This is an excellent question. I watch everything that Dr. Greg Poland says and follows his advice but I also love to have things in writing so I take notes!

The first thing that you need to do is to wait for about 2 weeks for the vaccine to really kick in and be effective. During this time you need to keep protecting yourself as if you hadn't been vaccinated. Maintain distance, wash your hands wear masks, and keep any socializing to a minimum and outdoors if possible. It is still possible to give COVID-19 to others and to get it yourself.
