Centers for Disease Control and Prevention lists safer activities you can choose after full vaccination.

​Centers for Disease Control and Prevention (CDCT) shared what to do when you have been fully vaccinated, and how you can safeguard yourself and others. Individuals fully vaccinated can gather indoors with other fully vaccinated people without wearing a mask or practicing social distancing.  The same rule applies for family and friends who do not reside in the same household, unless anyone they live with has an increased risk for severe illness from COVID-19.  You can host outdoor activities without wearing a mask, but there may be certain crowd activities that require restrictions.
For travel outside the United States you do not need to be tested before or after travel, nor will you need to self-quarantine after travel.  CDC does request those who fly research the policies for international destinations BEFORE traveling outside the United States.
At the date of this article, American Samoa continues to require testing before travel, as well as self-quarantine in Honolulu and Pago Pago for those returning.  You are still required to show a negative test result or documentation of recovery from COVID-19 in American Samoa, which follows the rules for CDC for international travel.  CDC continues to recommend testing 3-5 days after international travel, but there is no need to self-quarantine after arriving into the United States.
It’s important to note we are still learning about the pandemic, as well as efficacy of vaccination.  For those reasons you still should protect yourself and others by wearing a mask that fits snugly.  Be precautious when attending indoor public gatherings, and when visiting unvaccinated people.  Visiting indoor with an unvaccinated person who is at risk increases risk of severe illness or death from COVID-19.  If you want to learn more, please visit CDC, Covid-19 website.
