An immediate allergic reaction means a reaction within 4 hours of getting vaccinated, including symptoms such as hives, swelling, or wheezing (respiratory distress).
“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
Some people have no side effects. Many people have reported side effects that are generally mild to moderate and should go away within a few days.
Symptoms of anaphylaxis often occur within 15-30 minutes of vaccination, though it can sometimes take several hours for symptoms to appear.
Monitoring of the Moderna COVID-19 vaccine has found 10 cases of anaphylaxis after the administration of 4,041,396 first doses of the Moderna COVID-19 vaccine. In 9 out of these 10 cases of anaphylaxis, the recipient of the vaccine had onset of symptoms within 30 min of administration.Oct 28, 2021
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

The known risks of COVID-19 illness and its related, possibly severe complications, such as long-term health problems, hospitalization and even death, far outweigh the potential risks of having a rare adverse reaction to vaccination like myocarditis or blood clots.Mar 16, 2022
