Work colleague had his second jab last week,said to load up on panadol for the second jab,really felt the effects for 24 hours after the second jab(Pfizer I think).Recomends not planning much for the day after......
My wife is a health care professional and her view is to try avoid anything like that as it is good for body to work through it (unless of course you are not able to / your own circumstances are different)
