Imagine that you are the parent of an 11-year-old soccer player who dreams of competing in the Women’s World Cup one day. You want to support her love for the sport while keeping her safe from harm.

What protects better from future COVID-19 infection, previous infection or vaccination? (Cory Franklin, 10/24)

In March 2020 I contracted a mild COVID infection. I had just turned 30, was in perfect health and living “my best life.” The Centers for Disease Control and Prevention told me it would take two weeks to bounce back. But it’s been 2½ years, and I’ve spent my entire 30s disabled by a post-infection illness — housebound and barely holding onto what little I can of my former life. I truly cannot relay the misery.

Chomilo and Neil A. Lewis, Jr., 10/25)

While many Americans are familiar with the devastating impact of Alzheimer’s disease, few understand the cruel disparity with which it strikes. Black Americans are twice as likely to be diagnosed with this mind-robbing disease and bear the greatest costs of caring for loved ones suffering with it. (Linda Goler Blount, 10/24)

Now I’m almost 77 years old, and since losing my mother and older brother to Alzheimer’s disease, I have been on the lookout for small clues that might make me the next victim. (Mike Lindsay, 10/21)
