You can't use the flu to draw conclusions about the efficacy of the coronavirus vaccines or the impact of mutations on their efficacy.The mutation characteristics are different between the flu and the coronavirus. Some viruses, such as measles, are pretty stable where it matters so the vaccine continues to work. The developers are expecting the vaccines to be viable for a longer period of time than the flu vaccines. How long? We will see. There is a lot of information available about the Pfizer/BioNTech and the Moderna vaccines.

Covid 19 perhaps as in Florida is spreading more rapidly than expected. The story, if correct, said it is a new strain.
