1. Participation Restrictions

We want to ensure a safe event for all of us and further comply possible restrictions of our government. Therefore, all participants need to have the highest protection against COVID-19 under German law (Reference: Corona Act of the federal state of Lower Saxony, accessed on 30.01.2022, only in German), which includes

  • 3 vaccinations or
  • 2 vaccinations and a recovery (in any order).

Notice, that only the following vaccines, which are licensed in Germany at the moment (Reference: Paul-Ehrlich-Institut, accessed on 30.01.2022), are accepted:

  • Comirnaty (BioNTech/Pfizer)
  • Spikevax (Moderna)
  • Janssen (Johnson&Johnson)
  • Vaxzevria (AstraZeneca)
  • Nuvaxovid (Novavax)

We are going to check your vaccination status latest at your arrival in Hannover and have to suspend you from participation in case of false data.

2. Entry restrictions into Germany

The restrictions vary depending on whether you are entering Germany from a country inside or outside the European Union (EU)/Schengen Area.

Traveling inside EU/Schengen Area: One needs a proof of vaccination and/or recovery (2 vaccinations, or 1 vaccination plus 1 recovery) or a negative COVID-19 test result (not older than 48h).

Entering from outside the EU/Schengen Area: A full vaccination is required which comprises by definition 2 vaccinations, or 1 vaccination plus 1 recovery. Please inform yourself in which form you have to provide the proof.

Since our event-specific restrictions are even higher than the entry restrictions, you should not encounter any problems at the entry control in this matter.

The current entry regulations are given by our Federal Foreign Office and the Federal Ministry of the Interior and Community. Please check also information given by the German Embassy or Consulates General in your country.

3. Local regulations in Hannover/Lower Saxony and Hamburg

The city of Hannover lays in the federal state of Lower Saxony while the city of Hamburg is a federal city state. The rules for daily behaviour can differ in these two cities where you are going to be. General information can be found at the German National Tourist Board, when you enter the federal state you want to know more about. The city of Hamburg provides also information in English language by itself. Unfortunately, the city of Hannover and the federal state of Lower Saxony provide only information in German language.

In recent weeks most of the rules for daily behaviour have been dropped and were transformed into recommendations, such as wearing a mouth-nose protection in closed rooms and crowded places, or making sure to keep enough distance from fellow humans.

However, there are still some rules that affect our event:

  1. It is still mandatory to wear an FFP2-mask (or a mask with a similar standard) in public transport vehicles (trains, trams, busses, ferries etc.) and at the stations.
  2. For restaurants, stores, companies etc. it is possible to provide mask obligations for within the scope of the house right. This possibility is also used by the Leibniz University Hannover, which is why there is an FFP2-mask obligation in all university buildings, where a lot of the program items will happen.

4. Rules during the event

In accordance with the rules in force at the time of the event (see point 3), we set up a comprehensive FFP2-mask obligation. A detailed list with the locations where you have to wear a mask will be published in time before the event. Be prepared to wear a mask frequently, so make sure to bring enough FFP2-masks with you since they have a limited durability.
