We don't have a true flu vaccine, which I guess is why we have a "flu shot."

What is the likelihood we won't have a true "SARS-CoV-2" vaccine that stops the virus like a Measles or Polio vaccine, and instead we'll have the equivalent of the flu shot for it, something that might lessen the chances someone gets Covid-19, but if they do, makes the impact less severe than it would be otherwise in most but not all cases?

What do you mean, we don't have a true flu vaccine?  There are aspects of influenza that make it different from measles or polio, but that makes it no less of a vaccination.

When I think of "vaccine" I think of something that works 100% effective or close enough that it creates herd immunity for diseases like measles and polio.  I've never heard of a flu vaccine. Everyone always calls it a flu shot.  Maybe it is in fact a vaccine, but that's not what it's commonly called, ostensibly because it isn't full proof. Plenty of people get the flu who had flu shots/vaccine.

Therefore, my question is based on concern the SARS-CoV-2 vaccine will have similar efficacy to a flu shot, which is to say not all that much. I can't justify getting a flu shot.  I've never had one and only had any bad flu one time in my life.
