WATCH: How the Johnson & Johnson COVID-19 vaccine works

Johnson & Johnson's COVID-19 vaccine was the third to be authorized in the United States, but it was the first to deliver full protection with one shot. Also different from the mRNA-based vaccines developed by Pfizer and Moderna, this one uses a "viral vector" -- in this case, an adenovirus -- to inoculate recipients against the coronavirus. On Thursday, Johnson & Johnson announced that new data from small studies suggest that its vaccine protects recipients against the more transmissible delta variant of the virus, and that overall protection lasts for at least eight months. Here’s a look at how it works. Video by Megan McGrew and Isabella Isaacs Thomas/PBS NewsHour Editor’s note: Johnson & Johnson is a funder for the PBS NewsHour.
