COGEM invites you to join the 2023 international symposium ‘Viruses, Replicons and Vaccines: opportunities, risks and regulation’, an international symposium on advancements in viral research and applications of viruses for medical purposes, which will be held on Thursday, the 9th of March 2023 in Amsterdam. Over the last few years, a range of new and promising techniques have been developed concerning genetically modified (GM-)viruses. These GM-viruses can be employed for different medical applications, such as virotherapy to combat cancer cells, or as vaccines, like the Janssen and AstraZeneca vaccines against COVID. In view of these developments, COGEM has decided to organize an international symposium to provide more insight into the current developments and the future applications of viral vaccines, oncolytic viruses and replicons, – amongst which the self-amplifying mRNAs -. Simultaneously, the opportunities, potential risks and implications for biosafety and policy that are associated with these advancements, will be explored.
