If you're not prone to hyperventilating I would seriously consider getting the jabs. I had the Astro and zip, nada, zilch, nought adverse symptoms, although the first shot is supposed the one that will give you reaction and the second jab benign. The Pfizer is the one that seems to go well with a Bex and laydown after the second shot.
Your call of course, but fear shouldn't be the primary factor over survival and being around for your friends and family. IMO
