Entry requirements: To enter Germany, U.S. residents must present evidence of vaccination, a recent negative coronavirus test or proof of immunity. If presenting a negative test, you may use either a PCR or rapid antigen test. PCR tests must be taken less than 72 hours before you land in Germany, while antigen tests need to be conducted less than 48 hours before arrival. We scheduled a PCR test for our daughters at a Walgreens drive-through two days before our departure. To prove you were infected with and recovered from the coronavirus, you must show a positive PCR test that was taken between 28 days and six months before your trip; you must also display no symptoms.
