I think one must be careful to separate personal health beliefs from unproven/unknown science. In particular there is no specific evidence based guidance re: COVID vaccination and not being able to resume athletic activity though I could not find anything about whether strenuous activity is any different. It really is not the same as fighting an infection. Most people will not have an inflammatory reaction post vaccine though some certainly do. In fact, here is some evidence re: exercise actually boosts antibody response post flu/COVID vaccinations. However if one is having a side effect (eg fever, fatigue post vaccine) that suggests an inflammatory reaction then common sense would dictate that we listen to our bodies and not exercise which would be similar advice if we were acutely ill with an infection. I also would not get a vaccine too close to a race only because I'd be so pissed to have paid money and not be able to race if I were unlucky enough to have a reaction, not that I would be putting myself at risk for a reaction.
Sorry I should have said "if recovering from post vaccine adverse reaction". Better to take down time. While there may be no data, we have several centuries of common sense to say that if you are coming off a fever better back off. Maybe the data will catch up, maybe it won't. The data may never be there because there may not be enough people reporting back adverse affects and even then you have to define "adverse affect" which could be a very wide continuum.
Anyway, its a personal choice if we hammer hard after a fever whether illness generated or vaccine generated.
