She didn't provide any explanation.This is the Supreme Court's first legal challenge to the COVID-19 vaccine mandate.The mandate of Indiana University allows for medical and religious exemptions. Politico reported that seven students who filed the lawsuit had been granted or were eligible to receive an exemption.Barrett's decision was made after lower courts had already rejected the request. They cited a 1905 Supreme Court ruling that allowed states to require smallpox vaccinations, and noted that vaccinations are common in the US. Other vaccinations and health examinations are required for students to attend school, according to the courts.According to The Chronicle of Higher Education in the USA, over 700 colleges require at least one student or employee to be vaccinated against COVID-19.
