Hi debbie75. My circumstances similar w very different illness dec 2021, no access to covid test possible. Pcp urged second vaccine jan 2022. More increased reaction to it and then exposed to verified covid first of Feb, testing positive w available covid test that time🙃. It has been explained to me that my body probably was not tolerating the vaccine well due to my past ebv etc, and then immediate exposure to covid created my bodies overreaction causing long haul. Know everyone has different circumstances with health and reactions they experience and medical advice needed for each individual. Hope this helped shed some light of your question (hopefully my brain understood it lol) from the post covid clinics perspective I attended. Healing to you🌈
