We re zeroing in on the holy grail of vaccine immunity

Katherine Wu Jul 24, 2021 9:45 PM ET She was able to confirm that in June through a simple test that searched her blood for antibodies that recognize the rubella virus, and then added them up. If her antibody counts were above a certain level, called a correlate of protection, she and her babies would be considered well shielded from disease. “You are considered immune with a titer of 9.9 to rubella,” she tweeted last month, referring to her antibody levels. “My titer? 116. I love my immune system sometimes.” The term correlate of protection doesn’t exactly roll off the tongue, but it’s one of the sexiest concepts in the field of vaccinology. Correlates are biological benchmarks measurements of a single immune molecule or cell that can show that a vaccine is achieving its desired effect. With a correlate in hand, researchers can confirm how well a shot is working and identify the rare individuals in whom it doesn’t take; they can suss out the need for boosters and fa

The American pandemic day: More kids More TV More ZZZs More time alone

WASHINGTON Americans watched more TV last year, played more computer games, thought and read a bit more, caught up on a little sleep and on average spent an extra hour each day alone and two additional hours wrangling or educating their kids. Exercise? Meh. The pandemic upended daily life for much of 2020, and updated government data released Thursday pinned down by just how much. The American Time Use Survey, a detailed accounting from the Labor Department of what people do each day, confirmed much of what is already known or suspected about the months under lockdown and quarantine, from the increased burdens of childcare, particularly for women, to the jump in home-based work.

OPINION: Road to college

Steven Glovsky If it hadn’t been for Robert Frost, I’d have gone to Dartmouth. Growing up in the Kennedy years, Frost was my favorite poet. (JFK invited him to recite at his inauguration.) It was just assumed that I’d be my family’s 10th in a row to go to Dartmouth. And in my house, no one suggested visiting other campuses. Then I chose “the road not taken” and went to Harvard. Our son’s college tour in the summer after his junior year in high school turned into one of our best family vacations. As a child, “college” meant the Ivy League plus Smith (my mother and her two sisters went to Smith). So as a parent, I was amazed to discover the almost endless choices The Princeton Review outlines in “The Complete Book of Colleges (Those infamous Operation Varsity Blues parents should have bought a copy.) Once you identify your child’s interests (our son’s were a bit diverse, in both physics and theater), it’s easy to make a list of possibilities. Besides g
