As coronavirus vaccinations ramp up in the United States, many grounded travelers are likely looking forward to planning their first fully vaccinated getaway—perhaps booking a long-awaited flight to visit family they haven’t seen since last year.

And while there is good reason to celebrate inoculation, health officials have warned that a vaccination is not a free pass to travel as we used to. This is largely dictated by the undetermined degree to which vaccinated people can transmit coronavirus; until everyone is inoculated against COVID-19 or it is proven that vaccination prevents transmission, vaccinated people will need to continue masking and social distancing to protect those who are unvaccinated.

But while post-vaccine travel isn't without some risks, some activities—including being able to more confidently fly, returning to places lifting restrictions for vaccinated individuals, and gathering with other vaccinated people—do become safer, experts say.
