I think each year’s flu vaccine is a slight modification on an existing vaccine. This may well (read: I have no idea, but it sounds plausible) make it faster to safety test the flu vaccine than a vaccine for a novel disease.
This is correct. We have lots of infrastructure and expertise for making new flu vaccines every year. It’s not a good model for how long we should expect safety testing to take for a vaccine for a new virus. We don’t have any licensed vaccines for any coronavirus, for example.
