We got infected for first time ever last September, were double boosted (so 4 doses in total) prior to that and the new boosters (for the BA strain family) were just coming out at that time which we were planning to take. It hit us bad, Paxlovid helped a lot getting it out. Then we got infected again in December as JA.1 started spreading everywhere but just a mild cold this time. The new strains are just so infectious and by the time the vaccines targeting them are available, most people are already infected.
