The only studies I’ve seen from the CDC showed levels of anti-bodies up to a year after infection but the level of anti-bodies and t-cells varied and generally decreased the less severe the infection was. So people hospitalized with Covid had more and longer lasting anti-bodies than those who had mild covid. There is no good way of knowing if that has any impact on future infections. The people with severe covid infection had anti-body and T cell levels approaching the level of vaccinated people. That study was a while back but I’m sure there are more being done. If you are asking if there is definitive proof that natural infection is equal to vaccination I haven’t seen anyone saying that.So we are now 18 months into this event and the CDC has done no research into the longevity of natural immunity?
As to.skill certificate, both certificate of vaccinated and.natural immunity come from governmental health entities, if not the same county Department of Health
