I just tried on my father in-law who recently took the Pfizer vax with a couple different magnets and none stuck. We tried a lot of different spots in case he misremembered where the shot was and nothing stuck.

Not saying it's not true, but definitely not everyone and this is a firsthand account of it not working.

My brother in-law got the J&J so I'll try on him sometime if I get the chance.

Update: I tried with my brother in-law and it didn't work either. Not sure if there were any claims of this with J&J but here's anecdotal evidence to the contrary anyways.
