What Exactly Happened?

What could be clever, he stated, could be “for anyone who has known severe allergic reaction such that they need to carry an EpiPen to delay having a vaccination until the reason for the allergic reaction has been clarified.
“Mayo Clinic virologist Gregory Poland, who has suggested U.S regulators, described Britain’s early response as “overdoing it,” pointing to the preliminary response about meals allergic reactions, which he stated “have nothing to do with this.”
“I would have said, ‘If you’ve had anaphylactic-level reactions to vaccines, we want to know about that so we take extra care,'” he stated
“That doesn’t mean I wouldn’t immunize you. But I would do it in a more controlled setting.”
Peter Openshaw, a professor of experimental drugs at Imperial College London, praised the best way the reactions had been dealt with.
