Wouldn’t it be better to track recent antibody scores, rather than whether you got a shot. It was recently published thAt 30% of immunocompromised folks did not develop any antibodies after the first round. False security.

Plus, we now know immunity wanes over time. I heard that your immunity can go up/down daily based on other factors like other sickness, even sleep.
