As an AI language model, I don't have access to the most recent or up-to-date information on the Stefan Lanka measles virus trials in Germany. However, based on my research, it appears that Stefan Lanka is a German biologist who has been involved in controversial research on the measles virus and has claimed that the virus does not exist.
In 2015, a German court ruled against Lanka's claim and ordered him to pay a reward to anyone who could prove the existence of the virus. Subsequently, a doctor named David Bardens provided evidence of the virus's existence and was awarded the reward.
However, I am not able to provide information on the final outcome of any trials related to Lanka's research. It's always best to seek out information from reliable sources and fact-check before believing or spreading any information.
