It is not uncommon to have swellings after vaccinations. It has been reported with the covid vaccine. It should go back down on it's own in a week or two. If it remains after that, then speak with your GP about it.
If it gets bigger, red, or sore, in the meantime, then contact your GP sooner, as it might be an infection.
