How COVID-19 vaccines were made so quickly without cutting corners Driven by a global urgency and underpinned by decades of prior work on vaccine technology, vaccine developers found a way to chop not just days or months, but years off the timeline.

But many questions remain about who is most at risk, how the risk-benefit calculus changes when cases fall, and what the side effects mean for the future of these vaccines, which use adenoviruses to ferry the gene for SARS-CoV-2’s spike protein into human cells.
