I had my 2nd shot of Covid-19 vaccine yesterday (Moderna). I didn't turn green or sprout gills. I heard there can be a severe immune response, but I didn't get that fortunately unless it kicks in today.
I wanted the Moderna (I'm a shareholder), but they didn't have it so I went with Pfizer; 1 shot so far, a bit tired for 2 days... then I got kidney stones Again! But I don't think this is related to the vaccine, Very likely just a coincidence.
I've got my second Moderna shot scheduled for May 7. The first one, I had the typical sore arm with a mild, dull headache the first night, and I just felt a bit tired.
I got the shakes with mine, like 12 hours later. I thought it was hypothermia since it was raining cats and dogs and it soaked through my jacket. But I guess a lot of other folks got it from the vaccine.
