Johnson & Johnson's COVID-19 Vaccine Is 66% Effective in Global Trial.
The single-shot vaccine was found to be 66% effective against moderate to severe illness in a global phase 3 trial.
Against severe disease, the vaccine was 85% effective globally in adults of all ages and racial groups.
In the United States, the vaccine was 72% effective against moderate and severe disease.
Despite other vaccines being around 95% effective, experts say the Johnson & Johnson vaccine will still be useful.
A vaccine that's inexpensive, that's a single dose, and that has no cold chain requirements — that's pretty good.
