It means that anyone who wants to enter Germany from abroad still has to stick to the coronavirus entry rules.
Before coming to Germany, people over the age of 12 are asked to upload or show their Covid documents (proof of vaccination, recovery or a negative test) while checking in or before boarding. This is known as the 3G rule in Germany.
Travellers who are transferring at an airport in Germany also have to present proof of their Covid status before arriving in the country. This applies both to non-Schengen transit from or to third countries outside the EU and to transit from or to Schengen states.
