I got the Moderna a month ago with no side effects at all. Got the second Moderna last Wed. Felt good all day.
Thurs had a head ache all day, some chills, and was very tired. Friday I was fine and same today.

Girlfriend had the Pfizer shot. She was tired for two days after the first one. No reaction to the second one.

Seems that everyone's reaction is different but its better than getting Covid.
