Yes, this seems likely not only because the shot tampers with immune systems, but also because it reactivates a variety of dormant viruses in the recipient, such as Epstien-Barr and Herpes. So the possibilities are that either 1) natural immunity was damaged; 2) previous covid remnants were reactivated; or 3) one of the covid infections was misidentified due to faulty testing. Hopefully some of problem 3 resolves if the EUA on PCR testing is truly allowed to expire today.
