I asked my dad this who's a virologist, and he said this isn't known yet, but it's likely that there isn't really a correlation. The symptoms of the vaccine and the antibody production are caused by two different mechanisms. The first is the innate response which reacts to any antigen and triggers inflammation, fever, etc. The second is the adaptive immune response where your body develops memory B cells which produce neutralizing antibodies that bind to the spike protein and prevent it from entering a cell, and killer T cells which identify infected cells and kill them before the virus can replicate and spread. If you didn't get a fever from the vaccine, it just means that the innate response didn't cause noticeable symptoms, but it doesn't mean that the adaptive response wasn't strong.
