Health & Safety

We are committed to a safe ISHL12. In order to ensure the usual interactive participation of all interested hematologists worldwide, ISHL12 will be a hybrid congress with the possibility of both in-person or online attendance. At present, there are no special requirements by German regulations with regard to COVID-19 due to low incidence and hospitalization rates. For on-site participation, we strongly encourage full vaccination with a WHO approved vaccine and regular self-testing. While masks and official testing for gatherings are currently not mandatory, we will provide a limited number of FFP2 masks on site and COVID-19 testing is available in close vicinity of the Gürzenich. The official COVID-19 measures are updated regularly and, if required, will be fully enforced at ISHL12, to enable safe on-site participation for everyone. Further information is provided by the Federal institute for Vaccines and Biomedicine including a document with versions of EU-authorised vaccines authorised abroad (original or licensed productions) which are equivalent to the named EU-authorised vaccines as proof of vaccination protection. Further information from the federal state of North Rhine-Westphalia can be found in various languages.

Depending on the situation end of October 2022 and requirements by German regulations, additional COVID-19 testing requirements might apply. We will follow local requirements by German regulations in regards to masking, and will update our homepage if necassary.

If you cannot or choose not to comply with ISHL’s health and safety protocols, or if you are unable to come to Cologne, please join us online. If you will not be fully vaccinated by the time of the congress and are registered for the in-person participation, you may change your registration to online. Please revisit the registration website.
