The news of this new study just came out today. Give the guy a break.
No, as other commenters pointed out coronaviruses are different from the flu viruses in that they cannot mutate as easily as flu does. Hence it is possible that booster shots will not be required.

Nope, and for the same reason COVID deniers who claimed "it's just like the flu" in the beginning were wrong.
