVID-19 vaccines are the first two COVID-19 vaccines authorized by the Food and Drug Administration for emergency use and already have been given to millions of Americans.

“Overall, severe allergic reactions to COVID-19 mRNA vaccines, including life-threatening anaphylaxis reactions such as low blood pressure and difficulty breathing, are rare, on the order of five cases per million vaccine doses administered,” noted Dr. Guerrerio.Mar 9, 2022
An immediate allergic reaction happens within 4 hours after getting vaccinated and could include symptoms such as hives, swelling, and wheezing (respiratory distress).
There is a remote chance that the Moderna COVID-19 Vaccine could cause a severe allergicreaction. A severe allergic reaction would usually occur within a few minutes to one hour aftergetting a dose of the Moderna COVID-19 Vaccine. For this reason, your vaccination providermay ask you to stay at the place where you received your vaccine for monitoring aftervaccination. Signs of a severe allergic reaction can include:• Difficulty breathing• Swelling of your face and throat• A fast heartbeat• A bad rash all over your body• Dizziness and weakness
The most commonly reported side effects were pain at the injection site, tiredness, headache, muscle pain, chills, joint pain, nausea and vomiting, swollen lymph nodes in the same arm of the injection and fever. Side effects typically started within two days of vaccination and resolved two or three days later.Feb 16, 2022
Symptoms of anaphylaxis often occur within 15-30 minutes of vaccination, though it can sometimes take several hours for symptoms to appear.
If you are allergic to an ingredient in a COVID-19 vaccineIf you have had a severe allergic reaction or an immediate allergic reaction—even if it was not severe—to any ingredient in an mRNA COVID-19 vaccine, you should not get either of the currently available mRNA COVID-19 vaccines (Pfizer-BioNTech and Moderna).
• If you had a severe or immediate allergic reaction after getting the first dose of an mRNA COVID-19 vaccine, you should not get a second dose of either of the mRNA COVID-19 vaccines (Moderna or Pfizer-BioNTech).
If you have had a severe allergic reaction to any ingredient in the Pfizer-BioNTech COVID-19 vaccine (such as polyethylene glycol), you should not get this vaccine. If you had a severe allergic reaction after getting a dose of the Pfizer-BioNTech COVID-19 vaccine, you should not get another dose of an mRNA vaccine.
Dr. Choi says it’s actually quite common for people to get rashes when they’re battling this type of infection, especially viral respiratory ones.“It’s not uncommon for someone to have a viral infection and have a rash or blotchy areas on their body. This can happen with other viral respiratory infections like measles. And sometimes, antibiotics might cause skin rashes,” says Dr. Choi. But at this time, there is no specific rash pattern that’s associated with COVID-19.Nov 24, 2021
