Green Bay Packers quarterback Aaron Rodgers has revealed that he has an allergy to ingredients in two of the FDA-approved COVID-19 shots so he sought alternative treatments instead of the NFL-endorsed vaccinations.

Rodgers was speaking on SiriusXM’s “Pat McAfee Show” on Friday. The quarterback said: “I’m not an anti-vax, flat-earther. I have an allergy to an ingredient that’s in the mRNA vaccines. I found a long-term immunization protocol to protect myself and I’m very proud of the research that went into that.”

Rodgers has been tested daily as part of NFL protocols for the unvaccinated player. His Wednesday test came up positive for the coronavirus. Rodgers said that though he didn’t feel well on Thursday, he was much better on Friday.

He has to wait for at least 10 days to rejoin the Packers. That means he will be missing Sunday’s game against the Kansas City Chiefs. Rodgers must have a negative test to return to the team on November 13.

Rodgers told McAfee he has concerns about potential fertility issues had he taken one of the vaccinations.

In July, three doctors who specialize in reproductive health vouched for the safety of vaccinations for couples who want to have a baby and urged people to seek out their doctors or nurse practitioners with any questions.

Dr. Stephanie Broadwell of Sanford Health Fargo, Dr. Stephanie Foughty of Altru Health Devils Lake, and Dr. Ana Tobiaz of Sanford Health Bismarck basically said to get the vaccine.

“I can understand that people are scared, people are nervous. I think sometimes there can be information that can be helpful and some that can be somewhat misleading. I think it’s just really hard to digest all the information that is out there and stories that are filtering through that maybe even come from trusted sources,” Broadwell said, according to the Associated Press.
