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. As the safety of our attendees is our top priority, proof of being fully vaccinated against COVID-19 will be required for all in-person attendees. “Fully vaccinated” means two weeks have passed since receiving the second dose double-dose of a COVID-19 vaccine. 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.

Further detailed specifications will be provided in due time. Depending on the situation in 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 as we approach the congress.

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.
