Very inconsistent': 2 allergic reactions in the UK to COVID-19 vaccine puzzle researchers
Two British people with severe allergies apparently had allergic reactions to Pfizer/BioNTech's COVID-19 vaccine, raising questions about whether it is safe for people with preexisting allergies.
In response, British regulators advised those with severe allergies to avoid the vaccine.
It was not immediately clear what triggered the allergic reactions. Unlike some vaccines, in the Pfizer/BioNTech vaccine there are no preservatives or egg products, which have been known to trigger reactions with other types of vaccines.
Allergic reactions were not a significant problem in the U.S. trial in which more than 20,000 people have received both two doses of the vaccine, but the U.S. trials kept out subjects who have had severe allergic reactions, said Moncef Slaoui, co-head of Operation Warp Speed – the government program tasked with developing, manufacturing and distributing COVID-19 vaccines.
Slaoui said he assumes that the U.S. Food and Drug Administration committee meeting Thursday will discuss this issue and will suggest that people with severe allergies "should not take the vaccine until we know exactly what happened."
But a vaccine that triggers dangerous reactions in people with severe allergies poses a major challenge in the U.S., said Dr. Peter Hotez, a pediatrician and dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston.
If you start issuing recommendations that anyone with an EpiPen doesn't get vaccinated, that could be a showstopper for Americans," he said. About 3 to 4 million Americans carry epinephrine with them at all times in case of allergic reactions, Hotez noted, and 50 million have less severe allergies.

I read they did not allow volunteers with sever allergies to join the research so here we go with a very inconsistent serious reaction.
