Question about Covid Vaccine in regards to pain meds

My dad had a shot of Astra Zeneca a little over a week ago. He hasn't experienced any side effects but he finds now his pain medication has no effect. It may not be related to the vaccine but normally he's very sensitive to it a pill would be more than enough he tried one it had no effect and the next day he took 2 pills which would probably have him on another planet and there was again zero effect nothing positive or negative it was like he took nothing. Has anyone heard of this being a side effect to the vaccine?

Oh!

Normally vaccines are researched for years before doled out. We're the dummy run for the future. They'll be finding side effects for years.

Hope dad is ok

@SW-User Yes because how many people during vaccine testing were on pain medication at the time? Was that something that had to disclose, maybe that would even preclude them from participating in the research? I mean it may have nothing to do with the vaccine it's just weird I think the last time he took them was about a week before the vaccine and they worked fine and he popped a couple last night and still had no effect he normally one takes one he's never taken 2 before so for 2 to have zero effect is very strange.
