Can You Make a Vaccine for This Virus if the Mutation Never Changes?

Could you make a vaccine for this if the virus never mutated? I think the answer is yes, and I believe the reason that The researchers said they'd never be able to make a vaccine is because the mutation. So many people were involved It would be hard to imagine they all had financial intention but there still leave some wiggle room about whether there was intent. They wanted it to work. They wanted to be heroes. Everybody wanted the pandemic to end so I think it was just wishful thinking That Blinded them to the obvious fact that they should have mentioned the moment this thing mutates the virus the vaccine won't work.
