Hi @merpreb , you mention "...compared to the Covid vaccine.....". I am just wondering your experience with the Covid vaccine? Each time my reaction seems worse (not allergic symptoms), but 4-6 days of fever, chills, horrible muscle aches & weakness, bone pain, bad headache - do you get this horrible reaction? Makes me not want to get my shingles shots or another Covid shot ever & wondering why I react so strongly - is something whacko in my immune system! Just wondering if your experience is similar & your thoughts. (I have idiopathic bronchiectasis & MAC infection, so I want to keep lungs healthy as possible but UGH with my apparent vaccine sensitivity!)
