I got the 2nd dose at about 1:45 pm. Felt fine most of the day ... a bit tired at around 6:00 At about 8:00 that night started chills which got really bad at about 9:00pm ... I wrapped up in an extra blanket and went to sleep and was fine in the morning.

So ... 4 hours for me to the onset of any symptoms, about 6 hours to peak symptoms
