              This family photo shows Jackie Hansen at the University of Pittsburgh Medical Center on Wednesday, Jan. 26, 2022. Hansen’s immune system is so wrecked by cancer and lupus that COVID-19 vaccinations couldn’t take hold, leaving her essentially a prisoner in her home two years into the pandemic and counting. Then she finally got access to scarce doses of the first drug that promises six months of protection for people with no other way to fend off the virus. (Rolf Hansen via AP)
