The league pointed Rodgers to the NFL-NFLPA protocols, which do not account for such an exemption for players. So, Rodgers remained subject to a variety of restrictions, including daily testing, mask-wearing and high-risk close contact protocol that would force him to isolate for five days based on interaction with a positive individual, even if he tested negative. If his antibody levels are high enough, Rodgers could be considered fully vaccinated with just one shot. The NFL-NFLPA regular-season COVID protocols allow for an individual to become fully vaccinated via "a quantitative antibody test (taken at the Club facility and administered by BioReference Laboratory personnel after Aug. 26, 2021 and before the individual has received any dose of a COVID vaccine) demonstrating COVID total antibody levels (IgG, IgA, IgM) to the spike protein of 100 U/mL or greater, and a positive antibody test to the COVID IgG nucleocapsid protein, and 14 days have passed since the individual received one dose of any COVID vaccine (Johnson & Johnson, Pfizer or Moderna)." Sources, however, told NFL Media that Rodgers has not received one of the COVID-19 vaccines. So he HAS apparently gone the "snake oil" route.
