Commentary I was a young vaccine research scientist when SARS-CoV-1 emerged in China and spread around the world in 2003, killing 811 people. Our team jumped on the newly available SARS-CoV genomic sequence, applying the then state-of-the-art bioinformatics tools to design a vaccine against the disease. In the end, the project did not move forward as the disease eventually disappeared. Seventeen years later, when SARS-CoV-2 emerged, I had already moved on to a new career. Like a retired baseball player watching the World Series, I could not help but call balls and strikes on what was going on. Of course, what we have witnessed so far is quite remarkable. Brilliant scientists, using today’s even more advanced technologies, developed vaccines against COVID-19 with lightning speed. It was truly a miracle that a vaccine could be developed, manufactured, and delivered to people in less than a year after the genome sequence of …
