Laws are generally not stupid enough to allow magic wording loopholes.

If it’s obvious that the nurse saying they gave the boy a “brave boy” sticker means the boy got a vaccine, that’s the same thing as saying he got a vaccine.

Compare to hypothetical statements like

“I can’t say what procedure she got, but she’s going to need to keep buying tampons for the next 9 months”

“I can’t say what procedure they got, but they’ll definitely need to sit to pee from now on.”

“I can’t say what procedure he got, but keep strong magnets away from his chest.”
