Fully vaccinated Americans can resume travel, updated CDC guidance states

The CDC admitted that whilst they would prefer if people stayed at home and avoid travel, they had enough evidence as to the effectiveness of the vaccines, which showed people could travel "at low risk to themselves".

The CDC's new guidance comes as Americans gear up to travel around the country to celebrate Easter this weekend.

The new CDC guidance specifically greenlights vaccinated grandparents getting on airplanes to see grandchildren.

The CDC also recommends that people get tested three to five days after travel.

The Centers for Disease Control and Prevention (CDC) is struggling to give consistent and clear messaging on what vaccinated people should and should not do.

- Specifically, the new guidance today speaks to travel. They do not need to quarantine.

Just four weeks ago, the CDC held its ground with regards to their no-travel mantra by announcing that Americans should avoid all travel - even those who had been fully vaccinated against Covid-19.

Already, air travel in the United States has been picking back up. The last time the number of airport passengers screened was below 1 million was March 10.

The airline group praised the CDC's "updated travel guidance" that eases "travel restrictions for fully vaccinated individuals".

The CDC had repeatedly declined in recent weeks to change the guidance and repeated it was still discouraging all non-essential travel because of a concern about new variants. It also said vaccinated people could visit with unvaccinated people from a single household under similar conditions, as long as the unvaccinated individuals were at low risk for severe illness if infected.

The U.S. began its vaccine rollout in mid-December. Full immunity doesn't kick in until two weeks after getting the second shot of the Moderna or Pfizer-BioNTech vaccines or two weeks after getting the Johnson & Johnson shot, the agency said. A one-shot vaccine by Johnson & Johnson was given the green light by regulators at the end of February.
