I got my first Moderna dose on late afternoon on Sunday... Jan 24. Pharmacist said that the second dose is Feb 20. She said that the CDC counts the day of the shot as day 1... so the 28th day is Feb 20. I would have thought that the day of the shot is day 0. So 28 days for the second dose would be Feb 21. Any comments?

Also, the first day after the shot... only had pain in the upper arm where the shot was given. Second day... only mild soreness in the arm... just enough to remind me that something happened. No other effects. Based on what has been said, I’m kinda anxious about the second shot.
