It's a privacy issue. Teams are not supposed to reveal which players are vaccinated and which players are not, however, vaccinated and unvaccinated players are treated differently in accordance with the NFL covid protocol. Likewise, once they test positive. So you have to read between the lines and make note of how players are being treated. Then you can figure it out for yourself. The Packers have announced Rodgers is out until the day before they play Seattle at a minimum, due to testing positive. So you do the math, why would that be unless he was unvaccinated?
