This is the correct answer. Vaccine side effects aren't symptoms, they're side effects. You can travel at any time regardless of when you received the vaccine.
Now, depending on how bad your side effects are (I know a number of people who were pretty messed up for a few days after their second shot), you may not want to fly as it would likely be a pretty miserable experience.
