First Covid-19 shot

I got my first shot of Moderna on December 28 and the second round January 30.

I'm still alive and I never had any side effects except a sore arm where the needle poked. I have never had covid and hopefully never will.
I'm 34 and worked around a ton of covid positive people all of 2020. Not sure how I never got it but I have been tested over and over and negatory every time. I was never one to get sick often even before this mess.
