For what it is worth I got my second Moderna shot last Friday. The first gave me no side effects while the second gave me flu-like symptoms for about nine hours. Had the shot at 11:30am and felt body aches and chills starting at 11pm. That night was like a rough, albeit very short flu. Was lethargic until about mid-day.
I got the second Pfizer vaccine shot on the 12th and what you describe is similar to what I felt on the 13th.
