I had my second Morderna shot on May 14th. No side effects except soreness in arm a couple days.
I had both Moderna shots, both times all I had was a sore arm for a couple of days. Not everyone has the same reactions though.
I've had my 2nd shot of Moderna sore arm and tired that was it same as first but everyone is different
Had the second one too . A little tired and slight fever the 2nd day ,but all was well the 3rd
Just got the first shot yesterday--I was tired and sore arm and a little light headed--wish I could answer for you second shot not till May
