I wish I had the brain power to understand all this. Am currently trying to help someone diagnosed with ME at some point - referring him to various Covid protocols, owing to his worsening with his Covid infection. This person has had 2 rounds of Astra Zeneca vaccine, then two rounds of Pfizer vaccines. He managed to avoid infection for some time, but seems the vaccines finally lost their mojo after 12 weeks from the last dose and nothing has helped so far. His IgG for SARS Co V2 is through the roof, D dimer indicates the body is trying to deal with something, but what can this person do? This person is also trying to recover from surgery for tethered cord.
