It will be interesting to understand the long-term impact of covid on immunity. Given that covid came from GoF research have we developed defenses (albeit at an ultimately very-high price) that will protect us from future novel coronaviruses ?

other classes of virus? (ie how the plague resistance in those of european descent gives some level of protection against hiv [0])

Is this something we have a way to measure or will it be impossible to tell once everyone in the world has some amount of covid immunity?
