Mel:
Not the poster you directed the question to, but thought I would contribute what I have learned.
I have anaphylaxis allergies to milk, peanut, all tree nuts, and all seafood [all fish, all shellfish].
From the research I have done, none of those appear to be contraindications to either the Pfizer or Moderna vaccines.
Here is government of Canada info about the Moderna vaccine:
https://www.canada.ca/en/health-can...ugs-vaccines-treatments/vaccines/moderna.html According to the product monograph "
Moderna COVID-19 Vaccine does not contain any preservatives, antibiotics, adjuvants, or human-or animal-derived materials."
And the Pfizer vaccine:

What consumers should do
If you know you have allergies to any of the ingredients in the Pfizer-BioNTech COVID-19 vaccine, you should not receive it.
If you have experienced a serious allergic reaction to another vaccine, drug or food, you should talk to your health professional before you receive the vaccine.
I had an anaphylaxis-like reaction to the H1N1 Pandemic vaccine, which later allergy testing determined was not actual anaphylaxis [though at the time it absolutely walked and quacked like that duck!!]. I also have a history of anaphylaxis to multiple foods and medications. Basically, my immune systems like to overreact to things it should not be. So I will wait the full 30 minutes post vaccine, not exercise the rest of the day, and carry 2 Epipens with me the the rest of the day [while resting at home], just in case. Of course, I likely won't be getting vaccinated for some months, so will be paying attention to whether the guidance changes before then.
