Yes, it’s extremely normal. The exigence not to exercise following the c19 vaccine cannot be understated.
Getting both usually knocks me out for 24-48 hours—my immune system tends to be a bit dramatic. I take two days off with an easy day on the third, which is still better than taking a week or more off with COVID or the flu, plus a slow ramp back into things.
There are studies showing that vaccines are much more efficient when people are resting vs non resting. In One study for example, from memory, vaccines were loosing 40% of their efficiency with people prevented from sleeping for 24hours.
That’s a bit different to saying exercise was affecting it. Most people sleep just fine on days they exercise.
Short answer - yes. It is normal.
I had several covid vaccin with no effect.
Last September i went for a covid shot on sunday, next monday i was dead, and tuesday firing all cylinders .
All good mate
That’s quite a recovery! I’ve never successfully recovered from being dead.
