Anaphylaxis - severe, potentially life-threatening allergic reaction - can occur within seconds or minutes of exposure to allergens. Multiple cases of anaphylaxis have been described for COVID-19 vaccines.
For the Pfizer/BioNTech vaccine, twenty-one anaphylaxis cases (a rate of 11.1 per million doses administered, later updated as 4.7/million from 28-million-datapoints), were documented in the US after receipt of the first dose of Pfizer-BioNTech COVID-19 vaccine during December 14–23, 2020. 17 of those had a documented history of allergies or allergic reactions, seven of whom had a history of anaphylaxis. 71% of them occurred within 15 min following the first dose of BioNTech vaccine.
The Pfizer-BioNTech vaccine contains lipid nanoparticles one of which is “pegylated” (Polyethylene glycol, molecular weight 2000 Da, abbreviated to PEG2000). The Moderna mRNA vaccine also includes a different pegylated lipid (also a PEG2000). Polyethylene glycols, also known as macrogols, could be causing serious allergic reactions ins some people.
One of the culprits of anaphylaxis in Astrazeneca could be polysorbate 80, used in the formulation of protein-based biopharmaceuticals, cosmetics, skin-care products, chewing gum and foods (ice creams and puddings). 41 reports of possible anaphylaxis were seen among around 5 million vaccinations in the United Kingdom. Four cases of people potentially experiencing anaphylactic reactions within 30 minutes of receiving the AstraZeneca vaccine have been reported in Queensland and one case with fatal outcome happened in Georgia.
Polysorbate 80 is also an ingredient in Johnson and Johnson vaccine. For this vaccine, no cases of anaphylaxis were reported in ~22,000 participants of phase 3 clinical trial who received it. Five patients reported developing hives within a week. There was one case of what was considered severe “a hypersensitivity reaction,” but it was reportedly not related to anaphylaxis. Last month, however, one individual in South Africa developed anaphylaxis. No details have been published yet.
According to the CDC, polysorbate 80 is an inactive ingredient in many viral vector vaccines for influenza (Fluarid, Fluax, etc), rotavirus, shingles, Hepatitis A, Hepatitis B, HPV, and meningococcus. Polysorbate 80 is also an ingredient in COVID-19 Sputnik V vaccine from Gamaleya Research Institute.

I wouldn ‘ t so much call it ” allergies ” as I would call it ” polluted air ” . I ‘ m sure big cities are worse , the ones I ‘ ve been in are anyways , but Kihei is not the place to come for fresh air . If you had to be on Maui , I’ d suggest something Hana way , I ‘d LOVE to be there myself , but we ( gf and myself ) are not bohemian millionaires , nor are we locals , so nix that idea . If you have the money it ‘s the place to be …..
unless if you have problems with mold . In which case , Kaua ‘ i , and Hilo area would be bad for you …. they both have a very wet climate , as I ‘ m sure you know Hana area has as well ( although not nearly as wet ) .
My ” best ” suggestion for you two , I ‘ d guess something on Oahu , away from the city for sure , maybe towards North Shore , although somewhere thats not tooo wet . Oahu doesnt seem to get the vog as badly ( although they did get a spell of it around the time of the World Series last year ) as islands that are closer to Big Island …..
by the way , your husband prob got sick between May and August because of the wind pattern at that time of the year …. pulling vog from Big Island .
Lastly , I am a runner , moved from Minnesota , and the amount of stamina I ‘ ve lost in the year and a half that I ‘ ve been here ………wow .( And I run at night mostly. ) They burned here on Friday and now several people at work ( today is Sunday ) are sick …… I guess my points are 1.) money always tries to blame people for their ” allergies ” as they are sickening people ; 2.) there are better places out here than Kihei.

I’m on Maui now. Different grasses but the Waddle trees here leave enough pollen to coat a house! Shorter season than grass though, and not quite as bad. Cost of living here is killing me instead!
