Mehrmaz Campbell hadn't seen her son in well over a year.
"He's been wanting to come over for a long time since I think it was March 2020. It's just so nice to have him here," said Campbell,

"Now is the time to book Europe and now is the time to book a cruise cause they are the things that have availability for the future. Caribbean or Mexico, there's not much space available on resorts or flights," added Maureen Ward of Premier Travel.
The U.S. will accept travelers who have been fully vaccinated with any of the shots approved for emergency use by the World Health Organization, not just those in use in the U.S. That's a relief for many in Canada, where the AstraZeneca vaccine is widely used.
