> This info doesn't seem sufficient to draw meaningful conclusions about longer term protection. Is it because the study period is just that i.e. 12 weeks? Even the studies on natural immunity from COVID suggests at least 6 - 8 months antibody persistence because the study period were just that[1][2]. Note that policies are being made now to defer the jab for those who got infected by COVID, based on these studies. We'll likely see studies confirming long term protection from vaccines & natural immunity after disease in coming months. Btw, How much is long term?
