"Is J&J's COVID-19 shot Good Enough? Experts say yes but Want More Data"

USA Today interviewed Dr. Timothy Brewer, UCLA Fielding School of Public Health professor of epidemiology, about the efficacy of the Johnson & Johnson vaccine, and whether recipients should get additional boosters

Thursday, July 22, 2021

When Johnson & Johnson's COVID-19 vaccine was authorized for use in late February, public health officials emphasized that it was just as good as the others. It was less effective, but because it requires only a single shot for full protection and is easier to distribute, it was a top choice for many people.

Since then, the J&J vaccine has been given far less often than the other two authorized vaccines, accounting for one-tenth as many shots as Moderna's vaccine, which is given less often than Pfizer-BioNTech's.

Recently, three pieces of information have come to light making people who got the J&J vaccine wonder whether their shot might be a distant third in other ways, too.
