COVID is still out there, getting sick after not being sick for 2-3 years is worse than before, and the immune compromised people didn't just disappeared. Same time, having my sick days for actually things I need rather than getting sick twice a year on schedule from working in a lab where sick people touched everything. It's been a complete godsend.
