Proof of immunity is fast becoming the next major debate in the pandemic, with vaccine mandates or limits to freedoms are being considered as a means to encourage vaccination to boost immunity in the population. Recent research on SARS-CoV-2 viral immunity seems to show that vaccines help produce shorter lasting circulating antibodies and memory B cells, generating effective immunity for a shorted period than the slower evolving memory B cells that the human body produces from fighting an actual SARS-CoV-2 infection. As more and more regions look toward mandating vaccines to try and stem the pandemic, should the superior immunity gained from infection begin to be factored into calculating who is forced to take the vaccines, or who is denied certain freedoms or services based on their vaccination status?
