The department on Monday raised its travel advisory level for the UK to “Level 4: Do not travel” due to Covid-19. The decision, which aligns with a separate US Centers for Disease Control and Prevention update, comes the same day that Prime Minister Boris Johnson lifted most of England’s remaining pandemic-related restrictions.

Noting the CDC’s decision earlier Monday to raise its UK Risk Assessment Level for Covid-19 to “Level 4: Covid-19 Very High,” the department said in its updated travel advisory that there “are restrictions in place affecting US citizen entry into the United Kingdom.”

“Your risk of contracting Covid-19 and developing severe symptoms may be lower if you are fully vaccinated with an FDA authorized vaccine,” the advisory continues. “Before planning any international travel, please review the CDC’s specific recommendations for fully vaccinated and unvaccinated travelers.”
