Following President Biden’s announcement mandating vaccinations for companies with over one hundred employees, major professional sports leagues may be required to ensure compliance with the mandate. This mandate has the potential to have sweeping implications throughout professional sports, from the athletes, to staff and even spectators. The NFL, NBA, and MLB all have high vaccination rates among their players and the staff that works closely with them, since many teams have already mandated that players and those working in “close proximity” to them be vaccinated. However, their back-office staff are less protected, as those employees have yet to be subjected to strict protocols of the rest of the leagues. Despite these high vaccination rates among athletes and certain staff members, the leagues have been reluctant to institute absolute mandates. But that doesn’t mean that athletes don’t still have a responsibility not only to get vaccinated but also encourage others to do so as well.
