i too have reservation on the speed of the covid19 vaccine development....the efficacy bar is set very low, just above 50% and it is good to go....there's the balance between speed and efficacy. But due to the severity of the pandemic, speed is pushed ahead with the assumption that even if 50% effective, it will reduce the future impact by at least that quantum post vaccine approval and public distribution.

Likely that covid19 strain will be part of the bi yearly flu vaccination in the days ahead. Strong and long lasting immune response towards coronavirus has generally been elusive.

If not, there won't be yearly flu vaccines, it will look more like a regular vaccination schedule for a new born child with a booster dose before they reach adulthood.
