Blood samples from recovered patients suggest a powerful, long-lasting immune response, researchers reported.

Some excellent research suggests immunity will last for a *very* extended period of time and yearly vaccinations will be unlikely.
tl;dr - patients who recovered 8 months ago have very little diminished immunity. Runs in line with folks who recovered from 2003 SARS outbreak, another coronavirus, who still have T-cells 17 years later.
Given Moderna's vaccine only requires normal freezer storage, that'll ease distribution capabilities. I strongly believe that if the general public sees these vaccines are highly effective, aren't necessary yearly, and will greatly speed the return to mask-less and social distance-less life that the vast majority will get vaccinated.
Add on top of that, you can bet that once an approved vaccine is available to anyone who wants one it'll be a requirement to do things like send your child to school, enroll in college, work in an office, perhaps even as much as go to a concert or sporting event.
The science here is strong. Public officials and scientists need to do a much better job of clearly informing the public and presenting the research than they did in the spring on things like the efficacy of social distancing and mask-wearing.
Bat down these nonsense claims of "we've never developed a vaccine this fast!!!!" with facts. There's no other time in human history that we've *tried* to develop a vaccine this fast with this level of urgency. That'd be like if they said in the middle of the 20th century "Well, no one's ever been to the moon. So I guess it's not possible and I think anyone who says we can is a liar."
