Severe allergic reactions are very rare and may develop in one to two per million people who have been vaccinated with covid vaccines
If you had a severe allergic reaction which is also known as anaphylaxis after getting the first shot of a COVID-19 vaccine, the CDC recommends that you don’t get a second shot of that vaccine.
The CDC added:
Anaphylaxis is a severe, life-threatening allergic reaction that causes a combination of hives; swelling of the face, eyes or throat; difficulty in breathing; and dizziness due to a lowered blood pressure.
The CDC has reported that between 14 December and 23 December 2020, there were 21 cases of anaphylaxis after the administration of a reported 1,893,360 first doses of the Pfizer-BioNTech COVID-19 vaccine (11.1 cases per million doses).
Of these cases, 71 percent of these occurred within 15 minutes of vaccination.
“From a medical standpoint, this would put their lives at risk,” he said.
According to Pfizer, the Pfizer BioNTech vaccine is made with synthetic and chemically produced components as well as enzymatically produced components from naturally occurring substances like proteins.
Inactive ingredients in the Pfizer BioNTech COVID-19 vaccine include:
- Potassium chloride
- Monobasic potassium
- Sodium chloride
- Dibasic sodium phosphate dehydrate
- Sucrose (sugar)
- Small amounts of other ingredients
