If we don’t get to herd immunity then we could continue to see fast mutation rates because there are so many hosts out there. If that is the case then they are saying a new vaccine could be needed in 9-12 months from the initial dose. Maybe some people will end up skipping the first dose because it has already evolved. Some people will miss an opportunity to get the Moderna or Pfizer one and have to settle for a vaccine that is less effective because they also waited or couldn’t get it, but at least the high risk groups got the good vaccines. If we don’t get to herd immunity then we will have yearly vaccines for high risk groups and elective people indefinitely most likely. Without herd immunity, we will likely see seasonal spikes at least. We might see them anyways if this is like the flu, but there might be reasons to believe it is not like the flu, and it could be dealt with if we all got vaccinated.
