All the vaccines are good. It's not worth getting into a question of which is the best. They're all good enough to use.
The problem we have is getting more of them, and getting them quickly, particularly now that it's become geopolitical.
In 1976, there was a swine flu epidemic, and the United States shut down exports of vaccines to Canada. I'm hoping that with the next question I can get to the issue of manufacturing, and how we can stay safe from that.
