As a long-time asthmatic and a recent breast cancer survivor, I’m already at high risk of developing serious complications if I get an upper respiratory infection like COVID-19. Things can turn bad quickly if I even get so much as a cold. The last time I had the flu in late 2003 — the one year I didn’t get a flu shot — I actually feared I might die alone in my house. That’s how much I suffered.

But I’m at even greater risk today...
