Travelling abroad is getting less complicated as a growing list of countries is reducing or eliminating quarantine and Covid-19 testing requirements for those who have been fully vaccinated, while keeping restrictions in place for those who haven’t. CNBC reports that Barbados announced this week that quarantine requirements for vaccinated travelers will be reduced while the US state of Hawaii is currently working on letting vaccinated visitors bypass testing and quarantine requirements and Phuket, Thailand, and Greece have indicated less restrictive vaccine-based protocols are in the works. Responding to questions of fairness or discrimination involved in these practices, Harry Nelson, the founder of Los Angeles-based health care law firm Nelson Hardiman citedlong-standing precedents for countries imposing proof of vaccinations for visitor entry, particularly with yeIlow fever, saying the ongoing threat of Covid-19 variants makes it “fully reasonable for countries to impose vaccination requirements.”
