Minors didn't get a choice. They screamed while getting their vaccine because Mom or Dad said they would. Smallpox vaccines stopped being given in in 1972. (I have no idea your age).
I'll assume you've had a 19yo patient crying her eyes out, that you talked to for 20 minutes b4 she let you give her the injection while pulling away the entire time? I won't tell all the stories of patients I've talked off the ledge in the recent 4 weeks let alone 4 decades.
It's a good thing my professional integrity doesn't rely on your evaluation of my expertise.
Have a lovely day.
