Your deaths are high for flu. I'd say ideally, if we know Covid is under control globally, and we have widespread distribution of various vaccines that can be used in different parts of World, we should see deaths in the same realm as the seasonal flu. What we have found out though is Covid is not seasonal and can be a year round virus, so we are likely to see a greater emphasis placed on it than the flu when it comes to vaccinations and time period between dosing. Maybe it's once every 6-9mo. Who knows until more efficacy data comes in from the ongoing long term trials.
