I had two AZ shots, the first made me spend 12 hours in bed, the second I barely noticed, and as far as I know, in both cases I did the same thing afterwards (waiting for 15 minutes reading a book, then walking home for 30 minutes). So, who knows, maybe the effects of the second vaccines are just weaker in general.

On average second shots have higher side-effects because there’s a larger immune response.
