The current data for how immune from Covid you are, by getting infected with Covid. For the current JN.1 variant. Effectiveness is against being reinfected. So for 3-6 months, about 80% effective at blocking another infection (margin of error 40-90). By a year, about zero. If you’ve not had Covid recently and no recent vaccines, you’ve had zero protection for a long time. The idea that by keeping catching Covid your immunity builds up gradually is bunkum.
