Because of my profession I was near the head of the line and got Pfizer #1 in late January & #2 in mid-February. I nearly cried with relief when I got #1 -- it was surprisingly emotional. 

#1: minimally tender injection site; I've had many flu, tetanus, and other immunizations that were far worse. 
#2: side effects begun at 6 hours and significantly subsided by 36 hours.  Somewhat sore arm, temp 100.9, chills, sl. nausea, lassitude, muscle aches, headache, no appetite.  Refused chocolate.  At 30 hours it was almost like flipping a light switch (many others are reporting this too): I felt better by the hour and great by 36 hours.   

Because of my profession plus volunteer work at immunization sites I've heard side-effect stories by the thousands since December.  There seems to be no predicting how "noisy" an individual's immune system is (and post-vaccine side-effects are unrelated to efficacy).  A number of people don't even have a sore arm. Others have a few mild side-effects. Others, like me, are more symptomatic for 1-4 days.  I haven't personally known of a single person who had a "serious" reaction...which includes the day I worked in post-vaccine monitoring.  Our team gave nearly 600 Pfizer second doses that day.  Each person was queried prior to #2 administration and not a single person reported having serious issues after #1.  In fact, one man was asked prior to his 2nd dose how he felt after #1.  His reply: "Happy!!"

Totally agree with you, Star: this is global and must be managed that way.  No man is an island, particularly for this.
So interesting and excited you are in a study, Spence!
Congrats to everyone who is getting or has gotten immunized!

Good luck Griffin-ji.  I hope your niece gets her head on straight about this and gets it done.  I felt liberated when I got my second shot.  It felt like Mike Tyson had hit my shoulder and I was a bit grumpy for a bit, but other than that, I was fine.
 

Can't understand the antivaxers. But I'm in the last generation that saw the effects of polio in our classmates. I had one whose mother fainted when she saw the iron lung waiting outside her child's hospital door ... that's how close she was to being in one. (fortunately she pulled through). And the so called childhood diseases are no joke -I caught measles in grad school, one of the last waves of that before the vaccines were widely distributed. It was a most unpleasant experiance. I had aftereffects for over a year.
 

My daughter (30 yo) is getting her first shot today.

And I got my first Shringix shot, so yay no shingles for me ! 

Still waiting for the opportunity to be vaccinated over here in the Outer Colonies.

The rollout has been a complete balls-up by our federal government - treated as a cynical political exercise from day 1 and now that it is actually needed on the ground it is simply missing in action - no secured supplies, no proper supply chain processes, no clarity of targeting priorities and no transparency around responsibilities. 

And now with the clotting risks showing up in the Astazeneca and J&J vaccines, there is even more blame-shifting and arse-covering going on.

So it goes.
