You know who else tattooed human medical test subjects?

Have you always wanted a tattoo, but can’t decide between the tribal armband or kanji word for “tribe?”  And have you always wanted to get vaccinated, but are worried that the needle will scrape on your bone?

Remember, these will be administered by hospital staff, so you might not want to request any designs that involve handwriting.
