Students sue over COVID-19 vaccine requirement How COVID-19 vaccines work Replay Video Students at Indiana University filed a federal lawsuit Monday, suing the school over its COVID-19 vaccination requirement.

The recently passed law prohibits state and local governments from creating or requiring vaccine passports. In the lawsuit, the students claim that they are being coerced into vaccination and that if they do not comply, they face "the threat of virtual expulsion from school."MORE: This is why vaccine lottery prizes may work for some, according to psychology experts
