New CDC (Centers for Disease Control and Prevention) rules have become known for those who have already gone through the full vaccination process:
- Vaccinated persons can resume their travel: they do not need to undergo a coronavirus test before and after the flight, and they do not need to quarantine for two weeks after travel.
- Also, fully vaccinated people have the right to travel abroad without prior testing for COVID-19, except when requested by the host.
- In addition, fully vaccinated citizens must continue to take safety measures while on the move: wear a mask, keep their distance, and wash their hands.
- Fully vaccinated individuals do not need to self-quarantine after returning to the United States unless required by the state or local regulations.
A medical report published at the end of March showed that popular biphasic vaccines prevent 90% of infections, which is a very high rate.
Vaccines are believed to fully protect humans two weeks after the second dose of vaccines such as Moderna or Pfizer, or two weeks after a single dose from Johnson & Johnson.
