My first booster was hellish. A few days after getting it I was gifted with muscle pain in my back where I never knew muscles existed. Away from the spine, and up and down. Lasted almost two months. Not only eliminated my daily bike rides but made me pretty immobile.
As I slowly recovered, I believe it resulted in my pulmonary embolism ( many small blood clots in my lungs), and (hopefully temporary) heart issues. Oh and yay blood thinners. Now have a retina detachment surgery Thursday’s and can’t stop the blood thinners… so bleeding will be an issue.
I am a believer in vaccines too. But one of your responders says EVERYONE should get the second booster.
Not me.
