As many as 10 people have had a serious allergic reaction, called anaphylaxis, to the vaccines.
It's the runaway inflammation and swelling of tissues. As much as 5% of people in the U.S. have had such a reaction to various substances trib.al/qaLxXdt

2 people in the U.K., 6 people in the U.S. and a man in Israel who took the Pfizer/BioNTech shot had it. Also, a physician in Boston who took the Moderna vaccine suffered an allergic reaction.
None have resulted in death trib.al/qaLxXdt

Anaphylaxis has been connected to vaccines before.
A 2016 study 📖 in the Journal of Allergy and Clinical Immunology found 33 confirmed vaccine-triggered anaphylaxis cases that occurred after 25,173,965 doses, a rate of about 1.31 per million doses trib.al/qaLxXdt

The risk usually doesn't last too long. Anaphylactic reactions normally occur within minutes to hours of exposure to a specific substance trib.al/qaLxXdt
The U.K. and U.S. have advised people who have allergies to any component of a #Covid19 vaccine not to receive it. Anaphylaxis can be countered with antihistamines and adrenaline injectors that slow or halt immune reactions trib.al/qaLxXdt
🚨 These allergy treatments don’t cancel out the beneficial effects of vaccines 🚨
In the U.S., health workers are observing anyone who has received the vaccine for at least 15 minutes post-injection to watch for signs of a reaction trib.al/qaLxXdt

It's not clear what exactly in the shots is causing the allergic reactions.
The 2 leading candidates are polyethylene glycol, a chemical found in foods, cosmetics and medications, and lipid nanoparticles that encapsulate the messenger RNA, @EricTopol trib.al/qaLxXdt
