My sister's mother-in-law had her second shot last week. She was sick as a dog the next day and wasn't much better day after. I haven't checked to see today how she is. She had the Moderna one I believe. My brother-in-law did not feel well after his second shot but was not ill. I for one am not taking it. Like you though if I had to choose the J & J would be better than anything I would trust Gates to put out.
