and it didn’t go quite as expected. I’m well versed on side effects and such, but just wasn’t expecting anything substantive. Within 2.5 hrs I had a hell of a headache and chills. My neck got stiff and sore and I was sent home from work. The arm soreness is a little crazy too. But I attribute this to the nurse administering the dose. Sides have chilled out today, just a little fatigued. Anyone else have similar side effects , or none at all? My wife received the Moderna the day before I got mine, and she didn’t experience anything whatsoever besides a sore arm.
