Vaccinated people can resume travel at 'low risk' -CDC

The new CDC guidance specifically greenlights vaccinated grandparents getting on airplanes to see grandchildren.

A group representing major U.S. airlines including American Airlines, Delta Air lines, United Airlines, Southwest Airlines and other trade groups had urged the CDC on March 22 to immediately update its guidance to say "vaccinated individuals can travel safely." Air travel still remains down 43% from pre-COVID levels and business and international travel remain even harder hit.

The new guidance also says fully vaccinated people do not need to get a COVID-19 test before or after domestic travel and do not need to self-quarantine after travel.
