noticeable. I got a little extra tired and body aches after the second dose, but I think it had more to do with working out and lack of sleep than actual symptoms. Oh, and a little sore shoulder. Didn't notice a thing after the first dose. My elderly parents both got it and didn't report anything bad (my dad had recovered from Covid previously). I think a lot of people are being drama queens. 😉 Or it's likely sampling bias as previously stated - which is a lot of the hysteria regarding Covid in the first place.
