High school administrators in New Hampshire decided to take Nathaniel Hawthorne’s The Scarlet Letter a little too seriously, separating its vaccinated students from the unvaccinated with a red mark.

Unvaccinated students were marked with a black Sharpie on their hands, while those who did show their vaccine cards were given a red mark.
