Depends who you ask I think. CDC there seems to say you can get it as soon as you're recovered and met the criteria for discontinuing isolation. In the UK, the recommendation is 28 days from a positive test or onset of symptoms, whichever was first.
There's an article that seems to cover the various viewpoints reasonably well here:
https://www.health.com/condition/in...avirus/covid-booster-after-covid-breakthrough
I think my view would be that you can get it reasonably soon once you're recovered, there doesn't seem to be any particular reason not to, and it may be of benefit (plus it may be required depending on what you're doing, whether there's a fully vaccinated requirement, and whether having had a booster is part of that requirement).
Hope you recover quickly and well.
