Anaphyaxis is not an allergic reaction. Swallow gasoline and you’ll likely go into anaphylactic shock - your body needs to have had no other experience with whatever substance you’re dealing with in order to have this reaction.

Yes, I wondered that if people who have had COVID, but did no know it at the time, would have a reaction to the vaccine.................

It might be a reaction to PEG or some other component of the vaccine that was used in an earlier vaccine. Not all of the antibodies provoked by vaccine components are neutralizing for the disease antigen. The adjuvants added may trigger antibody production and have a much bigger reaction when encountered at a point in the future.
